Development of soil maps and a soil health surveillance system for sub-Saharan Africa
This part of the project includes ~17.5 million sq.km of continental sub-Saharan Africa (SSA) and 591,740 sq.km of Madagascar, giving a total of ~18.1 million sq.km covering 42 countries. The area excludes hot and cold desert regions based on the recently revised Köppen-Geiger climate classification developed at the University of Vienna, as well as non-desert areas of Northern Africa, small island nations, protectorates and national territories.
ASTER Global Digital Elevation Model
The release of the ASTER Global Digital Elevation Model (GDEM) was announced by Japan’s Ministry of Economy, Trade and Industry (METI) and NASA on June 29, 2009. The GDEM is distributed as 1 x 1 degree tiles, and has a spatial resolution of 30 m (i.e. equivalent to Landsat TM and ETM+). The AfSIS team is currently compiling the GDEM for the African continent, and will be running analysis and quality checks on this during the course of the next few weeks.
