Description
Summary:The purpose of this study is to delimit and compare the Chingaza Páramo, which is a protected area within a national park, and Rabanal?s Paramo, which is not protected, using satellite images including LANDSAT and a Digital Elevation Model (DEM). These images allow us to establish the limits of the paramo according to various definitions, and to compare these definitions in order to preserve the area known as paramo. The remote Sensing analysis consist of a classification the terrain using training areas that are recognizable in Landsat 7 and Landsat 8 and areas that are supported by the field trip completed in Chingaza?s Paramo. Comparison with established limits defined according to elevation using the DEM show that the official delimitation defined by the Instituto Von Humboldt is narrower than the delimitation by altitude, which indicates that other considerations, aside from altitude, were included in the Humboldt definition, or that their definition may exclude some parts of the paramo ecosystem. The Landsat classification shows that Chingaza?s Paramo land cover is mainly native vegetation, but witin the Rabanal paramo, native vegetation is being lost, mainly due to human activity.
