Relief mapping by anaglyph method as a subsidy to the environmental planning in the upper course of the Ceroula stream watershed, Campo Grande-MS

This assignment aimed to present the relief mapping by anaglyph method as a subsidy to the environmental planning in the upper course of the Ceroula stream watershed, Campo Grande-MS. Then, mappings were elaborated using the Geographic Information System, especially the geomorphological map with tridimensional images, on a scale of 1:10.000, and fieldwork, where the reambulation of spatialized information in the cartographic documents was carried out and the characterization of three representative points. The anaglyph method proved to be adequate for the photointerpretation of the relief compartments and geomorphological features, in which drainage divide, lightly undulated hills, foodplain and alveoli, headwaters, topographic colo, slope morphologies (concave, convex and rectilinear), valley morphologies (V and flat shaped) and linear erosions (rills, ravines and gullies) were identified. Environmental problems were found at the representative points, such as erosion and removal of original vegetati on for pasture and soybean monoculture, whose land uses have geomorphological constraints, highlighting the importance of relief and environmental planning in the context of decision-making.
