This may sound like an old story to those who have been around since the adoption of WMS 1.3.0 in 2004, but believe it or not we still hit those 1.3.0 issues today 8 years later. The last time was a few weeks ago and that got me started on that same old rant once again. I figured that I'd archive a copy of it here once and for all, and next time I can just point people to this blog.<br />
<br />
<h3>
The long story</h3>
<h3>
</h3>
"Don't 'upgrade' to WMS 1.3.0 unless you really have to because it's a mess, stick to WMS 1.1.1 if you can"... well, I
may not have used those exact words, but I mean it, WMS 1.3.0 is a pain
to support properly, both on the client and on the server side, and
should be avoided unless you have very good reasons to switch to it,
like requirement for ISO compliance for instance. If you can stick to
WMS 1.1.1 then you will be much happier.
<br />
<br />
I was involved with the OGC revision working group (RWG) that worked on
the adoption of WMS 1.3.0 and I had the "chance" (or not?) to witness
what happened. The "problem" is that OGC was trying to get WMS 1.3.0 approved as an
ISO spec, and the ISO review process forced them to break compatibility with WMS 1.1.1 and
older on a few aspects in order to meet the very strict ISO requirements.
<br />
<br />
One of those aspects was a requirement to honour the axis order defined
by EPSG in its database of coordinate systems. In WMS 1.1.1 and older,
early day OGC WMS authors and implementers had made a "mistake" and always assumed an x-followed-by-y axis
order for coordinates, so the BBOX for EPSG:4326 (WGS84 geographic coordinates in
degrees) was treated as:
<br />
<br />
BBOX=lon_min, lat_min, lon_max, lat_max
<br />
<br />
But the EPSG database that WMS refers to defines the axis order for its 4326 SRS to be latitude followed
by longitude (or y-x for the mathematicians around the table), so in WMS
1.3.0, you have to use:
<br />
<br />
BBOX=lat_min, lon_min, lat_max, lon_max
<br />
<br />
However, for <b class="moz-txt-star">most</b> projected coordinate systems, EPSG still defines the
axis order as x followed by y, so nothing changes between 1.1.1 and
1.3.0 in those cases. For instance, with EPSG:3857 (Google Mercator projection in
meters), the BBOX coordinate order remains the same for both WMS 1.1.1 and 1.3.0:
<br />
<br />
BBOX=xmin, ymin, xmax, ymax
<br />
<br />
This strict compliance requirement imposed by the ISO review process on the OGC RWG means that WMS
1.3.0 server and client code needs to be aware of the axis order for
each SRS that it supports and to use the correct coordinate order in its
BBOX (and also the BoundingBox elements of the GetCapabilities output IIRC)... that's the
mess I was alluding to.
(There are a few thousand codes in the EPSG database that software needs to be made aware of.)<br />
<br />
The issues that we encounter the most often with WMS 1.3.0 implementation range from incomplete axis order support for some EPSG codes
to some implementations incorrectly assuming that WMS 1.3.0 just swaps the axis
order to y-x for every SRS. And yes, there are still some
implementations in 2012 that don't get this right.<br />
<br />
Note that to help work around this issue for those writing simple clients/servers who want to
avoid using EPSG codes and be free to continue with x-y axis order
everywhere, the WMS 1.3.0 RWG invented a new "CRS:*"
namespace for projection codes in which it defined a few well-known
coordinate systems. They are listed in Annex B of the WMS 1.3.0 spec. The most
common one is CRS:84 which is essentially EPSG:4326 with lon-lat (x-y)
axis ordering. Unfortunately this is just a patch and doesn't address the core issue which is a brutal incompatibility between WMS 1.1.1 and 1.3.0.<br />
<br />
<h3>
Examples</h3>
<h3>
</h3>
Since <a href="http://mapserver.org/">MapServer</a> complies with all those requirements, here are some example
showing the change in behaviors between WMS 1.1.1 and 1.3.0 with MapServer WMS, taking the following BBOX:<br />
<br />
bbox=-90,0,0,90
<br />
<br />
Using WMS 1.3.0 with EPSG:4326 (with lat-lon, a.k.a y-x axis order):<br />
<br />
bbox=-90,0,0,90&crs=EPSG:4326&version=1.3.0
<br />
<br />
this
bbox is interpreted as<br />
<br />
lat_min = 90 South
<br />
lon_min = 0
<br />
lat_max = 0
<br />
lon_max = 90 East<br />
<br />
and you get the following map image:
<br />
<br />
<div style="text-align: left;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgyyXH5c-b03w-kuqvRXzNg7L2yjbK2ROBvlm20vZOPGPfdEgYLZM4yt2B_nllDNVU6sBqdiku0V4KGWOw7o_jTItVoeuG3tyk7IysQy7log_anf9Fe8ee12b-9HYrnFIaStzdu_CLAiZA/s1600/wms-130-4326.png" imageanchor="1" style="clear: left; margin-bottom: 1em;"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgyyXH5c-b03w-kuqvRXzNg7L2yjbK2ROBvlm20vZOPGPfdEgYLZM4yt2B_nllDNVU6sBqdiku0V4KGWOw7o_jTItVoeuG3tyk7IysQy7log_anf9Fe8ee12b-9HYrnFIaStzdu_CLAiZA/s1600/wms-130-4326.png" /></a></div>
<br />
However, if you want to keep it simple and stick to x-y axis ordering,
and want the BBOX treated as
<br />
<br />
lon_min = 90 West
<br />
lat_min = 0 <br />
lon_max = 0
<br />
lat_max = 90 North
<br />
<br />
then you can either use WMS 1.3.0 with CRS:84:<br />
<br />
bbox=-90,0,0,90&crs=CRS:84&version=1.3.0
<br />
<br />
Or stick to WMS 1.1.1 with EPSG:4326:<br />
<br />
bbox=-90,0,0,90&srs=EPSG:4326&version=1.1.1
<br />
<br />
and in both cases you'll get this:<br />
<br />
<br />
<div style="text-align: left;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjCUEP7r8stNMv0ytfz9Gj_jipRgbglLt8t7ihXJ6tow_tz28M-wueFOlX6OCB6Gwgq76s_CtUobZ3lxD0fzdt-UWXsT7TF8ZI_-ioDffT6s8OSCS1hVb2u9quV4IefvImXdo7RHCPx014/s1600/wms-130-crs84.png" imageanchor="1" style="clear: left; margin-bottom: 1em;"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjCUEP7r8stNMv0ytfz9Gj_jipRgbglLt8t7ihXJ6tow_tz28M-wueFOlX6OCB6Gwgq76s_CtUobZ3lxD0fzdt-UWXsT7TF8ZI_-ioDffT6s8OSCS1hVb2u9quV4IefvImXdo7RHCPx014/s1600/wms-130-crs84.png" /></a></div>
<br />
<br />
Hopefully now you'll understand next time you hear me mumble "... stick to WMS 1.1.1...".<br />
<br />
P.S. Also note in the examples above that the WMS 1.1.1 "srs=..." parameter was renamed to "crs=..." in WMS 1.3.0, but that's a story for another day.

