Georreferenciamento e elaboração da base cartográfica do Instituto Federal Farroupilha – câmpus Alegrete

Abstract

The Instituto Federal Farroupilha, Câmpus Alegrete, is an educational institution dedicated, among other, to the agricultural area. In addition to teaching, it has productive sectors in agriculture and livestock. With an area of approximately 318 ha, and divided into sectors of cattle, swine, sheep breeding, poultry farming, fruit growing, horticulture and fish farming, has no proper planning and even has tools to do so. A complete cartographic database is a major tool in agricultural management. Based on this, this study aims to carry out the georeferencing of the Instituto Federal Farroupilha area, Câmpus Alegrete and, from this, generate auxiliary maps in agricultural production and management the institution areas. This work was carried out through satellite images georeferencing using geoprocessing techniques applied and the use of topographical equipment in the acquisition of information in the field. In maps preparing was used ArcGis computer software and lifting points to field coordinates, the GPS ProMark 3. Through the precise coordinates of control points, it was possible to georeference the satellite images available for free on Google Earth PRO. The total area maps were generated and property perimeter map of land use, water resources map, map of Permanent Preservation Areas, map of Legal Reserve, the total area map with crops and map with the location of the productive sectors. Then, it was possible to determine the total area of the building, which was 263.95 ha, 17% less than the registration area. The digital cartographic base generated in this work can be used by all sectors, assisting in the management and planning of the institution.
