Evaluation of land use and coverage in the Chico River basin.

Abstract

This study evaluates the differences in estimation of changes in land use and land cover between ESA-CCILC and Landsat products. Digital classification by multispectral analysis is applied to Landsat 5 TM and Landsat 8 OLI images, obtaining land use and cover maps. As a method of comparison, the differences are evaluated with the coverage maps provided by ESA-CCILC and those obtained with Landsat images, and their association with the generation of runoff in the basin. The results of changes in land use and cover diverge between the sources analyzed, so it is important to use data sources with good spatial resolution to discriminate these changes.
