Abstract:
Cerrado is the second largest biome in Brazil. Among the land changes in the Cerrado, over 500,000 km² of the biome have been transformed into cultivated pastures in recent years. Distinguishing the native formations and identifying types of land use and cover in the Cerrado are important tasks for monitoring and protection policy of the biome. Within this context, this work aims at developing a methodology based on remote sensing techniques, to map pasture and native grassland areas in the Brazilian Cerrado. Data related to land use and cover, relief, spectral information from Landsat images and vegetation indices were used to perform the image classification. Decision trees and Support Vector Machines algorithms were used, and the results showed that the analysis and integration of different data sources can aid in the classification process. In order to discriminate areas of cultivated pastures and grassland formations, we obtained accuracies up to 82% in the study area, being able to identify attributes and data required to recognize these areas in the Brazilian Cerrado by remote sensing images.
