Official mapping of Vietnam is carried out by divisions of
the General Directorate of Land Administration (Tong Cuc
Dia Chin (TCDC)) in Hanoi. In 1997 the Cartographic
Mapping Institute, the Cartographic Publishing House and
the Department of Land Administration Printing Enterprise
merged to form a single mapping body responsible for the
publication of all official mapping of the country and designated
as the Cartographic Publishing House.
The history of official mapping of Vietnam can be traced
back to the foundation of a mapping office in 1899 in Hanoi
by the French. Topographic surveying under French colonial
authorities included a program of 1:100,000 scale
coverage, based upon the Bonne projection, Clarke 1880
ellipsoid, as well as larger scale coverage of some areas.
1:100,000 coverage of most of Indochina was revised in the
early 1950s using aerial photography.
For the 20 year period from 1955 to 1975 Vietnam was
divided. Mapping of South Vietnam was carried out from
the Dalat headquarters of the National Geographic
Directorate, with aid from the American Army Map Service.
Re-triangulation and photogrammetric interpretation of
aerial photography allowed the production of a new 1:50,000 scale
series, using the UTM projection, Everest ellipsoid, and
employing a 15' x 15' sheet format, which was completed
in 1967. During the American Vietnam War picto- and
orthophoto-mapping at larger scales was carried out for many
areas of the country. A 1:250,000 scale series was also
completed and revised, with 16 sheets for each 1:1,000,000
IMW quadrangle. Meanwhile North Vietnam was mapped
according to Russian specifications by the National
Administration of Geodesy and Cartography, with maps
using the Gauss Conformal transverse cylindrical projection,
Krassovsky ellipsoid, and published for the whole of North
Vietnam at scales of 1:50,000, 1:100,000, 1:200,000,
1:500,000 and 1:1,000,000.
Sheets have been revised using satellite imagery, with few changes to specifications, American style mapping continues to be published for southern areas of the country.
A total of 588 1:50,000 scale maps are needed to cover the whole of the unified
Vietnam, 1:100,000 coverage needs 164 sheets and 1:250,000 scale mapping requires 40 sheets.
Soviet military topographic mapping of Vietnam is available at the following scales: 1:1,000,000 (9 sheets, complete coverage, published 1965-1985);
1:500,000 (18 sheets, complete coverage, published 1965-1992); 1:200,000 (89 sheets, complete coverage, published 1965-1983); 1:100,000 (265 sheets, complete coverage,
published 1978-1991) and city (1:10,000) topographic mapping of Da Nang, Haiphong, Hanoi, Hue and Saigon (Ho Chi Minh City) published between 1976 and 1982. These products
are available in print, digital raster and digital vector GIS formats from East View Geospatial.
