Geotecnologias como subsídio para gestão de ambientes costeiros: análise do recuo em falésias/arribas no Estado do Rio Grande do Norte, Brasil, e suas implicações socioambientais

Abstract

In the present work geoprocessing technics were used through digital image processing and multi temporal geographic analysis on a three decade time scale, using remote sensing images of 30 m and 6,5 m of spatial resolution to identify areas which suffered cliffs retreat of the coast of Rio Grande do Norte-Brazil, measure in m² the retreat and loss of initial characteristics of these environments, as well as to identify and analyze the socioenvironmental impacts present. Five cliff areas retreat were found, with set back up to 78,061 m², putting at risk areas of heavy urban occupation, infrastructures facilities and access roads. Such information subsidize coastal management on these environment of the coast of Rio Grande do Norte
