RESUMO

The objective of this work is to study the B-Spline interpolator and evaluate its capabality to generate Digitais Elevation Models. The study area is localized in the periphery of the city of Belo Horizonte, the principal district of the state of Minas Gerais, This place have been chosen because it had digital format datas, and this made the ground survey more simple. ln the begining, the software was developed in PC computers but after it was necesary to work with VAX computer. Then two kinds of languages were used; C language (for PC s) and FORTRAN language (for VAX). The results were evaluated applying the STATGRAPHICS software, and they are graphicaly presents to be possible a visual analise between the real model and the interpolated model, generating a differnce model.
