Digital Elevation Model of the Altai Mountains and SAT / Landsat / Santinel / World Imagery ESRI

The presented image is a visualization of a digital elevation model (DEM) of the Altai Mountains and vicinity (Big Altai Mountains, Altai Mts). This is the result of the interpretation of the land surface radar mapping data (Shuttle Radar Topography Mission, SRTM Version 4, 2008) and its subsequent processing using the ArcGIS Desktop v10.3.0. Esri Inc., application tools and also using a graphical editor.

	Comment:
1. The Tavyn-Bogdo-Ola or Altai-Tavyn-Bogd ("Tavan-Bogd-Uul, Tavan-Bogdo-Ula, Tavan-Bogdo-Ola, Tabyn-Bogdo-Ola, Tavyn-Bogdo-Ula"). Highest point: Kiityn peak 4,374 / 4,356 m (China-Mongolia). In addition to it, the peaks have heights: "4,134", "4,117", "4,088", "4,073", "4,068", "4,027", "3,922", "3,901", "3,884", "3,789", etc. Tavyn Bogd Uul occupies a cross-border position between Russia, China and Mongolia
2. The largest glacial junction Tavyn-Bogd-Uul, is the most part of the main world watershed of Eurasia, between the Arctic Ocean and the drainless Central Asia. In the west, it passes along the first, high-mountainous border ridge of the Mongolian Altai, separating the rivers of the Irtysh basin and the rivers of the Kobdo and Urunga basins, connected with the drainless lakes of Central Asia. In the north, the watershed runs along the ridges of the Salyugem, Tannu-Ola ridges, along the interfluve of the Muren, Tes, Ider rivers, and further east along the Khangai, Khentei, and Eren-Daban ridges. The massif Tavan-Bogdo-Uul, is a sublatitudinal ridge located at the junction of the Southern Altai, Sailyugem and Mongolian Altai ranges and intramontane basins in the south of the Ukok plateau.
3. The large glacial cluster includes more than 60 glaciers, including the largest glaciers in area: Potanin, Granet, Kozlova - located on the territory of Mongolia; Halasi (Przhevalsky) - on the territory of China; the Argamdzhi group of glaciers - on the territory of Russia. The largest glacier of the massif is the Potanin glacier (Potanins-Mussen-Gol and Alexandra glacier), its area is 38,5 sq. km and a length of 11,5 km. The total glaciated area of the entire Tavyn-Bogd-Uul mountain range is more than 200 square kilometers.
Due to differences in the orography of the Tavyn-Bogd-Uul, and the redistribution of sediments, an asymmetry of modern glaciation is observed. Glacier-fed rivers belong to the river basins: Katun, Khovd and Irtysh.

4. World Imagery (ESRI Inc.) provides one meter or better satellite and aerial imagery in many parts of the world and lower resolution satellite imagery worldwide. The map includes 15m TerraColor imagery at small and mid-scales and 2,5m SPOT Imagery for the world.  In other parts of the world, 1 meter resolution imagery is available from GeoEye IKONOS, AeroGRID, and IGN Spain. Additionally, imagery at different resolutions has been contributed by the GIS User Community. When preparing the design of a series of unified images, a scale scale and a circular scale with divisions in degrees were used (MapTools Inc.).
5. Compiled from a variety of sources, including contributions from the GIS User Community, the World Hillshade (Dark) map provides a multi-directional terrain hillshade rendering of 24-meter elevation data globally and 10-meter or better in many parts of the world. Inspired by the legendary Swiss artist, Eduard Imhof, multi-directional hillshade maps present unparalleled views of the world’s mountains, plateaus, valleys and canyons by using an algorithm that computes light source from six different directions (as opposed to one direction in a default hillshade). The result is a stunning visualization in both high slope and expressionless areas. This Dark version of our World Hillshade is especially useful in building maps that provide terrain context while highlighting feature layers and labels.
6. Multispectral images that include data outside the human-visible spectrum provide more complete information about the Earth's surface.
7. Design versions when using methods of analytical shadow relief shading, in combination with different types of hypsometric scales. GIS application tools provide researchers with ample opportunities for their interpretation, visualization, creating a more realistic image of the landscape and maps.
