标题：INTEGRAÇÃO ENTRE DADOS ÓPTICOS E RADAR (SRTM) PARA A CARACTERIZAÇÃO GEOAMBIENTAL DA COSTA SETENTRIONAL DO RIO GRANDE DO NORTE / RADAR (SRTM) AND OPTICAL DATA COMBINATION FOR GEOENVIRONMENTAL CHARACTERIZATION OF THE RIO GRANDE DO NORTE NOTHERN COAST
摘要：The demand for energetic resources on the country increased the exploration of hydrocarbon andconsequently the risk of oil spill on environmentally sensible areas located on the Rio Grande do Nortenorthern coast. This fact justify the environmental monitoring using remote sensing and environmentalmodeling techniques. The study area extends from São Bento do Norte to Porto do Mangue cities. It isinserted on the geological context of the Potiguar Basin with a high environmental sensitivity index. Themain geoenvironmental units are occupied by industrial activities as salt and oil industries and shrimp farms.This paper aims to describe the integration of radar (SRTM) and optical (LANDSAT 7 ETM+ and CBERS2-CCD) data to create images which enhance geomorphology and morphotectonic features from thearea, allowing a better environmental characterization. Altimetry, lineaments, drainage system and slopeinformation were obtained from SRTM data. RGB color images were created from the optical data withcontrast enhancement. This methodology is useful to support the understanding of the morphodynamicframework, and creating a good cartographic database which can be used on emergency plans on oilspills, and to optimize protections of the most sensitive environments. The results also aid a better planningof new oil exploration areas.
