Avaliação da área de preservação permanente (APP) ao redor do lago da Usina Mourão I utilizando imagens de satélite de alta resolução e o aplicativo SPRING

Abstract

The permanent preservation areas are of great importance for the population, as it has the objective of protect the fauna, flora, soil, courses of water and ensure the gene flow of populations. There are federal laws, state and, municipal that guarantee their maintenance. But because of the extensive Brazilian territory, it is impossible constantly supervise these areas. With this, the geoprocessing of satellite imagery of high resolution brings agility and efficiency in monitoring the use and land cover, being an important tool for supervision of areas of permanent preservation. Therefore, the study was conducted in PPAs situated around the lake of Usina Mourao I, where there is a conflict of interest of the population with government agencies. It aimed to use the geoprocessing and the new Brazilian Forest Code to verification of conformity or nonconformity of the use and land cover of PPAs. It was possible to confirm that many areas are in discordance to the legislation, and that legislation still confused about the PPAs in the surroundings of artificial lakes. Besides being necessary to use the good sense of managers to determine the evacuation of the places.
