1. Rwanda base image (Hydrosheds version of the SRTM DEM). The background is a false-color Landsat mosaic from 2000. The area of Rwanda is 26,798 km 2, but hydrological modeling requires that all of the land surface that drains into Rwanda, as indicated by the blue line, be included. http://gis.ess.washington.edu/areas/Rwanda/ Spatial approach in Rwanda's Common Framework of Engagement
