One of the titles in a series of topographic maps covering much of north-west Africa, produced as part of the IMW* project in 1960’s. Each map covers an area spanning 6° in longitude & 4° in latitude. There is some variation in colouring & the depiction of terrain, but hill-shading, spot heights & contours are used to show the general relief. Additional graphics show features such as dunes, rock outcrops, cliffs, sand areas, escarpments, marshes, seasonal lakes & watercourses, & areas liable to flooding. Bathymetric contours are also included. Communications detail
Includes:: roads, major trails & railways, although there is some inconsistency in colouring & the extent of classification, e.g. not all maps distinguish seasonal roads. On most maps intermediate road distances are indicated on main routes. Symbols show airports, mosques, mines, oil & gas fields, lighthouses, ruins & significant isolated buildings. Administrative boundaries are marked & latitude & longitude lines are drawn at 1° intervals, with further margin ticks at 1’ intervals. The map legend is in French only on some sheets, & in English & French on others.* The International Map of the World was a project conceived in the early 20th century to compile a world map series at 1:1, 000, 000 through the efforts of participating nations. The value of the program has declined since 1970 & the IMW is no longer regarded as an active international series.
