'The Tanzania Geographic Information Systems Users Group (TZGISUG) is a semi-formal network of GIS practitioners and users who are either based in or are working on GIS issues related to Tanzania. The purpose of the TZGISUG is to provide a "place" where constituents of the network can share knowledge, information, shapefiles, map examples and generally provide support on a peer-to-peer basis on variety of technical issues.
The group maintains a free, email listserver for communication. You may sign-up and find our more information about this list by going here:

Today I found myself struggling at work. I had to calculate the area of a suggested protected area - land area only. This was in Norway. We have a couple of floating Spatial Analyst licenses at work. Looking for the right tool in ArcGIS toolbox is no fun. If you are not running a cracked version you are often exposed to your inferior license. QGIS saved the day!

QGIS has taken a giant leap forward. This time it is particularly the vector editing tools which the QGIS team has made much better. This and many other changes brings QGIS closer to replace the ArcGIS product from Esri in some cases.

The GSDI Association, along with partners and participants has allocated resources from the U.S. Federal Geographic Data Committee and the GISCorps of URISA to fund a small grant program to support national or sub-national activities that foster partnerships, develop in-country technical capacity, improve data compartibility and access, and increase political support for spatial data infrastructure and earth observations application development. Could this be an opportunity on the Tanzanian Scene?
