Geoprocessamento aplicado à análise ambiental: caracterização das microbacias hidrográficas do município de Cerro Largo/RS

Abstract

Geographic Information Systems (GIS), year by year, have becoming an indispensable tool in environmental projects which are being developed, because they facilitate identification and visual perception of the characteristics in the field area. Despite its growing importance in use in environmental applications, there still is a huge lack of availability of data on detailed scales. Through its many tools and wide range of applications, geoprocessing, through thematic maps and crossing of information generated, it will help in decision making about these problems. The performance of this study aims to achieve watershed data survey which are under the borders of Cerro Largo/RS, perform area mapping from generated data using geoprocessing techniques and providing results to the academic community and to the civil society in general. To build thematic maps, it was used an open and free GIS, in addition to files in data bases available in digital platforms of public and private initiative. Among formulated conclusions at the end of this work, we can highlight the use of geoprocessing resources to build geospatial data in the city in question has great potential for further application/execution in environmental analyzes.
