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.
