The national mapping agency in Liberia is the Liberian
Cartographic Service (LCS). This was established in 1951
with American aid and is responsible for geodetic,
photogrammetric, topographic and cartographic surveying
and mapping of the country. Until the 1970s almost all of
the country's topographic and geological mapping was
produced in conjunction with American agencies. A
1:50,000 scale series provides the basic scale for most of
the country. Sheets in the southwest were produced by the
United States Defense Mapping Agency Topographic Center
(now National Imagery and Mapping Agency (NIMA)) in
Series G744. These full-colored contoured maps were on
the Transverse Mercator projection, Clarke 1880 ellipsoid
and were printed with a UTM grid. Further blocks of maps
on the same sheet lines, and projection, but using a six-color
design and based on WGS 1972 ellipsoid, were
produced between 1983 and 1989 by the British Directorate
of Overseas Surveys (DOS), (now Ordnance Survey
International (OSI)). These Series LIB50 sheets extended
coverage to northern, north eastern and other southern areas,
so that 102 out of a potential 160 sheets are now available.
Other DOS mapping was published in the 1980s, as
1:100,000 scale uncontoured dyeline prints covering seven
half-degree quadrangles in the east of the country. Other
smaller scale coverage includes an uncontoured three-color
1:250,000 scale series, showing relief with hill-shading and
published by the United States Geological Survey
Soviet military topographic mapping of Liberia is available at the following scales: 1:1,000,000 (2 sheets, complete coverage, published in 1986);
1:500,000 (5 sheets, complete coverage, published 1984-1985) and 1:200,000 (24 sheets, complete coverage, published in 1985).
These sheets are available in print, digital raster and digital vector GIS formats from East View Geospatial.
