Using Geoprocessing to Map Consolidated Urban Areas

The threat to natural resources especially available water resources is a cause for concern. Thus the need arises for studies that address the forms of appropriation of these territorial spaces in order to discipline the activities potentially harmful to the environment and to promote appropriate forms of use of spaces in accordance with their capacity for use. To this end tools are used that can assist in environmental management to promote the improvement of municipal environmental conditions. Within this context the present research aimed to apply the procedures of thematic mapping with the use of Geographic Information System (GIS) at a scale of 1:10000 in order to subsidize the decision making in environmental planning of the Micro Hydrographic Basin of Rio Maior belonging to the Urussanga River Hydrographic Basin located in the extreme south of Santa Catarina.
