AUTOMATIC DELIMITATION OF WATERSHED USING DATA SRTM

摘要

abstract_textpThe adequate delimitation of watersheds is essential to be that the territorial unit for planning and management of water resources. Thus, this work aims to evaluate a methodology for automatic delimitation of drainage basins. The project Shuttle Radar Topographic Mission (SRTM) data were integrated and processed in the Geographic Information System (GIS). The results show values of area compatible to those obtained on the topographic data. So, the automation of delimitation of watersheds, through SRTM data and GIS environment, appears to be advantageous in relation to cost and benefits offered, in addition, permits the standardization of the sketch and minimization of conflicts during fixation of the elementary unit of water resources management./p/abstract_text
