Decision Support Method Contribution to Generate Interactive Maps of Suggestion for Land Use by Using the Concept of Soft Decision Tree: Case of Island of Sao Francisco do Sul, Brazil

Abstract

This work presents a contribution to the decision support method for planning and administration of land use, with the concept of a soft decision tree. The results are interactive maps of suggestion for land use. The source data are obtained from field surveys and from thematic maps, combined in a geographical information system environment. The data are stored in a geodatabase, and operated by fuzzy logic. The information contained in the geodatabase is managed by a developed interface software that aggregates and analyzes the variables by a soft decision tree, using commercial software. The resulting data are then processed to generate an interactive map of suggestion for land use. The proposed method is validated with the example of an interactive map of suggestion for land use on the island of São Francisco do Sul, southern Brazil.
