Preliminary geological-geotechnical mapping, using geoprocessing thecniques, in the Campos dos Goytacazes county, Rio de Janeiro State

Abstract

Campos dos Goytacazes County is located on the north coast of Rio de Janeiro State. The city of Campos dos Goytacazes was developed on a flooding plain and due to the fragility of the physical environment; the city has been suffering serious environmental problems. The methodology used base in acquisition of data bank, remote sensoring techniques, Field Information and application of SIG ArcGis9. In a first step, the themes geology, pedology and geomorphology units was overlaying, where could obtain a Geological-Geotechnical Units Map, with lowed and elevated units, the which had been defined in accordance with its characteristics. The purpose of this map, as well as the objective of the work is to plan the territory for the future generations
