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 Cadastro, Bissau. 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. Soviet military topographic mapping of Guinea-Bissau is available at the following scales: 1:1,000,000 (complete coverage, published in 1986); 1:500,000 (4 sheets, complete coverage, published in 1985) and 1:200,000 (14 sheets, complete coverage, published 1983-1985). These products are available in print, digital raster and digital vector GIS formats from East View Geospatial.
