Abstract
The present work aims to calculate the change in coverage in a specific geographic area
and within given time limits, using landsat satellite images. The work employs a methodology that
begins with the download of images, which will be processed with specialized programs such as
Erdas, - Arcgis - ENVI. Subsequently, a supervised classification of these images was carried out
under the GEOBIA object-oriented paradigm in order to characterize the land cover present in
each of the years analyzed. It was found that there was a loss of forest cover of approximately
4.6%, which had a transition to bare soil, and grass had a transition of approximately 21.8% to
bare soil for the years analyzed
