GEOPROCESSING IN DIAGNOSTIC AND PROGNOSTIC OF AREAS OF SPECIAL INTEREST IN THE AREA OF INFLUENCE TRANSMISSION LINES OF CEMIG - A CASE STUDY OF METROPOLITAN AREA IN BELO HORIZONTE - MG - BRASIL

摘要

The study aims at the exploration and optimization of geospatial technologies in the characterization and analysis of the use and occupation of land near transmission lines Cemig's electricity, with a view to identifying areas of priority interest for monitoring the dynamics of occupation and as for the constructionof predictive studies of the possibilities of transformation in these areas. Part of the project actions Geomap, which includes other actions to build detailed databases about the area of transmission lines, the actions reported in this article refer to planning actions on the region of transmission lines. It promotes broad-based structuring of data, with variables that characterize environmental conditions and the anthropogenic land cover in the areas of transmission lines in the metropolitan region of Belo Horizonte, among which we mention the infrastructure, density and type of occupation, topographical conditions, accessibility factors, socio-economic areas of urban expansion, among others. It structures Geographic Information System for queries and spatial analysis. From the collection of data the models identify areas of occurrence of space activities, studies of correlations of variables and combining variables. Apply models of spatial analysis based on Multicriteria methodology for addressing procedures guided by experts (knowledge driven evaluation) and statistical procedures according to the behavior of the data (data driven evaluation), including the Expert System, the Signature and Data Mining (Data Mining). By relying on the study of methodological exploration of multi-criteria analysis aiming to expand its application to the entire state of Minas Gerais, generates four summaries in four different methodological procedures, in order to validate results and identify the procedures less investment in time and operating cost. The results are distribution maps of potential areas of interest to the comments and attention from the company, as well as the characterization of conditions for the use.
