Resumo: | Brazil presents great deficiency in cartographic updating area. Many products are outdated around in 30 years in the several scales. A country that has the continental dimensions as Brazil needs have a solid cartographic base to take important decisions about urban planning and consequenting to administration of the territory. One way of updating the cartographic products is the combined use of remote sensing products and techniques of Digital Processing Images (DPI). Among many DPI tools, the Mathematical Morphology allied to the remote sensing data, is one alternative method used to minimize this problem. For the development of this work three images taken with the Landsat sensor was used, having draining net, as the interest features. In this paper was applied the mathematical morphology theory with the aim of detecting features of interests in the images. All the results obtained are presented and were analyzed. The results are positives and show the potential use of mathematical morphology theory in Cartography.
