Definition of Priority Areas for Fitness Use of Land Through the Analysis Multicriteria

Abstract

This paper aims to investigate the suitability of land use in a watershed by using the multicriteria decision analysis processing in a geographic information system (GIS)-15.0 Idrisi Andes. The data selection and acquisition was based in a digital map product adopted in a 1:50000 scale; in a soil use watershed map, and in a Landsat 7 ETM + satellite image. The criteria set was based on some restriction to the farm management: permanent preservation areas, main roads, land use, slope and vegetation cover. This conflict was been resolved by applying the multi-criteria analysis using a weighting procedure such as the analytical hierarchy process (AHP) and the linear weighting combination (FTA), in a GIS processing. The results showed that the environmental shows agricultural and environmental characteristics, mainly due to the large extension of land available for agricultural use.
