Técnicas de geoprocessamento aplicadas ao georreferenciamento de imóveis rurais e a delimitação de áreas de preservação permanente e reserva legal em pequenas propriedades rurais

Abstract

The GIS is a set of technologies and techniques that have been widely disseminated and in a multidisciplinary way. In agriculture, among other ways, the GIS can be used with GPS and Geographic Information Systems – GIS, which incorporate functions of spatial databases and conventional computer systems and other ancillary programs such as precision agriculture, geostatistics, and geographic data available on the internet. In this work we applied different techniques of GIS in Site Amabílio Grandfhater, in the town of St. Therese, District of Palma, Santa Maria-RS in order to facilitate the Administration, providing conditions for optimization of the process of georeferencing small farms and provide important information about the area with coordinates from vertices easily accessible location and boundaries of the property, thus serving Law 4771 of September 15, 1965, and the Law 10267 of 28 August 2001 and Decree 4449 of 30 October, 2002. The stages of the work included a survey of the area with GPS, thematic mapping and surveying of relief and general information about the area. Also proceeded to the spatialization of the legal reserve and the area permanent preservation, through techniques georeferenced. Data were integrated into the ArcView application, allowing the generation of thematic maps of the study area, involving the areas of pasture, native and exotic vegetation, area of permanent conservation reserve, crops and water resources. With the establishment of the database was possible to run tests in order to provide relevant information about the area, with regard to crop yields, areas of permanent preservation and legal reserve area.
