This topographic street plan of Dakhla (formerly Villa Cisneros) was published in 1988 by the Direction de la Conservation Foncière et des Travaux Topographiques in Morocco. The contour interval appears to be 1 metre, but is not claimed as such on this ‘épreuve provisoire‘.
TROPICARTA (requires Chomikuj account) has many Moroccan-produced 1:100 000 maps of this former Spanish colony in the Western Sahara. Smaller numbers have been produced by France, Spain, the United States, and the Soviet Union. The author has not seen any topographic maps originating from Algeria.