<br />
<a href="http://www.mapgears.com/">Mapgears</a> and <a href="http://www.mgeospatial.com/">Mgeospatial</a> just announced the merge of their respective geospatial consulting operations to launch a new division: <b>Mapgears Solutions</b>. Thus, it is with great pleasure that we welcome two new members in the Mapgears family: <a href="https://twitter.com/SimonMercier">Simon Mercier</a> and <a href="http://www.linkedin.com/pub/charles-%C3%A9ric-bourget/45/b31/789">Charles-Éric Bourget</a>.<br />
<br />
Technically, the new entity will be based in Quebec City and will operate under the direction of Simon Mercier, vice president of the new Mapgears Solutions division. Its mission will be to complement the technology offer of the current team based in Chicoutimi with highly specialized consulting services to assist customers in the setup and deployment of <a href="http://mapserver.org/">MapServer</a> and related open source technologies.<br />
<br />
Simon founded Mgeospatial a little over a year ago based on this same vision that will remain at the core of Mapgears Solutions. With respect to the current Mapgears team that you all know, we will now refer to it as Mapgears Technologies, and as the name says, it will continue to focus on the development and support of MapServer and related technologies, which is what we do best and has led us to where we are today.<br />
<br />
I am very glad that Simon accepted the opportunity to join Mapgears. The synergy between the two teams will allow us to better serve our clients and to accelerate the growth of the two entities who were having a hard time responding to the growing demand for our technologies and services. I already expect a few more names to join the teams in the coming months, stay tuned.<br />
<br />
BTW, Simon, Julien and I will be at <a href="http://foss4g-na.org/">FOSS4G-NA</a> in Washington next week and we'll be happy to discuss this further with you.<br />
<br />
P.S. With this announcement comes the need for a new website to better reflect today's Mapgears product and services offering. A preview of the new style is already available at <a href="http://www.mapgears.com/">www.mapgears.com</a> and the new site currently under construction should hopefully be available in the coming weeks.Daniel Morissettehttp://www.blogger.com/profile/00965593668999032765noreply@blogger.com1tag:blogger.com,1999:blog-808053412198379231.post-77782359191799106342012-03-27T10:14:00.000-04:002012-03-27T10:14:54.005-04:00FOSS4G North America only 2 weeks away - April 10-11<a href="http://foss4g-na.org/">FOSS4G North America 2012</a> is only two weeks away - April 10-12 in Washington, DC. <a href="http://www.mapgears.com/">Mapgears</a> is a proud sponsor of the event and I'll be there of course! <br />

