I'm looking for Image datas for East Africa. Specifically for Rwanda. Does anyone know if such data are available at all free? My target is to digitize roads and buildings with the help of image datas.
I am working with Grass GIS. My job is to find small hydro Power sites. I already did that. For these locations special boundary conditions must be accomplish. E.g. Accessibility of a location (maximum distance to roads about 2000 meter) and a maximum distance to the consumer needs to be defined. Because there are no vector datas of buildings and roads, I need the Image Datas to digitize them.

Check out Earth Explorer. You can search many different datasets depending on avaliablity for certian locations.
