Scientific research

In 1939, Vladimir V. Kavrayskiy invented the Kavrayskiy VII projection. [1]

Kavrayskiy VII projection

The Kavrayskiy VII projection is a map projection invented by Soviet cartographer Vladimir V. Kavrayskiy in 1939 for use as a general purpose pseudocylindrical projection. Like the Robinson projection, it is a compromise intended to produce good quality maps with low distortion overall. It scores well in that respect compared to other popular projections, such as the Winkel Tripel, despite straight, evenly spaced parallels and a simple formulation. Regardless, it has not been widely used outside the former Soviet Union.

Kavrayskiy produced a lifetime of scientific works devoted to the solution of navigation problems.

Navigation The process of monitoring and controlling the movement of a craft or vehicle from one place to another

Navigation is a field of study that focuses on the process of monitoring and controlling the movement of a craft or vehicle from one place to another. The field of navigation includes four general categories: land navigation, marine navigation, aeronautic navigation, and space navigation.

Namesakes

Kavrayskiy Hills in the Antarctic are named after him.

The Kavrayskiy Hills are a line of mostly ice-covered coastal hills in Antarctica, rising south of Rennick Bay and along the west side of the lower end of Rennick Glacier. They were charted by the Soviet Antarctic Expedition (1958) and named after Vladimir V. Kavrayskiy, a Soviet geodesist and cartographer.

Antarctic region around the Earths South Pole

The Antarctic is a polar region around the Earth's South Pole, opposite the Arctic region around the North Pole. The Antarctic comprises the continent of Antarctica, the Kerguelen Plateau and other island territories located on the Antarctic Plate or south of the Antarctic Convergence. The Antarctic region includes the ice shelves, waters, and all the island territories in the Southern Ocean situated south of the Antarctic Convergence, a zone approximately 32 to 48 km wide varying in latitude seasonally. The region covers some 20 percent of the Southern Hemisphere, of which 5.5 percent is the surface area of the Antarctic continent itself. All of the land and ice shelves south of 60°S latitude are administered under the Antarctic Treaty System. Biogeographically, the Antarctic ecozone is one of eight ecozones of the Earth's land surface.

A Dobrynya Nikitich class oceanographic research ship has been named after him. [2]

A research vessel is a ship or boat designed, modified, or equipped to carry out research at sea. Research vessels carry out a number of roles. Some of these roles can be combined into a single vessel but others require a dedicated vessel. Due to the demanding nature of the work, research vessels are often constructed around an icebreaker hull, allowing them to operate in polar waters.

For this he took a lot of criticism from the nationalist politicians and parties. Kozyrev had graduated from the Moscow State Institute of International Relations (MGIMO) with a Ph.D. in history before joining the Soviet Ministry of Foreign Affairs in 1974, holding various positions in it before being appointed foreign minister.

Wagner VI projection

Wagner VI is a pseudocylindrical whole Earth map projection. Like the Robinson projection, it is a compromise projection, not having any special attributes other than a pleasing, low distortion appearance. Wagner VI is equivalent to the Kavrayskiy VII horizontally elongated by a factor of ​. This elongation results in proper preservation of shapes near the equator but slightly more distortion overall. The aspect ratio of this projection is 2:1, as formed by the ratio of the equator to the central meridian. This matches the ratio of Earth’s equator to any meridian.

During his father's exile in the 1070s, Yaropolk can be found acting on his father's behalf in an attempt to gain the favor of the German emperors and the papal court of Pope Gregory VII. His father returned to Kiev in 1077 and Yaropolk followed.
