The Web GIS workshop was organized in a cooperation between Sokoine University of Agriculture (SUA), Tanzania and the University of Hohenheim, Germany. Last week my friend and fellow Soil Scientist Dr. Ludger Herrmann and me met at SUA in Morogoro, Tanzania to jointly lead this 3 day workshop for the Trans-SEC project working on food security in eastern Africa. Ludger had been my boss during my first job from 1998-2000 at the University of Hohenheim, Department of Soil Science and Land Evaluation, but we had not worked together professionally since then.
The long name of Trans-SEC is Innovating Strategies to safeguard Food Security using Technology and Knowledge Transfer. Over the next 3 years I will work together with Ludger and our partners at SUA, a team of scientists lead by professor Siza Tumbo. My role will be to teach and support the team implementing a Web GIS platform (based on Open Source GIS software) for use in the Trans-Sec project and to publish an Atlas of Food security of Tanzania.
During this first workshop participants where introduced to MapServer, OpenLayers and PostGIS and we build some first temporary web maps together on a temporary web server. On the second last day of the workshop the server that was shipped from Hohenheim arrived in Morogoro by bus and was then installed on the last day of our stay at the computing center at SUA with help from the IT department. Ludger and I will return for two more web mapping workshops over the next two years to support the project and its mapping components.

Introduction to gvSIG CE and geo-processing with SEXTANTE
Terra GIS is offering a 4 hours introductory class/hands on workshop about gvSIG CE desktop GIS and Sextante at the WAURISA Conference in Tacoma on Monday May 7th, 2012, 1pm - 5pm.
gvSIG is a powerful desktop GIS system that is known for having a user-friendly interface, being able to access the most common data formats, both vector and raster ones. It features a wide range of tools for working with geographic information (query tools, layout creation, geo-processing, networks, model builder, etc.) and provides excellent cartography and spatial analysis tools, and a wide range of spatial database connectivity. gvSIG CE is the open and international version that has many extensions such Sextante (raster and vector analysis), Raster and Remote sensing, and Network analysis natively integrated.
Preparations and downloads for workshops participants:
workshop data (zipped file, unzip to your hard drive)
Prior to the workshop please download and copy to your system the gvSIG CE software and the workshop data using the links below. Note that Java is needed to run gvSIG and Sextante and is included in the gvSIG CE download for Linux and Windows, but is a separate download for some Mac operating systems .
Update Monday May 7th:

After the geo-processing library Sextante was made available for gvSIG, gvSIG CE, and for ArcGIS, a plugin for QGIS was released by Victor Olaya in cooperation with the QGIS community. Now the Sextante toolbox truly has the potential to become the most comprehensive and widely used GIS geo-processing tool that runs on almost any software platform and in almost any GIS software . Congratulations Victor and QGIS community !
For the plugin a rewrite of Sextante algorithms in python is being developed and will take some time to be completed. Currently the Sextante toolbox in QGIS provides access to Grass, Gdal, LASTtools, Sextante Modeler, OTB tools, R, SAGA, fTools and mmqgis. Lots more to come in the next months !
