SENSORIAMENTO REMOTO E GEOPROCESSAMENTO APLICADOS AO ZONEAMENTO GEOAMBIENTAL: Bacia Hidrográfica do Açude Camará - PB

Abstract

The diversity of landscapes at the Camará dam hydrographic basin, especially in terms of landforms, soils and pro- duction systems, has lead to the elaboration of this geoenvironmental zoning. Its importance is refl ected in concerns about environmental conservation, socioeconomic development, and preservation of the area’s natural resources in pursuit of sustainable development. This work aimed at creating an updated database and at carrying out a simplifi ed analysis of physiographic attributes, soil, climate, topography and land use by means of geoenvironmental zoning for separating and describing landscape units, their potential and their limitations. This research used a CBERS sa- tellite image and geoprocessing (GIS) techniques from the SPRING program, which formed the groundwork for the descriptive fi eld studies. The information obtained for soil, topography and land use was used for the description of areas prone to environmental degradation. The results obtained for the hydrographic basin led to its division into 19 geoenvironmental units.
