TOPOGRAPHIC MAP
In the early 1980s, the national institute of cartography and remote sensing launched a new program of a basic regular topographic cartography at a 1:50 000 scale. It replaces the old cartography which became obsolete.
The projection system conical lambert was abandoned for the UTM system and for a new installed cutting (geographic).
The photogrammetric restitution from an aerial photography at the scale 1:40 000 allows a detailed and precise surveys for a photography at the scale 1:25 000. It allows too a photographic cover mainly for the coastal area at the scale 1:25 000.

The INCT publishes and commercializes a several series of basic topographic maps and derivatives at different scales.
Two scales are defined for the basic cartography: 1:50 000 for the north and 1:200 000 for the south. The actually limit of 1:50 000 is the parallel 34°.

Topographic map at 1:200 000
NB: the cartographic cover of north at 1:200 000 is a derived cartography. |

The cartogram of the cartography at scale 1:25 000 can be visualized here. |

Topographic map at 1:500 000
NB:/ the sheet map of ADRAR resulting from planimetric outline includes not the altitude. The sheet map of IN Guezzem is edited in black and white |

International map of world at 1:1 000 000
Normal edition in 06 or 07 colours: this edition contains the same elements as the international edition except the hypsometric colour. The road mileage is indicated on red. In the Saharan area, the silted area are represented on yellow. |
