Caracterização do uso e ocupação das terras de áreas com risco à inundação em Cardoso Moreira e Italva, Rio de Janeiro

Abstract

The aim is to verify the efficacy of the use of different remote sensors in the mapping of use and occupation of lands to the total area of the municipalities of Cardoso Moreira and Italva and to the areas prone to flooding in both localities located on the lower course of the Muriaé river Basin, in the Rio de Janeiro State. It was used the Deimos sensor to the mapping of the total area of the municipalities and the RapidEye to the delimitation of the urban areas and those prone to flooding. The use of both sensors enables to distinguish with accuracy the different classes of use and occupation of lands. The cartographic documents are fundamental to the public bodies and Civil Defense in prevention and mitigation of the effects resulting from flooding, both in urban and rural areas in study.
