%X The municipality of Alta Floresta Mato Grosso was busy in the 70s, and by human activities led to the change of the native forest of the Amazon forest. Thus it is essential to monitor the situation through the use of geotechnology and scientific studies. The objective of this research was to carry out an environmental analysis of vegetation cover and land use of the watershed Mariana, responsible for municipal water supply, by imaging satellite Landsat 8 by OLI sensor for the year 2016, the date July 31 through path 227 row 067. For the image processing used the ArcGIS software version 10.3 and their respective tools. Performed the composition of the bands 4, 3 and 2 and then selected the limits of the watershed and unsupervised classification started the same, generating 4 classes to be worked. As also produced a map of hydrography and springs and other permanent preservation area classification.Since the city was busy there was less vegetation that had 25.44% of the total area, 21.90% areas of pasture, grazing degrades 28.90% and 23.75% exposed soil. The watershed has a total area of 6,500.25 hectares, containing 85 springs and 924.05 hectares of permanent preservation areas, requiring the recovery of 30.47% that are degraded. It is concluded that to reduce this state of degradation must have environmental awareness, especially by the owners of these areas of APP mainly with the function of protecting the springs and watercourses.
