Resumen

Researchers and development practitioners in remote mountain areas rely on elevation data to study vegetation dynamics, natural hazards, land use, and other patterns. However, despite advances in technology, accurate digital elevation models (DEMs) with spatial resolution, 30m do not exist for most of the world’s montane regions. We used a low-cost GPS-based protocol to construct a high-resolution (10m) DEM for a rugged, remote mountain site in the northern Peruvian Andes. Elevation data were collected with hand held GPS units and combined with digitized and interpolated points within a Geographic Information System to generate a 10m DEM.
