Abstract

Land cover determination is a transcendental factor in the knowledge and understanding of complex spatial dynamics in a specific area, also, they are a basic input in land planning and its natural resources. The purpose of this study was to evaluate the application of four vegetation indices (RATIO, NDVI, NRVI, CTVI) to estimate the land cover present in the middle part of the Combeima river basin by using the maximum likelihood supervised classification method in a high spatial resolution Pleiades image (0,5m). The results showed that the use of the four vegetation indices, as a support to the supervised classification process, showed better values in the thematic quality indexes of interpretation, with the RATIO index being the best performer, increasing Kappa value by 0,24 with respect to the use of the original image bands increasing Kappa value by 0,24 with respect to the use of the original image bands.
