Digital Elevation Model of the Altai Mountains, Under khan uul (World Imagery ESRI / WSH / RRIM)

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.

1. The presented image is the result of visualization of digital elevation model (DEM) data on the Under Khan uul (3914,0) bordering China, which is located in the southeast of the Altai Tavyn Bogd National Park.
2. DEM data was processed using ArcGIS Spatial Analyst Tools, ESRI Inc. Three indicators were visualized: angles, depth of dissection, and density of slope dissection. Full color and monochrome versions of the image are shown.	
3. 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.
4. 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.).
