Análisis multi-temporal del proceso erosivo mediante imágenes digitales

Abstract

The present work has as objective the study, treatment, evaluation and erosive modeling of the surface that allows the execution of thematic cartography of the area of ​​the municipality of Mosquera. Using satellite imagery of Landsat 7, Landsat 8, Spot and Rapideye. Where image fusion is initially performed, this allows for increasing the spatial resolution of the image by calculating principal component analysis. Then the classification of use and coverings of the soil in images by means of the algorithm of vector support machines is carried out. Finally, the incorporation to a geographic information system (GIS) for the identification, geoprocessing, modeling, analysis of the erosive processes and the generation of the final graphic outputs was carried out. It was found that the model of soil loss through geographic information systems quantifies the location of the erosive process, such as: very severe, severe, moderate or low, the methodology proposed is simple and is a first approximation To the solution of the detection of eroded areas.
