Lagoa Mirim, 300km northeast of Montevideo

Slope map derived from multi-scale resampled SRTM elevation

The border between Uruguay and Brazil passes through the lagoon. Multi-scale resampled SRTM topography not only picks out the subtle coastal features, but also shows road embankments and small patches of dense woodland. By comparing this image with a satellite image, you can better see what is creating each feature. Load this 4Mb KMZ in Google Earth to see for yourself.