As for any FOSS4G event, the most important part for me is the networking with other developers and users of <a href="http://www.osgeo.org/">OSGeo</a> software, so I look forward to seeing you there!Daniel Morissettehttp://www.blogger.com/profile/00965593668999032765noreply@blogger.com0tag:blogger.com,1999:blog-808053412198379231.post-36159635835624946972012-02-08T19:15:00.001-05:002012-02-08T19:16:40.147-05:00MapServer and TinyOWS Releases at the Islandwood OSGeo Sprint<div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhHuwGOShN5-MXvf5AcTddEeis4D1EQTMYyeJXC0-vw1fT2eo21Uni_fB8dOsvA_yoTv1XALSObSdxwEkiikxGNizBcwmyTsBqu9dy0RauFmfX-JGZTwu5bL5qj6xfkxnFkpGLDtca7iI4/s1600/DSC01793.jpg" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img border="0" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhHuwGOShN5-MXvf5AcTddEeis4D1EQTMYyeJXC0-vw1fT2eo21Uni_fB8dOsvA_yoTv1XALSObSdxwEkiikxGNizBcwmyTsBqu9dy0RauFmfX-JGZTwu5bL5qj6xfkxnFkpGLDtca7iI4/s320/DSC01793.jpg" width="320" /></a></div><br />
This week, 21 developers are getting together for a code sprint in the wonderful venue of <a href="http://www.islandwood.org/">Islandwood</a> to work on the advancement of their respective <a href="http://osgeo.org/">OSGeo</a> projects. Thanks to <a href="http://twitter.com/mpgerlek">Michael Gerlek</a> for organizing and to our <a href="http://wiki.osgeo.org/wiki/IslandWood_Code_Sprint_2012">sponsors</a> for their support.<br />
<br />
I am happy to report that <a href="http://tinyows.org/">TinyOWS</a> version 1.0 has just been released. Congratulations to Olivier Courtin for leading the project to this important milestone!<br />
<br />
Last summer it was decided that TinyOWS (<a href="http://mapserver.org/development/rfc/ms-rfc-70.html">RFC-70</a>) and MapCache (<a href="http://mapserver.org/development/rfc/ms-rfc-71.html">RFC-71</a>) would join the <a href="http://mapserver.org/">MapServer project</a>. This means that with the upcoming MapServer 6.2 release, we will also release the MapServer Suite which includes "mapserv" (the CGI/FastCGI), MapScript, MapCache and TinyOWS. The long term plan is to provide a more seamless integration of the tools under this MapServer Suite umbrella, while still allowing the use of each component independently or with other non-MapServer packages for those who wish to do so.<br />
<br />
Another outcome of the sprint is that the TinyOWS documentation has been integrated in the development tree <a href="http://mapserver.org/trunk/tinyows/">here</a>. Thanks to <a href="http://twitter.com/dmiddlecamp">David</a> and <a href="http://twitter.com/halm">Hal</a>, for their work on this and their other contributions. <br />
<br />
On the MapServer front, we just announced the<a href="http://lists.osgeo.org/pipermail/mapserver-users/2012-February/071476.html"> release of version 6.0.2 and 5.6.8</a>. There are no new features in those releases, only fixes, and they do include a fix for a security vulnerability that was found in the handling of WFS Filters inside SLDs, so you are encouraged to upgrade your installation. More details in the announcement <a href="http://lists.osgeo.org/pipermail/mapserver-users/2012-February/071476.html">here</a>.<br />
<br />
Finally, one of our next goals is to work out a plan for a MapServer 6.2 feature freeze and release this spring.Daniel Morissettehttp://www.blogger.com/profile/00965593668999032765noreply@blogger.com0tag:blogger.com,1999:blog-808053412198379231.post-63476168199096769552012-01-26T12:13:00.001-05:002012-01-26T13:22:52.400-05:00Intellectual Property vs CopyrightIn the past I have often used the terms <a href="http://en.wikipedia.org/wiki/Intellectual_property">Intellectual Property</a> and <a href="http://en.wikipedia.org/wiki/Copyright">Copyright</a> to mean essentially the same thing, without realizing that this was incorrect. Maybe that was because English is not my native language, but probably not since I have actually heard several others making the same mistake as well.<br />
<br />
This morning in a discussion on this topic on the <a href="http://lists.osgeo.org/mailman/listinfo/incubator">OSGeo Incubator mailing list</a>, <a href="http://fwarmerdam.blogspot.com/">Frank Warmerdam</a> explained the difference between the two terms and now I better understand why the terms Intellectual Property and Copyright should not be confused, especially in the context of Free and Open Source Software (FOSS).<br />
<br />
I thought I'd share a copy of Frank's great explanation here in case it helps others better understand the distinction:<br />
<blockquote class="tr_bq" style="font-family: Times,"Times New Roman",serif;">Daniel, <br />
<br />
I believe the rationale behind avoiding the term Intellectual Property <br />
has two parts. <br />
<br />
First, it attempts to conflate a variety of very different legal mechanisms. <br />
Primarily copyright, patents and trademarks. Giving them all one name makes <br />
it harder to separate out things we might agree with (copyright) from things <br />
we might not (ie. Patents). <br />
<br />
Second, it expresses these legal mechanisms in a manner that implies that <br />
they are some sort of fundamental or manifest right rather than limited <br />
government granted monopolies intended to serve specific needs of society</blockquote><blockquote class="tr_bq" style="font-family: Times,"Times New Roman",serif;">[...]</blockquote>You can read the full email and the rest of the thread <a href="http://lists.osgeo.org/pipermail/incubator/2012-January/001741.html">here</a>.Daniel Morissettehttp://www.blogger.com/profile/00965593668999032765noreply@blogger.com0tag:blogger.com,1999:blog-808053412198379231.post-40341867194462646582011-11-24T11:24:00.002-05:002011-11-24T11:35:49.202-05:00Time to Register for the February 2012 OSGeo Code SprintThe <a href="http://wiki.osgeo.org/wiki/IslandWood_Code_Sprint_2012">2012 OSGeo Code Sprint</a> is approaching fast: February 5-9, 2012 at <a href="http://www.islandwood.org/">IslandWood</a> (near Seattle).

<br />
I am very excited to welcome Jessica Lapointe and Vincent Foley who just joined the <a href="http://www.mapgears.com/">Mapgears</a> team in the last few weeks. This influx of new blood aims at increasing our ability to respond to the growing demand for <a href="http://www.mapserver.org/">MapServer</a> and related open source technologies of course, but for Mapgears, this is also (and mostly) an investment to insure that we can continue to innovate and revolutionize the field of mobile and web mapping for years to come.<br />
<br />
Jessica is an entrepreneur. Despite her young age, she already shines at the international level (just like Mapgears!) with her font production business: <a href="http://cuttyfruty.com/">CuttyFruty.com</a>. She developed her interest for font sets when she was 13, and today, her fonts are being used by big names such as Lise Wathier, Barbie, Microsoft and Rihanna. (Read more <a href="http://www.forcesavenir.qc.ca/en/collegial_finalistes/finaliste_view/24">here</a>.)<br />
<br />
Even if her first start-up was very artsy, Jessica also has a passion for software and web development, and she actually won some prizes in that field. She is in the process of completing a bachelor's degree in computer science, and it is as a software developer that she joins our team. I am already looking forward to what her exceptional combination of artistic and programming skills will bring to the web mapping world.<br />
<br />
With respect to Vincent, he combines experience in web development with a solid knowledge of Linux and the set of software development tools used by MapServer and several other OSGeo technologies. As part of our team, he will be working at the lower level of the architecture on the server side, the less visible, but no less critical part of the web mapping stack.<br />
<br />
The users of <a href="https://wiki.ubuntu.com/UbuntuGIS">Ubuntu GIS</a> will have a chance to appreciate his contributions fairly soon as he is currently working with Alan to port the OSGeo UbuntuGIS packages to Ubuntu 11.10 (oneiric). Stay tuned!<br />
<br />

