Algeria became independent of France in 1962. French colonial
mapping had been carried out by the Institut
Géographique National (IGN), Paris, and its predecessor,
the Société Géographique de l'Armée. This involvement
continued for several years after independence until in 1967,
the Institut National de Cartographie, Algiers, was established
and took over responsibility for mapping. The
current name is Institut National de Cartographie et de
There is a long history of 1:50,000 scale mapping; the oldest
version, Type Algérie Tunisie, published from 1897 was on a
Bonne projection, but after 1942, the French Type 1922 specification
was used, on a Lambert conformal projection. Some
sheets were published in a standard edition printed in five
colors with 20 m contours, and others appeared in a provisional
five-color edition (Edition provisoire). These three versions
together provided complementary cover of much of the
northern part of the country. Sheets in these series use a consecutive numbering system. In
1987, a new 1:50,000 scale series was launched by INC. This
is a six-color edition on the UTM projection, Clarke 1880
ellipsoid, and is intended to produce a national map of consistent
quality. Sheet lines and designations follow the
International map of the World system. This new cartography has
a planned cover of northern Algeria in 507 sheets. These have
10 m or 20 m contours and some sheets are also hill shaded.
Publication has continued steadily through the 1990s and
about 160 sheets have been issued.
1:25,000 scale mapping began in the coastal areas in 1961,
using the specification designated Type 1960. The projection
is UTM, Clarke 1880 ellipsoid. The mapping was
relaunched in 1987 with sheet lines changed to conform to
the IMW system, and each sheet now covers an area of
7' 30"x7' 30". This map is in four colors and has 10 m
interval contours. There is a planned cover of about 900
sheets for northern Algeria, and some 365 sheets have been
An extensive cover of the country has also been achieved at
1:200,000 scale in a series of 242 sheets. This mapping began by the French as Carte d'Afrique and continued
from 1983 by INC as Carte d'Algérie. Another 1:200,000
scale version was published in the Type 1922 specification
in the early 1960s by IGN, Paris, and covered much of the
north of the country in 37 sheets printed in six colors with
50 m contours and hill shading.
Soviet military topographic mapping exists at the following scales: 1:1,000,000 (19 sheets, complete coverage, published 1975-1988);
1:500,000 (54 sheets, complete coverage, published 1970-1986); 1:200,000 (372 sheets, complete coverage, published 1977-1988);
1:100,000 (232 sheets, primarily coastal coverage, published 1973-1986)
and city (1:10,000 to 1:25,000) topographic mapping for the cities of Algiers (El Djazair), Annaba, Constantine and Mers El Kebir, published between 1975 and 1978.
These products are available in print, digital raster and digital vector GIS formats from East View Geospatial.
Some 1:100,000 scale mapping was undertaken in the
1950s, and 88 sheets were published in a four-color edition.
A 1:500,000 scale series in 43 sheets, printed in four to
seven colors with 100 m contours and relief shading was
published between 1961 and 1977. A three-sheet
1:500,000 scale tourist map of northern Algeria has been published by INC. The 1:1,000,000 scale International map
of the World coverage is also complete.
Planimetric mapping of urban areas at 1:5,000 and larger
was undertaken with assistance from the former
The current objectives of the INC are to proceed with the
completion of the 1:50,000 and 1:25,000 scale map series
using classic photogrammetric mapping techniques, and
to use satellite remote sensing techniques in the revision of
1:200,000 scale mapping.
