The national mapping agency in Mongolia is the Ulsin Geodezi Zupag Zϋjn Gazar (UGZZG) (State Administration for Geodesy and Cartography), which was established under this name in 1970. Before its creation a number of different agencies had carried out mapping activities. Geodetic control and mapping specifications conform to Soviet standards and were established between 1935 and 1955. Topographic surveys are published on the Gauss conformal cylindrical projection and the Krassovsky ellipsoid.
Soviet military topographic mapping of Mongolia is available at the following scales: 1:1,000,000 (17 sheets, complete coverage, published 1969-1988); 1:500,000 (50 sheets, complete coverage, published 1970-1982); 1:200,000 (340 sheets, complete coverage, published 1970-1992); 1:100,000 (1,128 sheets, complete coverage, published 1969-1994) and city (1:25,000) topographic mapping of Choybalsan (Choibalsan) and Ulaanbaatar published between 1981 and 1982. These products are available in print, digital raster and digital vector GIS formats from East View Geospatial.
Only after the rationalization of surveying and mapping in 1970 were resources shifted into larger scale programs. UGZZG now maintains photogrammetric programs at 1:50,000 scale, which covered 40 percent of the country in 1999, and 1:25,000 scale covering 30 percent. Larger scale programs are in progress for urban areas, with coverage at scales between 1:500 and 1:10,000 scales.
The Institute of Geology of the Mongolian Academy of Sciences, (Geologi Erdes Bajalgijn Hureelen (GEBH)) was established in 1966, and has been involved in the compilation and publication of standard geological series mapping of the country, carried out by the Geological Survey of Mongolia in the Mineral Resources Authority. 144 1:200,000 scale sheets have been published, with 40 1:500,000 and nine 1:1,000,000 scale maps also maintained. Small-scale coverage is available for a number of geological, minerals and tectonic themes. Among recent projects has been the publication of a 15-sheet hydrogeological map of the country at 1:1,000,000 scale, in conjunction with UGZZG, and with the German Bundesanstalt fϋr Geowissenschaften und Rohstoffe (BfGR). In 1996 SPOT Image signed an agreement to establish a national geological and mining information system, in collaboration with the French Bureau de Recherches Géologiques et Minières (BRGM).
Other recent overseas involvement has included a project from the Swedish SSC Satellitbild for 16-class land cover and land use mapping of a block of 35 1:50,000 scale sheets near to Ulaanbaatar, in cooperation with the Mongolian Ministry of Nature and the Environment, which has resulted in the creation of a digital resources database for the area.
UGZZG also publishes small and medium scale mapping and atlases for the education market, and collaborates with other Mongolian official agencies in the publication of thematic maps of the country, notably, 1:1,000,000 scale coverage for seven themes and covering the country in 14 sheets.
In the 1980s the National Atlas was compiled, with assistance from the Soviet Union, and coordinated by the Mongolian Academy of Sciences (Shinzhleh Uhaany Akademi (SUA)). The completed atlas was published in 1990, in Russian or Mongolian language editions, and included 276 thematic map plates.
International Travel Maps (ITM) has compiled a map of the country, and the best available town map of the capital is from the Polish agency BAKS.
