TEMPORAL ANALYSIS OF LAND USE AND COVER OF RURAL SETTLEMENT FAZENDA DO SALTO - BARRA MANSA, RJ

Abstract

Rural settlements are created to serve the population that needs to settle in a certain area, aiming to find an alternative for their subsistence and survival. The occupation of areas may interfere with the coverage of the soil initially established. The objective of this work was to perform the spatial-temporal analysis of land use and occupation, by means of a supervised classification, considering the period from 1999 to 2016, in Fazenda do Salto Settlement. ArcGIS 10.2.2 and Landsat7 (ETM + sensor) and Landsat8 (OLI sensor) images were used to elaborate the land cover map anduse, with a spatial resolution of 30 meters. Five classes of land cover and use were defined: Forest, Pasture, Degraded Pasture, Burned Pasture and Water. The supervised classification of the images was done through the Maximum Likelihood classifier. The Degraded Pasture class presented an increase in the history of land use and cover, related to the type of inadequate and incipient management adopted in the settlement area. The maintenance of land cover and use for the Pasture class is due to the main activity in the area of the settlement that is the cattle raising
