Formerly part of French West Africa, Niger became an independent republic in 1960. Topographic survey was undertaken by the French Institut Géographique National (IGN), and its predecessors, and IGN mapping support continued after independence in cooperation with the Service Topographique et du Cadastre, Niamey. The responsible organization in Niger is now the Institut Géographique National du Niger (IGNN). The principal topographic series is at 1:200,000 scale, and this began as a provisional, planimetric map in 1922, but was progressively replaced after 1955 by a four-color Carte régulière, derived from 1950s air photography. The projection is UTM, Clarke 1880 ellipsoid, and contours are at 40 m intervals. There is a complete cover of the country in 119 one-degree sheets at this scale, although some sheets of the northern desert areas are still in a provisional format (Fonds topographiques or planimétriques). A new edition of some sheets has appeared since 1982. A limited amount of 1:50,000 scale mapping has been completed, covering the southern areas close to the border, and a small area to the north of, including Agadez. Some sheets are photomaps, and recently a few SPOT image maps (spatiocartes) have been produced. A number of sheets in the east of the country form part of the cross-border Lake Chad Basin Commission series of photomaps produced by the British Directorate of Overseas Surveys (now Ordnance Survey International (OSI)). The Japanese International Co-operation Agency (JICA) provided aid in 1992-95 for the production of 36 1:50,000 scale sheets. Some 1:500,000 scale mapping appeared between 1939 and 1968, but only 12 sheets were published. Soviet military topographic mapping of Niger exists at the following scales: 1:1,000,000 (9 sheets, complete coverage, published 1979-1991); 1:500,000 (29 sheets, complete coverage, published 1977-1988); 1:200,000 (187 sheets, complete coverage, published 1979-1986) and a city (1:10,000) topographic map of Niamey published in 1976. These products are available in print, digital raster and digital vector GIS formats from East View Geospatial.
