Figure 1: The most recent and exciting addition to the Los Amigos GIS is shown above in raw format. Mathias Tobler masterminded the conversion of Aster optic imagery to digital elevation model format. We now have a Digital Elevation Model (DEM) for most of the conservation area (red lines). We plan to use the DEM and products displayed in the rest of this photo essay for two primary purposes: (1) to guide Los Amigos Botany and other projects in exploration and monitoring of the conservation area, and (2) to intensively explore the methods of geospatial and information science, using our landscape-scale investigation as a working model.
