Resumo
It presents a review of the concept of entropy, its applica-tion in the study of relief and a routine for calculating the matrix with different configurations and spatial resolution of the Digital Elevation Model through geoprocessing of resources in order to subsidize the environmental plan-ning. The methodology was to use the formula for calcu-lating the entropy applied to a square matrix of convolu-tion of n x n cells of the DEM, in which a central cell was classified taking into account the likelihood that the same place in the surrounding area by DEM through the service of operations neighborhood developed in the program Ar-cGIS 9.2 through programming in SQL (Structured Query of Language). It included the development and correlation of the letters of hypsometric, slope, curvature of the pro-file and the flat parts. It can perform the calculation of entropy of relief in different configurations and different array of spatial resolutions of the DEM at appropriate fea-tures of the terrain being, the tool developed, ready to be used in the calculation of entropy in other areas for using both curves level or a Digital Elevation Model. Although the letter of entropy was also relevant in the characteri-zation of diversity altimetry, allowing separate areas with different classes of dissection auxiliary in understanding the ways of relief.
