A digital image processing system is used in a study of the relationship between Venus surface heights and roughness which analyzes the Pioneer Venus surface altitude map and rms slope map in m-dkm scale for the Beta and Ishtar regions. To integrate the data obtained, Venera 9 geomorphological analysis results, 10 TV panoramas, and gamma-spectrometric and photometric measurements were used. No strong relationship is found between the roughness of the Venus surface and its altitude or the degree of a regional slope. On Venus, as on the earth, active techtonomagmatic processes may have taken place in recent geological epochs. On Venus, the factors contributing to higher surface roughness on the m-dkm scale are mostly volcanic and tectonic in nature, while those responsible for the smoothing out of the surface are mostly exogenic.