The answer is "it depends": it depends on the license of the open source components that you use and how the components are being used in your application.<br />
<br />
This question came up again today on the <a href="http://gdal.org/#index_maillist">gdal-dev</a> discussion list, and Even Rouault posted <a href="http://lists.osgeo.org/pipermail/gdal-dev/2011-July/029481.html">an answer</a> that summarizes very well the obligations related to the most common licenses in our field: <a href="http://www.gnu.org/licenses/licenses.html#GPL">GPL</a>, <a href="http://www.gnu.org/licenses/licenses.html#LGPL">LGPL</a>, <a href="http://opensource.org/licenses/BSD-2-Clause">BSD</a> and <a href="http://opensource.org/licenses/mit-license.html">MIT/X11</a>.<br />
<br />
I reproduce Even's answer here for reference as a starting point for next time someone asks:<br />
<br />
<pre wrap="">... here's my understanding of the obligations of the licences. Take it with a
grain of salt : "I'm not a lawyer".
* If your application links to a GPL library, the whole application, including
your own code, is bound by the GPL. You must include the appropriate copyright
notice for the library and provide the user access to the source code of the GPL
library (including the modifications you may have done) and to the code of your
application too under the terms of the GPL.
* If your application links to a LGPL library, you must include the appropriate
copyright notice for the library and provide the user access to the source code
of the LGPL library (including the modifications you may have done in it). Your
application itself may be released under the terms you like.
* If your application links to a BSD library, well, that's depend of the BSD
licence. There are 2-clause, 3-clause and 4-clause variants of the BSD
licence... If it includes the following clause "Redistributions in binary form
must reproduce the above copyright notice, this list of conditions and the
following disclaimer in the documentation and/or other materials provided with
the distribution", well just comply with it. Otherwise, if you don't distribute
any source code (and you don't have to), you have nothing to do. In any case,
the licence only covers the library code, not your application.
* The MIT licence is a bit similar, except that, the general understanding is
that it places no obligations if you distribute the library as a binary object.
But I've always found that the term "the Software" in the licence isn't very
explicit if it only covers only the source code or binaries generated from it.
So it might be nice to include the copyright notice somewhere if you distribute
it as a binary. If you distribute it as source code, it's clear that you must
include the copyright notice.

In addition to the actual coding and project meetings, those sprints provide a unique way to build and maintain synergies between the projects and their developers.<br />
<br />
On the MapServer front, the focus was on the <a href="http://mapserver.org/trunk/development/release/release-plan-6.0.html">6.0 release</a>. MapServer 6.0.0-beta2 should be released later this afternoon with the outcome of the sprint work.<br />
<br />
Ruby bindings for MapServer and GDAL were brought back into maintenance, and some enhancements were made to the Oracle (OCI) driver in OGR.<br />
<br />
The LibLAS group has been planning and setting up the bases of the new <a href="http://libpc.org/">libPC</a> (PC for <a href="http://en.wikipedia.org/wiki/Point_cloud">Point Cloud</a>), which will provide a generic interface to point cloud data formats. Think of libPC as the GDAL of point clouds.<br />
<br />
The PostGIS team moved closer to the PostGIS 2.0 release with core changes to indexes, better support for <a href="http://www.quantdec.com/SYSEN597/GTKAV/section9/map_algebra.htm">raster map algebra</a>, and several tickets closed on shp2pgsql.<br />
<br />
The ZOO Project team worked on a new WPS service for athmospheric dispersion to simulate the dispersion of the cloud that spreads from the Japanese nuclear power plants. The team also made some good progress (testing and docs) towards the upcoming ZOO 1.2 release.<br />
<br />
A MapServer mapfile parser has been added to TinyOWS to directly read the layer configuration information from a MapServer mapfile. This addition will significantly facilitate the use of TinyOWS as a WFS-T to complement MapServer.<span style="color: black;"><span style="font-size: small;"> </span></span><br />
<br />
<span style="color: black;"><span style="font-size: small;">The GeoPrisma team got together to add support for two new service types (OGC WFS and WPS), as well as fixes to the print widget and some general security issues. They also started to build demos integrating the latest version of most projects present at the sprint including: MapServer, TinyOWS (with mapfile support), GeoPrisma, Zoo-Project and WKTRaster. Stay tuned to see this demo in action (link not available yet).</span></span><br />
<br />
<span style="color: black;"><span style="font-size: small;">And of course there was the social side of the program, with a hockey night on Thursday, and hours of talk and lots of new ideas exchanged informally during the social events each night. </span></span></div><div class="separator" style="clear: both; font-family: inherit; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi5qOgOGpzkEIcQIbOB0i-_ChK-cEpD1c4RYwOIJTPHhTnuI8_5aAa9xzJLYkpn4PmmtfUoKa3NczF_y0XDX0FS6xdOTSFQyvFr6tdLDHyh6dpSbWNNoZbPU1Sh7pfpT6Uf_d49Vp8VOzQ/s1600/2011-03-17+20.26.54.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi5qOgOGpzkEIcQIbOB0i-_ChK-cEpD1c4RYwOIJTPHhTnuI8_5aAa9xzJLYkpn4PmmtfUoKa3NczF_y0XDX0FS6xdOTSFQyvFr6tdLDHyh6dpSbWNNoZbPU1Sh7pfpT6Uf_d49Vp8VOzQ/s320/2011-03-17+20.26.54.jpg" width="320" /></a></div><div style="font-family: inherit;"><br />

<br />
<span style="color: black;"><span style="font-size: small;">Finally, there are already talks about the 2012 Code Sprint which is likely going to take place in Seattle (see <a href="http://lists.osgeo.org/pipermail/tosprint/2011-March/000245.html">here</a>).</span></span><br />

