This is a MapWindow
project contained in a
zip archive that allows
you to graphically select the DEMs, landuse, and soil maps that you
need for your location. Just unzip the archive and open
the project file
World_Data_Grids.mwprj in MapWindow.
DEMs for most of the world are available from CGIAR-CSI. The quantity of data for the world is very large, but our geo-processing guide (see the documents page) explains how to select the files you need.
Landuse maps for most of the world are available from WaterBase. They come in the form of zip files containing 1 or more tiles for each continent. They come in two resolutions, the originals at approximately 400 meters (at the equator) and the resampled at 800 meters. The first are a little more accurate but the they take some time to load and minipulate in MapWindow. You may prefer to use the resampled ones at least while you are learning or experimenting.
Soil maps for most of the world are available from WaterBase. They come in the form of zip files containing 1 or more tiles for each continent.
Global weather data is now available from the SWAT website, and WaterBase also offers a special program for detecting and compensating for missing dates in that data. The SWAT data is more extensive than the data previously offered by WaterBase.
Shape files for river basins across the world are available from WaterBase, divided into continents:
