The background is a false-color Landsat mosaic from 2000. The area of Rwanda is 26,798 square kilometers, but hydrological modeling requires that we consider all of the land surface that drains into Rwanda, as indicated by the thick blue line. |
This is the DeLorme background map as distributed by ESRI: |
This is the Hydrosheds SRTM 3" (~90m) DEM. Rwanda elevations run from 914m to 4457m (in our GIS) on Vulcan Karisimbi. |
Most of Rwanda drains into Lake Victoria in the Nile watershed (large green polygon). The western portion drains to Lake Kivu and Lake Tanganyika in the Congo watershed. |
These are the regional rivers, as defined by the HydroSHEDS 15-minute beta dataset. |
This is the Rwanda watershed as abstracted for the VIC model. |
We have TRMM rainfall on a quarter-degree grid at daily (actually 3-hour) intervals. |
This is MODIS satellite land cover.

This is the FAO world soil suborder data: |
This shows contributing area abstracted to the 5-minute (~8 km) cell size at whcih we usually run the VIC hydrologic model. Background includes the SWDB surface water coverage and the HydroSHEDS 15-minute river network, as well as the SRTM -based topography: |
Two ASTER images at the northern edge of Rwanda show 15-meter resolution in the visible and near-infrared. The image on the left is NDVI and the image on the right renders NIR, red and green as RGB. The background is the 2000 Landsat mosaic. |
