Comment:
1. A series of images of the Earth's surface obtained on the basis of satellite data and aerial photography hidrolocical objects of located in Mongolia, in the adjacent territory of Russia and China. The hydrological objects and landforms are given for the Mongolian Altai, the Khangai Highlands, the Khubsugul region, the Great Lakes Basin, and a number of other areas. 
	The objects are landforms created by temporary and permanent streams (Water Hydrology - Channels, Stream, Lake, Drainage Basin, Landforms, Megafloods...). 
General patterns of geological activity can be traced on the shores of lake basins, the structure and features of river valleys. This set of illustrations also includes swamps - waterlogged land areas.
	The main river systems, the Selenge and Kobdo (Khovd), are indicative, as well as the relief forms associated with the geological work of temporary watercourses in arid regions. The steepness of the slopes, seismicity, the work of permanent and temporary watercourses in mountainous arid regions leave clear and characteristic traces. Alluvial cones (fans) can reach an impressive size. These relief forms are associated with the transfer of a significant volume of detrital material, often revealing areas with folded dislocations. The river systems of Mongolia belong to three basins: the Central Asian Internal Drainage Basin, Northern (Arctic) Ocean Basin and the Pacific Ocean Basin.
	The lakes of Mongolia contain over 500 cubic km of water, which is almost 15 times the flow of all rivers in the country. Of interest are objects located on the shores of lakes, in the highland zone of the Mongolian Altai and on the periphery of one of the largest intermountain basins in Central Asia - the Creat Lake Depression, Valley of Lakes, Darkhad Depression. By origin, lake basins are diverse: volcanic, glacial, permafrost, fluvial and deflationary. Where the surface is affected by permafrost processes, the territory has a characteristic appearance. Small landforms - permafrost polygons, structural soils have a regular distribution and regular outlines. An example is cryopolygons in the valleys of many rivers of the Mongolian Altai and Khangai, on the coast of Tolbo Nuur, Baga Nuur, Telmen Nuur, Sangiin-Dalai Nuur, Terkhiin-Tsagaan Nuur and other lakes.
	Control sites on the coast of lakes are given for three altitude intervals: above 2000 meters, above 1000 meters and up to 1000 meters. The numbering of the folder is end-to-end, the absolute height of the plot is indicated in the folder name.

2. 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.

3. World Imagery Clarity is a view of Living Atlas of the World imagery that publishes archived imagery that may be more clear and/or accurate than what is presented in the default.
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.).
