INCONSISTÊNCIAS DAS ÁREAS DE PRESERVAÇÃO PERMANENTE DO CADASTRO AMBIENTAL RURAL POR MEIO DA GEOBIA

In Brazil, the rules for exploration and conservation of native vegetation are established in the New Forest Code, the registration of information on rural properties is carried out through the Rural Environmental Registry (CAR). The objective of the study is to develop and evaluate a methodology for mapping the inconsistencies between land cover and land use with Permanent Preservation Areas (APPs) recorded in the CAR. For this, Sentinel 1 and 2A images were used. The optical bands of Sentinel 2A with spatial resolution of 10 m were used in the segmentation process, considering the similarity threshold parameters and Minimum Object Size (TMO). Segmentation with the shortest Euclidean distance (D) was used in the evaluation of the parameters of the Random Forest (RF) method. The standard deviation of the Moment of the Inverse Difference and Variance textures were the most relevant to discriminate the classes of land cover and use. For APPs registered with areas smaller than 1 fiscal module, for a total of 95.96 ha, most were classified as native Field and Forest. In areas between 1 and 2 fiscal modules, total of 119.62 ha, the most prevalent classes were also the native Campo and Mata classes.
