Resumen
The terrain interpretation process takes into account information obtained through parametric methods, together with solid and uniform results in the identification of terrestrial systems. The objective of this work was to analyze the influence of the spatial resolution between the SRTM and Alos PALSAR altimetric data and to promote a comparison between the products generated through the description of the relief of the Mourão River basin. This is done using Qgis 2.18 software. and SPRING 5.5.4. three topographic products were generated: hypsometry, orientation of slopes and slope, three tables were generated from the values of class measures of the products and the same ones were submitted to a statistical analysis. As a result, the thematic maps were obtained where it was possible to make a visual analysis, the differences between the class measures of each product were also found and the values attributed to the pvalue were observed. Through the visual analysis it was possible to find the differences between the produced products, especially when evaluating hypsometric maps and orientation of the slopes.