Thanks!</i></b> </blockquote><br />
The <a href="http://wiki.osgeo.org/wiki/Montreal_Code_Sprint_2011">Montreal Code Sprint</a> of March 15-18, 2011 has reached a record of <a href="http://wiki.osgeo.org/wiki/Montreal_Code_Sprint_2011#Participation">29 registered participants</a> from 9 open source projects as of yesterday. This is awesome news for <a href="http://www.osgeo.org/">OSGeo</a> and its projects that will get a significant boost of code and contributions during that week!<br />
<br />
The downside of this is that our initial budget was for ~20 participants, and with close to 50% more sprinters we need to adjust the budget accordingly and are turning to you to help us find more sponsors to balance the <a href="http://wiki.osgeo.org/wiki/Montreal_Code_Sprint_2011#Budget">new budget</a>.<br />
<br />
<b>CALL FOR NEW SPONSORS - An investment in the technology that you use!</b><br />
<br />
We are looking for another round of sponsors ($750 each) to support food and fun for the sprinters as they work hard and play hard for four productive days. Each $750 sponsorship will be put towards lunch, snacks and dinner costs for the sprinters, and any surplus at the end of the event will be turned over to OSGeo or used for a future code sprint.<br />
<br />
If your organization is using one of the software projects listed below, then please consider this <a href="http://wiki.osgeo.org/wiki/Montreal_Code_Sprint_2011#Sponsors">call for sponsorship</a> as <b>an investment in the technology that you use</b> and <b>contact me at <u>dmorissette@mapgears.com</u> to confirm your sponsorship</b>. In addition to visibility in our public announcements you will get recognition for your contribution from the developers and from the OSGeo community.<br />
<br />
Please also keep in mind that all the participants are volunteering several days of their time in addition to paying for their own travel and hotel expenses.<br />
<br />

Yes, time is flying! It's only two weeks away! All the pieces are coming together smoothly for a very exciting <a href="http://wiki.osgeo.org/wiki/Montreal_Code_Sprint_2011">OSGeo Code Sprint in Montreal</a> the week of March 15 to 18, 2011.<br />
<br />
As I am writing this, 27 OSGeo project developers and contributors from North America and Europe have signed up to meet and work on <a href="http://mapserver.org/">MapServer</a>, <a href="http://gdal.org/">GDAL/OGR</a>, <a href="http://postgis.org/">PostGIS</a>, <a href="http://liblas.org/">libLAS</a>, <a href="http://www.zoo-project.org/">ZOO Project</a>, <a href="http://tinyows.org/">TinyOWS</a>, <a href="http://geoprisma.org/">GeoPrisma</a>, <a href="http://openlayers.org/">OpenLayers</a> and <a href="http://www.geoext.org/">GeoExt</a>.<br />
<br />
Most of the attendees are from the C Tribe this year, and unfortunately the Java and JavaScript Tribes are essentially missing after making a great presence last year. Come on guys, it's been great to sprint with you last year and we'd like to have you back!<br />
<br />

And also big thanks to the <a href="http://cmm.qc.ca/">Communauté Métropolitaine de Montréal (CMM)</a> for hosting us in their wonderful conference room and providing internet access for free. I'm sure the sprinters will appreciate the view of the city from the 24th floor!<br />

Yes, it's been 5 years already since the creation of the <a href="http://www.osgeo.org/">Open Source GeoSpatial Foundation</a>: OSGeo was born in a meeting that took place in <a href="http://www.osgeo.org/content/news/news_archive/open_source_geospatial_foundation_initial_press_release.html.html">Chicago on February 4th, 2006</a>.<br />
<br />
To celebrate this event, OSGeo's Executive Director Tyler Mitchell cooked us the <a href="http://www.theoworlds.com/birthday/index.php?CardID=146004">birthday cake</a> that you see here on the right!<br />
<br />
OSGeo as we know it today may be 5 years old, but the Open Source Geospatial community itself has been active <a href="http://wiki.osgeo.org/wiki/Open_Source_GIS_History">for much longer</a>. The oldest OSGeo project, GRASS, goes back to 1982, MapServer started around 1995, GDAL/OGR in 1998, and since then the number of projects and community members has been growing exponentially.<br />
<br />
Here are a few highlights of the last 5 years since the creation of the Foundation:<br />
<ul><li>OSGeo went from 8 founding projects in 2006 to 20 software projects today (including 6 in incubation)</li>
<li>OSGeo's annual <a href="http://foss4g.org/">FOSS4G</a> conference turned into a truly international event, visiting 4 continents over 5 years</li>
<li>Over 20 <a href="http://www.osgeo.org/content/chapters/index.html">local chapters</a> are active around the world, promoting OSGeo's software and mission in their local language and communities.</li>
</ul>Closer to us here, the <a href="http://quebec.osgeo.org/">OSGeo-Quebec</a> local chapter was created in 2008, and over the course of those 2.5 years, we have:<br />
<ul><li>held our first local OSGeo conference: <a href="http://rendez-vous-osgeo-qc.org/">Rendez-vous OSGeo-Qc</a> in June 2010</li>
<li>participated with open source tracks and presentations in several geomatics conferences around the province</li>
<li>continued to hold regular events (mostly 5 à 7) around the province, the next dates are:</li>
<ul><li>Quebec City, February 16, 2011: Joint OSGeo-Qc/APELLQc 5 à 7 following the first <a href="http://opencampqc.com/">OpenCamp Qc</a></li>
<li>Montreal, March 14, 2011: OSGeo-Qc 5 à 7 before the Montreal Code Sprint</li>
<li>Montreal, March 15-18, 2011: <a href="http://wiki.osgeo.org/wiki/Montreal_Code_Sprint_2011">OSGeo Montreal Code Sprint 2011</a></li>
</ul></ul>There would be lots more to talk about, but it's time to have a piece of cake.

