Uganda is a fairly small country. This map has been resized to fit on the page. If you double click on the map it will grow to fill the screen. Wait - click on it and it will shrink back to the small version. Either way it is not a big country - about 500 kilometres wide, perhaps 600 kilometres from top to bottom.
This map is done in shaded relief with darker colours indicating greater altitude. Uganda appears to be quite flat. The big lake at the bottom is Lake Victoria, altitude around 1200 metres (4000 ft). The Nile flows north from Lake Victoria and the altitude drops gradually to 1000 metres in the north.
The Equator runs just south of Kampala - good thing this is a high plateau. The south west corner is a little higher - 1500 metres - that is where the Gorilla's and Chimpanzees are!
