Abstract
The article discusses the potential of spatial analysis supported by geoprocessing to characterize, analyse and indicate potential areas suitable to be specified in the designation of Special Areas of Social Interest - ZEIS in Teresina, Piauí. Among the spatial analyses, the application of the Multi-criteria Analysis model is noteworthy, it requires a clear definition of the objectives and consequently the selection of the main variable components for research, the production of thematic layers that portray the chosen variables, the application of a tenable criterion for assigning weights to the variables, and the calibration and validation of results. Partial analyzes are created regarding the distribution of areas of interest for environmental preservation in Teresina, in order to identify the adequacy of the indication of the delimitation of areas of social interest that do not result in conflicts with environmental value. There are also partial analyses to identify potential areas for occupation and urban expansion, in order to assess the suitability of the areas already defined as ZEIS, the areas recognized as settlements (vilas) and slums (favelas), and also to identify possible new areas for occupation by social housing.