Each year, over 20 OSGeo project developers and contributors meet for 4 days to work face to face on advancing their software projects. The first North-American sprint took place in <a href="http://wiki.osgeo.org/wiki/Toronto_Code_Sprint_2009">Toronto in March 2009</a>, the second was in <a href="http://wiki.osgeo.org/wiki/New_York_Code_Sprint_2010">New-York in February 2010</a>, and it will be in <a href="http://wiki.osgeo.org/wiki/Montreal_Code_Sprint_2011">Montréal for 2011</a>.<br />
<br />
Here is what we are looking for:<br />
<ul><li>Room(s) with working space (tables and chairs) to comfortably accommodate between 20 and 40 developers. Everyone brings their own laptop, so no computer/workstation is required</li>
<li>Fast and reliable Internet connection</li>
<li>Availability for 4 consecutive days over a weekend, sometimes between January and March 2011 (e.g. Friday to Monday, Saturday to Tuesday, etc.)</li>
<li>Location within walking distance of restaurants and hotels, and easy to get to from the airport by shuttle or taxi since several participants will be flying in.</li>
</ul>If you know of a company, organization, university or college with space that could suit our needs, then please contact me with all the information via email at <a href="mailto:dmorissette@mapgears.com">dmorissette@mapgears.com</a>. Even if you are not 100% sure about the availability of a given option, please do not hesitate to forward your suggestion with a contact name as soon as possible so that we can consider it in our planning.<br />
<br />
We can offer visibility or pay a reasonable fee in exchange for the use of the space.<br />
<br />
Please forward this request through your network of contacts...<br />

<br />
This morning, <a href="http://mapserver.org/">MapServer</a> 5.6.4 and 4.10.6 have been released with some important security fixes. Even if we are not aware of any exploit for the issues, all users are strongly advised to upgrade. All the details are available in the <a href="http://lists.osgeo.org/pipermail/mapserver-users/2010-July/066052.html">release announcement</a>.<br />
<br />
In the last couple of years, MapServer has started to attract the attention of security-aware organizations who have performed audits of the source code. These audits sometimes lead to potential vulnerability reports and security releases like what happened this morning, but there is more to this...<br />
<br />
I like to think of the increasing number of MapServer source code audits as a good thing for a few reasons:<br />
<ul><li>First this confirms that MapServer has hit the critical mass required to attract the attention of groups large enough to afford security audits. It's always good to hear that your software is widely used and getting attention from the Big Guys.</li>
<li>Thanks to MapServer's open source nature, security experts can perform quality assurance on its source code and share their findings and recommendations with us, this of course leads to better software for the users, but also means that we as developers can learn a lot from their reports and get better at writing secure code over time.</li>
<li>All this comes at no direct cost for us. That's open source at its best: those audits are contributions to the project by the users themselves.</li>
</ul>In the end, MapServer wins by becoming more robust and secure, and we as developers get to improve our skills and to learn from security experts. That all sounds great to me!<br />
<br />
P.S. In addition to the potential vulnerability fixes that were released this morning, the last security audit report that we received also contained some more general recommendations that we will be working on in the next few weeks. So you can expect that MapServer 6.0 will be an even more secure release!Daniel Morissettehttp://www.blogger.com/profile/00965593668999032765noreply@blogger.com0tag:blogger.com,1999:blog-808053412198379231.post-67176009580847920102010-06-09T18:12:00.004-04:002010-06-09T19:21:49.188-04:00Rendez-vous OSGeo Quebec 2010 is less than a week away!(<a href="http://dmorissette.blogspot.com/2010/06/moins-dune-semaine-avant-le-rendez-vous.html">Version française</a>)<br />

Looking forward to seeing you in June!Daniel Morissettehttp://www.blogger.com/profile/00965593668999032765noreply@blogger.com0tag:blogger.com,1999:blog-808053412198379231.post-75993649714673025432010-03-05T10:43:00.002-05:002010-03-05T10:55:37.098-05:00ESRI publishes its position on open source software(<a href="http://dmorissette.blogspot.com/2010/03/position-officielle-desri-sur-les.html">Version française</a>)<br />
<br />
I just found out that ESRI has published an official position on open source software on its website at <a href="http://esri.com/opensource">http://esri.com/opensource</a> that sounds quite encouraging. (Thanks to <a href="http://emap.wordpress.com/2010/03/05/open-source-at-esri/" title="About Geo-Infomatic by PK » osgeo">Chaipat Nengcomma</a>'s blog post that I could not read but that hinted me to this.)<br />
<br />
There is also an <a href="http://www.esri.com/news/podcasts/podcast.html?podcast=/news/podcasts/audio/speaker/staff_kouyoumjian.mp3">interesting podcast</a> where Victoria Kouyoumjian (ESRI IT strategy architect) "<i>discusses ESRI’s position on open source and the importance of open source software in GIS application development</i>" (quoting <a href="http://www.esri.com/news/podcasts/speaker_series.html">their own summary</a>).<br />
<br />
We already knew that ESRI had been using <a href="http://gdal.org/">GDAL</a> for some time, had integrated support for <a href="http://postgis.refractions.net/">PostGIS</a> in SDE more recently and even sponsored <a href="http://2007.foss4g.org/">FOSS4G 2007</a>, but to find an official statement of their position is definitely encouraging. I even dare to dream of collaboration between ESRI people and other OSGeo projects in the not too distant future (gotta be optimistic).<br />
<br />
I know (for having been through this myself a few years ago) that ESRI has not always had only good words for people who made the choice of open source software for their projects in the past. Let's hope this position is sincere and will propagate across the whole organisation, and that things will really change and lead to a spirit of real collaboration, for the benefit of all the neo-geographers who want the best of both worlds.Daniel Morissettehttp://www.blogger.com/profile/00965593668999032765noreply@blogger.com1tag:blogger.com,1999:blog-808053412198379231.post-44330354127256518902010-02-26T09:08:00.005-05:002010-02-26T16:31:15.053-05:00OSGeo4W and MapServer Translations(<a href="http://dmorissette.blogspot.com/2010/02/traductions-de-osgeo4w-et-mapserver.html">Version française</a>)<br />
<br />
I am very happy to notice a flurry of translation work going on around the <a href="http://trac.osgeo.org/osgeo4w/">OSGeo4W</a> and <a href="http://mapserver.org/">MapServer</a> projects recently!<br />
<br />
On the MapServer front, <a href="http://twitter.com/mapwebbing/">Lars Lingner</a> started a German translation of the website about a year ago, which led to some work on the website structure to support multiple languages, and a first release of the <a href="http://mapserver.org/de/">German translation</a> on the mapserver.org website a few weeks ago.<br />
<br />
Since then, <a href="http://twitter.com/yecarrillo">Eduin Carillo</a> and Juanma M. R. have started with the Spanish translation, and a few days ago, <a href="http://yjacolin.gloobe.org/">Yves Jacolin</a> volunteered to work on the French translation. I should add that Yves already offers a good number of French translations through <a href="http://softlibre.gloobe.org/">his website for MapServer, GDAL, QGIS, GRASS, etc.</a> The Spanish and French versions of the MapServer website are not published yet, but we can expect them to go live in the near future.<br />
<br />
On the OSGeo4W front, the translation effort started with a Japanese translation of the installer by <a href="http://twitter.com/mapserving">Jeff McKenna</a> and a team of partners in Japan. This required a good amount of ground work to allow support for multiple languages in the installer and the website, and now that the bases are there with the<a href="http://trac.osgeo.org/osgeo4w/wiki/OSGeo4W_jp"> Japanese translation</a>, Yves Jacolin just showed up again to drop <a href="http://trac.osgeo.org/osgeo4w/wiki/OSGeo4W_fr">some French bits</a>.<br />
<br />
Thanks to all the translation contributors for their hard work. If you are interested in contributing to those translation efforts please do not hesitate to join the fun, here are some guidelines <a href="http://trac.osgeo.org/mapserver/wiki/DocumentationTranslation">for MapServer</a> and <a href="http://trac.osgeo.org/osgeo4w/wiki/InstallerTranslation">for OSGeo4W</a>. In all cases, the developers list of your favorite project is the best place to share your intentions and/or ask for help getting started.<br />
<br />
<i><b>Update:</b> Thomas Gratier <a href="http://lists.osgeo.org/pipermail/mapserver-dev/2010-February/009763.html">just announced</a> on mapserver-dev his plan to contribute to the French translation of MapServer docs.

