If you have ever used GIS data where the borders just don’t match up, I feel your pain. Of course, map accuracy varies greatly, even within a single map, because of distortions due to projection. However, there are options for increasing the accuracy, and especially for making sure that you don’t have gaps or overlaps between countries, states, or counties on your map. So I’ve pulled together some data and used topology rules to generate the most accurate (that I have seen so far online) free GIS data for all of East Africa, as well as for individual countries. These should come in very handy if you are working on maps of local areas along international borders or other projects of that type, as well as if you just need accurate maps for the area as a whole.
