Development of a methodology by the use of GIS, to an industrial district allocation in the district of Arroio do Meio-RS

Abstract

The use of geotechnologies in the process of decision making is becoming an increasingly useful tool for soil use planning, as it allows a faster result with less subjectivity. In this context, this research had the goal of presenting a spatial model for an industrial district site in the district of Arroio do Meio, RS through a Multi-Criteria Evaluation Methodology subsidized by Geographical Information Systems (GIS). Four restrictive criteria were evaluated: Permanent Preservation Areas (APPs), Restricted Use Areas (AUR), native forest and urban areas, and four criteria factors: declivity, water resource distances, highways and soil use and coverage, these last being, with some degree of suitability, graded from 0 (lowest suitability score) to 255 (highest suitability score). As result, a map was obtained with the areas most suitable for implantation, according to the size needed by the enterprise. Key-words: Territorial Planning; Geographical Information Systems; Multiple Criteria Evaluation.
