Feed #1 foss4G, OpenAerialMap, QGIS & GvSIG,…


– FOSS4G, a major event for the Open Source GIS World. A little review here

– Web services, clouds…but no need to buy a plane to reach them…During FOSS4G, a nice application has been presented implementing WPS (Web Processing Service) through the implementation of ZOO API project. It gives an idea of the dynamics of web GIS applications development and the possibility of realizing some web apps that are similar to desktop ones


– Ok, everybody knows OpenStreetMap but have you ever heard of OpenAerialMap?

– Always about OSM, interesting examples can be found about the use of Open Geo Data for humanitarian goals below: Haïti, Tunisia, Philippines, Japan…

– [in French] If you’re working in an organism that deals with spatial planning, this blog is worth watching.

– It’s been a while since my comparative analysis of QGIS and GvSIG. For something more recent look here:

– Are you a QGIS perfectionnist mapping artist? If yes, have a look here

1st post of the year!

I wish to all of you a happy new year. My best wishes for 2010!
I then want to thank everyone for consulting my blog. It’s a pleasure to share knowledge amongst the OSGeo community.
I hope you have the same pleasure reading this blog that I have while reading other blogs on the web.
The OSGeo world is so active I discover new things every day!

I wrote the first article on the 17th of March 2009.
The post was about the power of an opensource GIS software as QGIS in an organization and announced a content strongly oriented on Open Source Softwares. It was an honor to see this post mentioned on RL D’Hont’s blog, a very popular geo blog.
Since then, I tried to feed my blog regularly, with around 1 post per month.

Though French, I wanted to write this blog in english to allow the great majority of people to access its content, while practicing my english (I don’t have this opportunity in my current job).
I was very surprised to see that people from all around the world consulted datagistips. I must admit I didn’t expect that! That’s one power of the web to make knowledge accessible to every one.

I often like to look at some statistics of consultation. These are the ones from the birth of the blog till now:

Let’s have a closer look:

– The fact that France is at the top is not surprising: some articles are still in french, like the one about spatial data integration that I plan to translate.
– USA and Canada are then on the list, not surprisingly.
The fact that India has counted more visitors that United Kingdom and that it is in the “top 10” quite astonishes me!
– The same for Brazil that counts more visitors than European countries like UK and Belgium.
It reflects a global interest, not restricted to certain parts of the world. It kind of motivates me keeping on publishing.

I still have many ideas about posts that would potentially raise your interest. The use of Business Intelligence in geographical contexts gets more and more famous. I’ll keep on writing some articles about this domain. You’ll find some tips/tutorials about controlling data (quality, etc..), a critical function in all organizations, because it is strategic and time-consuming.
Also, I’m sure you’d like to read articles about Web developing. I’ve got some ideas of posts about programming with OpenLayers, jQuery.

Anyway, whatever you are interested in, if your concerns are about data and GIS, stay tuned!



Talend Case Studies

Talend is a powerful data integration opensource software.
The offical website includes a section with some clear, printscreened tutorials that let you explore the major functionalities.
The PDF documentations: user and components reference guide (in french and english) are really complete.
In the components reference guide, you’ll find scenarios for each component.
Also, some webinars are animated live during which some Talend users from different organizations (public, private) explain how they use Talend. The webinars are still accessible in the webinar archives part.

Like for every software, the best thing is to practice. To approach all the software’s potentials or even to figure out what could be processed, case studies are really helpful. So, it’s a good news Talend published a case studies PDF. You’ll probably find it useful to see how organizations used Talend in some ambitious business intelligence projects where data integration and orchestration were some prerequisites.
