ABSTRACT
SRTM data can help scientists better understand the Earth's systems of land, water, air, and life, how they interact, and how they are changing. The objective of this chapter is to obtain SRTM data to perform spatial mapping and determination of slope, aspect and hillshade variables in a rural property in the municipality of Correntina, state of Bahia, Brazil. The terrain slope, aspect and shading variables are determined from active RADAR remote sensing data obtained from the SRTM mission. The digital elevation model was obtained from the AppEEARS platform. The variables slope, aspect, and hillshade are determined. Solved exercises are created for analyzing soil texture data obtained in situ, as well as for performing mapping of soil variables from raster data model. Spectral indices used in monitoring exposed soil, other technologies that can be used in monitoring, radiance paths, and limitations of remote sensing for soil monitoring are presented.
