|Working with QGIS in a spatial data infrastructure of Jalisco in Mexico|
The Instituto de Información Territorial del Estado de Jalisco is a government organization which was founded in 1998 to share geographical information between the government agencies of Jalisco in México.

Within the years, the institution has gathered loads of information in several formats such as SHP, DWG, DXF, GeoTIFF and ECW, among others. So, what we wanted was to have all this information available, organized and in a common format with the purpose of being able to provide and display it over the Internet.

That's how it was developed the Sistema de Información Territorial Estatal en Línea, with the main target to build a spatial data infrastructure which allows our government agencies to share this kind of information to be included in their own projects as health, security or mobility.
Decision for QGIS
What we use QGIS for
Internally, we use QGIS to check the raster and vector data of the agencies before publishing it, and after its integration, we used it again to test the Web services that we’ve created. Also, we have done many spatial analysis with QGIS pulling the data directly from our PostgreSQL spatial database, then, we export the results as shape files.
