O uso do sensoriamento remoto no mapeamento de áreas de preservação permanente na bacia hidrográfica do Rio Inhaúma PE/AL

The present study has the objective to use the remote sensing in the mapping of permanent preservation areas of the Inhaúma River’s hydrographic basin – PE/AL. The remote sensing offers a greater speed and objectivity in the process because brings a greater number of data for analysis, it can be a basis to current and future planning and provides information to the control and knowledge of the area in question. In the data fomentation was used satellite images obtained by LANDSAT-5 and provided by USGS. The images treatment was made with the software ARCGIS 10.2.2, as well as the altimetric data of ASTER GDEM with resolution of 30 meters. All the data was used with the objective of to extract the greatest number of information for a better understanding of the study object and serves of contribution to the current science’s theoretical framework about the study area.
