Desenvolvimento de plugin para análise multicritério ponderada no QGIS

Abstract

QGIS is an open source software specific for GIS. Besides providing numerous tools and possibilities for dealing with spatialized data, there is the possibility of adding functionality through plugins (small programs within QGIS). These plugins are developed for specific tasks and can be shared with QGIS users, such as the WMCA Plugin, here presented, which stands for Weighted Multi-Criteria Analysis, developed to help the user to generate the results of Weighted Multi-Criteria Analysis. This study aims to describe the creation of the WMCA tool and present its ability to facilitate the mathematical process, with weighting criteria, in generating the products of multicriteria analysis and its consequent dynamism in the production of scenarios. The plugin proved to be efficient in generating the analysis products. It was simple to change the grades and weights of the analyses, so that the analysis outputs could be compared.
