标题：IDENTIFICAÇÃO DA FLORESTA ESTACIONAL DECIDUAL NO VÃO DO PARANÃ, ESTADO DE GOIÁS, A PARTIR DA ANÁLISE DA REFLECTÂNCIA ACUMULADA DE IMAGENS DO SENSOR ETM+/LANDSAT-7
摘要：Nowadays, the areas of Dry Forest in the region of the Vão do Paranã, State of Goiás, Brazil, are very fragmented mainly due to land use activities related to cattle ranching and selective logging. The objective of this work is to identify the possibility of discriminating the Dry Forest in the Vão do Paranã through the spectral analysis of multitemporal Landsat images. The images from April to July, 2001 (from late wet season to early dry season) were converted into land surface reflectances and summed one-by-one (April + May, April + May + June, and April + May + June + July). The results showed an increasing improvement in the Dry Forest identification as more multitemporal images were considered. The distribution map of Dry Forest indicated a total of approximately 190,000 hectares distributed mainly in the northern and central parts of the study area. It was concluded that the technique of cumulative reflectance considered in this study is a promising alternative for improved discrimination of dry forested areas.
