Sources of spatial data were used in the regional analysis component of this project consist of digital raster and vector sources, and scanned paper-based maps. The first group include topographic datasets acquired from ASTER (Abrams, et al. 2002) and hole-filled SRTM (Jarvis, et al. 2006), and the second group are vector datasets acquired from Vector Smartmap and derivative datasets (NIMA 1995). Peruvian and Bolivian government maps were scanned from paper, georeferenced, and transformed (IGM 1986;Klinck and Palacios M. 1985;Palacios, et al. 1993) so that all now coincide with the WGS84 datum.
