Normalized difference vegetation index of the conservation unit Gama – Cabeça-de-Veado, Brasilia

Abstract

This study was undertaken in the Gama – Cabeça-de-Veado conservation reserve, an area of 23,650 ha in the Federal District of Brazil. A LANDSAT-7 ETM+ image was transformed into NDVI to identify the vegetation density and the antrophic level in seven predefined land use categories in the conservation unit. The diversity index in the classes: forest, savanna, agricultural area, reforested area, field and exposed soil presented values above 2.0, indicating a high spatial diversity in each of the land use categories. These values show the dynamics of the human occupation in the conservation unit.
