GTOPO30 DEMs and Digital Chart of the World (and V-Map0) is, I believe, the
most detailed data you will find in the public domain for these South
American countries. If this is not sufficient, you could try contacting the
national mapping agencies of each country. They would perhaps be sympathetic
to academic work concerning their nations.
