Abstract
Summary
The work is devoted to the quantitative calculation of surface roughness on the basis of SRTM digital elevation models (DEMs) using Python programming language. We used three methods for calculating the surface roughness: standard deviation of elevation, median differential slope and standard deviation of differential slope. We compare the effectiveness of the last two methods for baselines 2 and 8 pixels, the distance between the points 60 and 240 m, respectively. The results of the research are maps of roughness of the Earth's surface on different scales.
