Resumo: | In recent period the discussion about the changes and compliance with the Forest Code was highlighted by involving from environmental damage, such as political and economic interests related to the topic. In the context of the revision of the Forestry Code and the use of geotechnology, the objective of this study was to map temporally vegetation in two basins that make up the Paraná River Basin 3 (BP3): the São Francisco River Basin True and the São Francisco River basin False, located in the West of Paraná. The mapping of period was 1973 to 2011, considering the legislation in accordance with the Law 4771/1965 the Forestry Code in order to verify to what extent there has to the compliance of current legislation in the period. Landsat-1 satellite image sensor Multispectral Scanner (MMS) were used for the year 1973, Landsat-5 Thematic Mapper sensor (TM) for the years 1990, 2000-2001 and 2011 and 2011 RapidEye images. The mapping of the temporal distribution of vegetation was obtained from Bhattachatyya classifier through the application SPRING 5.1.8. Then the data was exported to ArcGIS 10.3 application for making the final layout of cartographic products. Through Qgis 2:12 were generated 500 random points for mapping validation of 2011, reporting 87% overall accuracy. From these points, took place the field work, where were visited 31 points classes vegetation and non-vegetation, including the points that had an error on the accuracy of validation. With the temporal mapping associated with the bibliographic study, it was found that the distribution of the study area vegetation was modified due to the devastation that opened the way for agricultural occupation, including by government incentives. However, there was recovery of much of the vegetation cover, mainly the river banks as a result of compliance with Law 4771/1965 |