<blockquote><i>(noun)</i> A property referring to the ability of diverse systems and organizations to work together (inter-operate) <i>in a sprint environment.</i></blockquote>We had a great example of this today at the <a href="http://dmorissette.blogspot.com/2010/02/osgeo-code-sprint-2010-in-new-york.html">NYC Code Sprint</a> when members of the <a href="http://geoserver.org/">GeoServer</a>, <a href="http://mapserver.org/">MapServer</a> and <a href="http://openlayers.org/">OpenLayers</a> teams worked together on the simple (but cool) addition of a vendor-specific ANGLE GetMap parameter in MapServer and GeoServer's respective WMS interfaces, and used OpenLayers to test the new feature.<br />
<br />
The result, a few minutes later, was this:<br />

<br />
In addition to the MapServer <a href="http://trac.osgeo.org/mapserver/wiki/60ReleasePlan">6.0 release plan</a> discussions (brainstorming) that he already mentioned, I have been involved in several discussions here and there about MapServer and GDAL/OGR.<br />
<br />
One of the main coding tasks for me yesterday was the extraction of the OGRSpatialReference code from GDAL/OGR into a <a href="http://svn.osgeo.org/gdal/sandbox/libosr/">standalone libOSR package</a> that currently sits in a sandbox in GDAL's SVN repository. This libOSR package will be useful to libLAS, PostGIS, and other packages that need SRS conversion utilities but don't want to carry a complete copy of the GDAL library.<br />

On the menu for me today: some experiments to support on-the-fly conversion of XML mapfiles to text mapfiles inside MapServer using the XSLT, and then possibly start looking into SVG symbol support.Daniel Morissettehttp://www.blogger.com/profile/00965593668999032765noreply@blogger.com1tag:blogger.com,1999:blog-808053412198379231.post-678341260383032162010-02-16T23:16:00.004-05:002010-02-16T23:41:25.311-05:00Rendez-vous OSGeo Québec 2010 in Saguenay(<a href="http://dmorissette.blogspot.com/2010/02/le-rendez-vous-osgeo-quebec-2010.html">Version Française</a>)<br />
<br />
The Quebec Local Chapter of OSGeo is proud to announce the first edition of <a href="http://rendez-vous-osgeo-qc.org/2010/">Rendez-vous OSGeo Québec</a> which is going to take place in Saguenay (a.k.a. Chicoutimi, my home town) on June 15-16, 2010.<br />
<br />
The date of the event also coincides with the second anniversary of the local chapter which was created following a meeting at the same location in June of 2008. A very dynamic community has built around the <a href="http://wiki.osgeo.org/wiki/Quebec">OSGeo Quebec Local Chapter</a> since its creation 2 years ago and I feel that it's just the beginning.<br />
<br />
Members of the local OSGeo community will be invited to present their projects, and we will also be honored to have some of the key players of the North American OSGeo community with us, including (in alphabetical order):<br />
<ul><li>Steve Lime</li>
<li>Jeff McKenna</li>
<li>Tyler Mitchell</li>
<li>Paul Ramsey</li>
<li>Frank Warmerdam</li>
</ul>This will of course be an exceptional chance for the local community members to meet and interact with them, but I must admit that their presence will also be a big highlight for me personally since I have worked with all of them over the years, and I will finally have a chance to show them our <a href="http://www.ville.saguenay.qc.ca/tourisme/index.php?lang=en">very beautiful region</a> and to let them witness by themselves the exceptional dynamism of the local OSGeo community.<br />
<br />
All the ingredients are there for a great <strike>party</strike>event and I hope some of you from the international OSGeo community can join us in Saguenay in June. If you are interested in finding out more, please visit the <a href="http://rendez-vous-osgeo-qc.org/2010/">Rendez-vous OSGeo Québec 2010</a> website (in French only at the moment unfortunately) and come back often to catch updates to the conference and social program.

