Data Collection
 
 

For this project, all data I used were from the SIS drive as there were enough layers to suit my project. To find data of Africa in other websites was a hard job because few detailed data for this continent were found. Most data I used were in Idrisi raster format (.rst) while others were in Idrisi vector format (.vct) as I used this GIS program to finish my project. Any layers related to this project are listed as the following:







1.  Elevation and Bathymetry (.rst)
2.  Mean Annual Potential Evapo-transporation (.rst)
3.  Mean Annual Precipitation (.rst)
4.  Mean Annual Temperature (.rst)
5.  African Coastline (.vct)
6.  African Country Boundaries (.vct)
7.  Soil Texture (.rst)
8.  Percentage of Surface Water (.rst)
9.  Severity of Water Erosion (.rst)
10. Severity of Wind Effects on the Soil (.rst)
