A utilização do geoprocessamento na elaboração de mapas temáticos para planejamento do ecoturismo

Abstract

The present work used geoprocessing techniques and graphic computation to elaborate thematic maps that can aid in the process of ecological tourism planning. The generated cartographic products were: Base Map, Use of the Earth and Vegetable Covering Map, Steepness Map, Three-dimensional Perspective and Ecological Tourism Map. The Geographic Information System used was (GIS) Idrisi32, the high space resolution image of the satellite Ikonos II and the Global Positioning System (GPS), besides other programs as Carta Linx, Adobe Photoshop7.0, Campeiro5.0 and Corel Draw11. The work was applied in an area of 1600 hectares where the Hill of the Elephant and yours spills are located, in Arroio Grande district, municipality of Santa Maria - RS. It was ended that the making of thematic maps has addition importance for the maintainable development of the ecological tourism. The use of the geoprocessing techniques propitiates the obtaining of necessary information and as it is stored by digital environment can be crossed easily and updated through the access to the Geographical database, generating in that way new information. It was also verified that with the advent of high resolution space images it can elaborate mapping with a larger detailing and by this way to obtain tourist information that before were not possible. It was also noticed that GIS Idrisi32 possesses have some technical limitations referring to the graphic part, image treatment and vectorial digitization, by this reason it becomes necessary the use of other applications as support.
