Formerly a colony of France, Guinea became an independent
republic in 1958. It was mapped during the 1950s by the
French Institut Géographique National (IGN) who by
1957 had completed a 1:200,000 scale cover in 34 sheets.
These one-degree sheets were issued as a Carte Régulière in the
north and east of the country, with 40 m contours. Elsewhere
sheets were not photogrammetrically produced, and exist as
a provisional edition compiled in the 1930s and 1940s. 1:50,000 scale mapping was also
undertaken in the 1950s by IGN, with 85 sheets covering
the west of the country and the area of Fouta Djallon. Maps
are on the UTM projection, Clarke 1880 ellipsoid, and have
20 m interval contours.
After independence, the survey and mapping activities of
IGN ceased, and little progress was made until 1977, when
a technical cooperation agreement with the Japanese
International Co-operation Agency (JICA) resulted in new
aerial photography of the whole country being flown between
1977 and 1979. The Guinean National Geographical Institute
(current name Institut de Topographie et de Cartographie
de Guinée (ITCG)) was established in 1980 to work with
JICA. About 350 1:50,000 scale photomaps were derived
from this photography, with the intention subsequently to
produce conventional line maps to match the specification
of the IGN mapping. Only 16 such sheets were produced
before the agreement with JICA came to an end. Subsequently,
IGN has again supported the mapping of Guinea
through French aid programmes, and further sheets were
published in 1988 and 1991-2.
Soviet military topographic mapping for Guinea exists at the following scales: 1:1,000,000 (5 sheets, complete coverage, published in 1986);
1:500,000 (12 sheets, complete coverage, published 1984-1985); 1:200,000 (52 sheets, complete coverage, published 1983-1985) and a city (1:10,000)
topographic map of Conakry published in 1978. These products are available in paper, digital raster and digital vector GIS formats from East View Geospatial.
