In this context, the analysis presented developed around the estuary of Curimatau river, located in the Eastern coast of Rio Grande do Norte state, integrates information provided by high resolution images of orbital remote sensing (IKONOS II, dated of July of 2003) and images of not-orbital remote sensing (Air photographs of DPU, dated of March of 1997) in a multitemporary perspective, diagnosising patterns of use and occupation, evaluating the main area?s impacts, together with the estuarian region fisiograph of Curimatau river. The use of high resolution images consequently allowed generates a precision cartography, facilitating the quantification of the evolution of the landscape and supporting decisions. Was possible yet, the definition of use areas, conservation areas and preservation areas; that were inserted in the concept of Potentialities: a fundamental element to management of vulnerable areas of the natural point of view. The information provided during the research had been stored in an Enviromental Georreferenced Data Base, constructed under the optics of Geographical Information Systems (GIS), that they facilitate the environment management Through fast access to information. The results were satisfactory, because permits the quantification of evolution of the landscape and the mapping. Beyond the geoenviromental diagnosis, was possible develop maps and matrixes that support the Rio Grande do Norte state costal Management. / As atividades desenvolvidas na zona costeira sempre despertaram o interesse dos pesquisadores, principalmente quando s?o desenvolvidas em ?reas ecologicamente fr?geis, n?o observando os preceitos do desenvolvimento sustentavelmente empreendido. Nesse contexto, a an?lise apresentada neste trabalho, desenvolvido no entorno do estu?rio do rio Curimata?, localizado no litoral Oriental do estado do Rio Grande do Norte, integra informa??es obtidas atrav?s de imagens de alta resolu??o de sensoriamento remoto orbital (IKONOS II, datadas de julho de 2003) e imagens de sensoriamento remoto n?o-orbital (Fotografias A?reas da DPU, datadas de mar?o de 1997) numa perspectiva multitemporal, diagnosticando os padr?es de uso e ocupa??o, avaliando os principais impactos da ?rea, juntamente com a fisiografia da regi?o estuarina do rio Curimata?. A utiliza??o de imagens de alta resolu??o permitiu a gera??o de uma cartografia de precis?o, facilitando a quantifica??o da evolu??o da paisagem e conseq?entemente a tomada de decis?es. Permitiram, ainda, a defini??o de ?reas de uso, ?reas de conserva??o e ?reas de preserva??o; par?metros, estes, inseridos no conceito de Potencialidades; altamente v?lido na gest?o de ?reas vulner?veis do ponto de vista natural. As informa??es obtidas no decorrer da pesquisa foram armazenadas em um Banco de Dados Ambientais Georreferenciados, constru?do sob a ?tica dos Sistemas de Informa??es Geogr?ficas (SIG?s), que facilitam sobremaneira a gest?o ambiental, no sentido de as informa??es poderem ser acessadas de forma r?pida e racional. Os resultados foram bastante satisfat?rios, pois permitiram a quantifica??o da evolu??o da paisagem e o mapeamento preciso das fei??es ocorrentes na ?rea de estudo, tendo sido poss?vel gerar, al?m do diagn?stico geoambiental, matrizes e mapas que auxiliar?o de maneira racional, simples, r?pida e barata o gerenciamento costeiro do estado do Rio Grande do Norte.