<br />
OSGeo's <a href="http://wiki.osgeo.org/wiki/New_York_Code_Sprint_2010">New York Code Sprint 2010</a> is approaching fast. Planned by <a href="http://blog.cleverelephant.ca/2010/01/new-york-code-sprint-2010.html">Paul Ramsey</a>, the event will take place from February 20th to 23rd in OpenGeo's offices. Twenty developers will be getting together for four days to work on their favorite projects, including (but not limited to) <a href="http://mapserver.org/">MapServer</a>, <a href="http://postgis.refractions.net/">PostGIS</a>, <a href="http://gdal.org/">GDAL/OGR</a>, <a href="http://liblas.org/">libLAS</a> and <a href="http://openlayers.org/">OpenLayers</a>.<br />
<br />
I'll be there with Alan Boudreault for Mapgears and we plan to work on MapServer. See <a href="http://wiki.osgeo.org/wiki/New_York_Code_Sprint_2010_Agenda">the wiki</a> for an overview of what each project team is planning to achieve. If time permits, I may also post some updates live from the event through this blog.<br />
<br />
Those who cannot make it to New York City are invited to join the event on IRC channel #tosprint (on irc.freenode.net). Cheers to Anton Patrushev and Daniel Kastl (pgRouting), as well as Jeff McKenna (MapServer, MS4W), who plan to join the group via IRC directly from Japan.<br />
<br />

<br />
In a discussion about <a href="http://mapserver.org/mapscript/php/index.html">PHP MapScript</a> on the #mapserver IRC channel yesterday, <a href="http://twitter.com/mapserving">Jeff McKenna</a> pointed out that the PHP MapScript module must be about 10 years old.<br />
<br />
He was indeed right. After a quick lookup of the mapserver-users list archives we found that my first post about what was about to become PHP MapScript was <a href="http://lists.osgeo.org/pipermail/mapserver-users/2000-January/027672.html">sent on January 26, 2000</a>, exactly 10 years ago to the day. Development of the module started in the following weeks and it became <a href="http://lists.osgeo.org/pipermail/mapserver-users/2000-May/028088.html">available to users in May</a>.<br />
<br />
This prompted me to dig out my very first post to the mapserver-users list, which was sent a few hours after I found and fell in love with the software. That was on January 11, 2000, and the title of the message sums it up well: "<a href="http://lists.osgeo.org/pipermail/mapserver-users/2000-January/027641.html">Wow!</a>". After this it didn't take long for us at <a href="http://www.dmsolutions.ca/">DM Solutions</a> to decide to adopt MapServer as our web mapping platform of choice and to start developing and promoting it to our clients.<br />
<br />
Here is another bit of history to put this all in context. At the time, the DM Solutions team had been in the business of building web mapping sites for its clients using proprietary packages since 1998. After almost two years of frustrations, fighting bugs and limitations in expensive proprietary black boxes, we decided that it was time to switch to a more open web mapping platform. We had all the open source components and expertise required to build our own (<a href="http://www.gdal.org/">GDAL/OGR</a>, <a href="http://www.libgd.org/">GD</a>, <a href="http://maptools.org/owtchart/">OWT libs</a>), but before reinventing the wheel I figured I'd do a bit of research.<br />
<br />
On January 4, 2000 I posted our wish list for a Web Mapping Engine to the (now defunct) GIS-L list. I got responses pointing to several packages, but none of them met all our requirements, especially the points about open system and multi-platform support. Of course our list was ambitious, but none of what we asked for was impossible, it's just that no single vendor had done it all.<br />
<br />
The reason for my excitement after finding <a href="http://mapserver.org/">MapServer</a> a few days later was that I could see the potential from day one. The MapServer project was started by Steve Lime about 5 years earlier, it already met many of our requirements, and I knew that given its solid bases and open source nature the missing pieces could be added over time. <br />
<br />
Hats off to Steve Lime for building such a great system, and for being such a great guy to work with. In the years that followed, all the missing bits from our original wish list were added, and the project and its team grew in size and maturity. More on this in a future post I guess.<br />
<br />
Here you go... now you know how I got involved in MapServer, exactly 10 years ago, and the fun continues today.Daniel Morissettehttp://www.blogger.com/profile/00965593668999032765noreply@blogger.com1tag:blogger.com,1999:blog-808053412198379231.post-41815750362247706652009-12-09T22:39:00.004-05:002010-01-27T11:39:23.934-05:00Welcome to Geo Gears, Nuts & Bolts!(<a href="/2009/12/bienvenue-sur-geo-gears-nuts-bolts.html">Version Française</a>)<br />
<br />
In this blog, I talk about open source geospatial software, cool mapping applications and toys... and anything I might find of interest.<br />
<br />
My name is Daniel Morissette, I am an open source geospatial software developer, mostly interested in webmapping and data access and distribution. I have been an active developer and user of open source geospatial software since 1999 and have led and/or contributed to several open source projects over the years, the two main ones being <a href="http://www.mapserver.org/">MapServer</a> and <a href="http://www.gdal.org/">GDAL/OGR</a>. I am an active member of the <a href="http://www.osgeo.org/">Open Source Geospatial Foundation</a> (OSGeo) and several of my posts will relate to projects and activities of the OSGeo community.<br />
<br />
I also have entrepreneurial tendencies, and after co-founding <a href="http://www.dmsolutions.ca/">DM Solutions Group</a> in 1998, I have been leading <a href="http://www.mapgears.com/">Mapgears</a> since 2006. We are based in Chicoutimi, Quebec and our team provides technical support, training and software development services to users of MapServer and related Open Source Web Mapping technologies. <br />
<br />
This blog is bilingual (English/French), with the English posts targeted at the international geospatial community, and the French ones targeted at the Quebec and to some extents the global Francophone geospatial community. Some posts may be translated and others not, depending on the topic and the target audience.<br />
<br />
I hope you enjoy reading me and look forward to hearing back from you.Daniel Morissettehttp://www.blogger.com/profile/00965593668999032765noreply@blogger.com0
