Geometric principles for constructing radar panoramas of the surface of Venus: Hypsometric features of the Moon and terrestrial planets
The physographic curves of the moon and terrestrial planets, drawn both for the entire surface as a whole and for individual hemispheres, were compared to discover the common consistencies and individual features in the distribution of hypsometric levels. In 1983 to 1984 the automated interplanetary stations (AMS) Venera 15 and 16 made radar maps of the planet Venus. The synthesized images are the basic initial material for photogrammetric and catrographic processing to create maps of the Venus surface. These principles are discussed
Geological-morphological description of the Ishtar Terra (photomap of the Venusian surface sheet B-5)
The main part of the Ishtar Terra east of the Maxwell Montes is covered with systems of areal dislocations of several directions, which are called Parquet. According to the structural patterns these may be divided into: (1) the central stable block; (2) the lesser peripheral blocks separated from the central one by gaps and grabens; (3) the zones of mobilized parquet, whose substance flowed downward at an incline in the directions away from the central block in the form of plastic flows; and (4) the partially parqueted lava sheets. The Maxwell Montes were formed as a result of the collision between the central parquet block and the Lakshmi Planum
Geological-morphological description of the Sedna and Guinevre planitiae on Venus (photomap sheets B-11, B-20, B-21)
Presented are descriptions and maps of the region of Sedna and Guinevra Planitiae--representatives of the largest geological providense on Venus comprised of volcanic rock. Units of different age are isolated and their relations are given, as well as interpretations of proposed mechanisms of formation
