dc.descriptionThe objective of this work is to present the methods used and results obtained in the activities of upgrading water resources maps from Mato Grosso do Sul State. The geographic boundaries of the hydrographic sub-basins or Planning and Management Units (UPG) were upgraded using an algorithm based on D8 (Deterministic Eight-neighbor Method) applied to the Digital Elevation Model (DEM) of the State. The digital hydrographic network was corrected and upgraded from medium resolution satellite images CCD/CBERS-2B, at 1:100,000 scale. The results obtained with these activities constitute a significant improvement on the information of water resources available for the State, although some inconsistencies occurred in the Pantanal flatlands, where minimal or nil height changes jeopardized the analysis of water features, as well as the performance of the algorithm to delimit hydrographic basins. The resulting vector dataset of these upgrading activities is available at SISLA (Interactive System for Environmental Licensing Support), a web tool managed by Mato Grosso do Sul State for the evaluation of environmental licesing processes, which will contribute to improve the management of water resources from this State.
