Determination of the land use of the municipality of Bandeirantes, Paraná State, using Landsat 7 Etm + image and geoprocessing techniques

Abstract

For the agricultural planning of a region, one of the fundamental items is the identification of the installed cultures. The geographic information systems, allied to remote sensing are important tools to the identification and evaluation of the land use. With the objective of identifying the land use of the municipal district of Bandeirantes-PR, it was used the bands 2, 3, 4 and 5 of LANDSAT 7 ETM+, NDVI (reason among bands 4 and 3). The image classification, was accomplished by the classification system supervised for areas, classifier Batha charya, implemented in SPRING 3.6.03, developed by INPE (National Spatial Research Institute) and the colored composition NDVI, 5 and 2 (R,G,B) it contrasts (average: R = 77,72, G = 75,6, B = 50,24). The municipal district land use ponders mainly in annual cultures, pasture and sugar cane, with participation of 27,31%, 20% and 18,31% respectively. The bands composition used was efficient in the determination of the land use, and the division among bands 4 and 3 to obtain NDVI was important, mainly in the areas of more irregular landscape. The geographical information system demonstrated agility and precision in the evaluation of the thematic areas.
