Abstract:

Digital Landsat data for the Embalse de Tomine portion of the Cuenca Alta del Rio Bogota, Colombia were analyzed using a small interactive microcomputer system IMPAC. Soil erosion within the study region was located and classified according to categories established by CIAF. Results of the digital analysis were then compared with soil erosion maps produced by INDERENA and CIAF. Correlations between the map produced by IMPAC and those produced from extensive field work were good. Based upon this study, it appears that small microcomputer systems are useful for the analysis of erosional features in the landscape. Author
