description |
The objective of this project was to apply geographic information system (GIS) technology, mainly ARCGIS and ERDAS software, as a methodology to identify changes in coverage and land usage of the terrain comprising the wetlands La Bolsa, Charco de Oro, and El Pital, located in the flat zone of the Andalucia municipality, in the villages of Campo Alegre and el Salto (Valle del Cauca Department, Colombia). The study employed aerial photos from 1950 and 1998, Landsat images from 2002, and base cartography of the zone. The processes within the methodology were purged. For example, the geo-referencing of photographs, and the creation of photo-mosaics to convey an image with a better visual appearance, and easier identification of the wetlands, in such a way that when making comparisons, they reveal changes in coverage in the study zone. The usage of GIS and correct processing of satellite images will be very helpful not only to evidence changes in soil usage in wetlands, but also in different areas where use of these technologies is very unusual. |

Para el estudio se utilizaron fotografías aéreas de 1950 y 1998, imágenes Landsat 2002 y cartografía base de la zona. Los procesos dentro de la metodología fueron depurados, un ejemplo es la georreferenciacion de las fotografías y la creación de fotomosaicos que conllevan una imagen con mejor apariencia visual y más fácil identificación de los humedales, de manera que al hacer comparaciones, aquellos arrojen cambios de cobertura en la zona de estudio. Así, la utilización de los SIG y un correcto tratamiento de las imágenes satelitales resultan de gran ayuda no sólo en la obtención de los cambios en el uso del suelo y los humedales, sino también en diferentes áreas donde la utilización de esta tecnología es poco común.application/mswordspaUniversidad Nacional de Colombia Sede Palmirahttp://revistas.unal.edu.co/index.php/acta_agronomica/article/view/12541Universidad Nacional de Colombia Revistas electrónicas UN Acta AgronómicaActa AgronómicaNúñez Restrepo, Christian Andrés and Madero Morales, Edgar Enrique (2009) Changes of the coverage of three wetland areas in cauca valley.
