Formerly an overseas province of Portugal, Guinea-Bissau gained independence
in 1973. Mapped by the Portuguese in the 1950s and 1960s, the country was
covered by a 72-sheet 1:50,000 series on a UTM projection
(Hayford International ellipsoid) with 10 m contours. Sheet
lines are based on the International Map of the World
system, with each sheet covering 15 minutes of longitude
by 15 minutes of latitude. After independence, mapping
responsibilities were passed to the Direcçâo de Topografía e
In 1989, a Centro de Cartografia y Teledetecção (CCT)
was established with the intention of making it the national
mapping agency, but its future is heavily dependent on the
availability of foreign aid. A French-sponsored program
to provide SPOT imagery for the production of topographic
maps was to begin in the early 1990s, and the French also
provided 1:30,000 air photo cover of the country. However,
there were insufficient funds to carry these projects through.
