Alternative titleStudy of the influence of the relief on the terrain surface reflectance through Landsat images
MetadataShow full item record
Presents a study of the spectral response of a specific vegetative cover under the same soil elevation angle, but in different classes of slope, through Landsat transparencies. The site located in the region of Presidente Prudente was studied through topo sheets to define the classes of slope. Densitometric readings were obtained of selected areas, representing the terrain reflectance in different relief conditions. The cluster analysis was used to classify the densitometric data according to the classes of slope. The map of classes of slope/reflectance of the terrain surface showed a high correlation, mainly for the classes A (0-10%) and B (10-20%). -from English summary
