GEOTECHNOLOGIES APPLIED TO TIME-SPACE ANALYSIS OF LAND USE AND OCCUPATION IN COASTAL PLAIN OF CARAVELAS (BA) - DOI 10.5216/bgg.v35i1.35485

Abstract

The objective of this study is Diagnose the main forms of land use and occupation of the Caravelas Coastal Plain over the years 1984, 1991, 2006 and 2011. The study area is the Caravelas Coastal Plain , inserted in the extreme south of Bahia state, occupying an area of 580 km ², located between the parallels 17 ° 37’52 “S and 17 ° 51’44” S and the meridians 39 ° 22’7 “and 12’7 .11 ° 39 ‘W of Greenwich. For this diagnosis was used as basis the satellite images obtained by using LandsatTM subsequently integrated and processed in GIS at ArcGIS software using the hybrid classification. The results obtained confirm the gradual expansion of the agricultural area, urban area and pasture. In parallel the reduction of areas occupied by water bodies, wetlands and mangroves. The mapping
carried out intend to contribute to studies of landscape evolution and support better planning proposals for the use and occupation of land along the Caravelas Coastal Plain .
Key words: use and occupation of the land, hybrid classification, Caravelas, geotechnologies.
