Formerly these two islands were associated with Anguilla as a British Crown Colony, and were mapped by the Directorate of Overseas Surveys (now Ordnance Survey International (OSI)). Following the formal separation of Anguilla in 1980, St. Kitts and Nevis became independent in 1983, as a sovereign democratic federal state within the British Commonwealth.
St. Kitts (formerly also known as St. Christopher) and Nevis are represented on two 1:25,000 scale sheets of DOS 343, originally entitled Lesser Antilles and published as a three-sheet series which included Anguilla. The first edition was published in 1959-60 based on photography flown in 1946 by the USAAF and in 1956 by Hunting Aerosurveys. The latest editions were revised from 1982 air photography with field revision by the Survey Division, Basseterre. The sheets are in five colors with 50 ft interval contours, and the projection is Transverse Mercator, Clarke 1880 ellipsoid (modified). Edition 5 has the BWI grid, while edition 6 has UTM grid.
Soviet military topographic mapping of St. Kitts and Nevis is available at the following scales: 1:1,000,000 (1 sheet, complete coverage, published in 1966); 1:500,000 (2 sheets, complete coverage, published 1979-1986) and 1:200,000 (2 sheets, complete coverage, published in 1967). These products are available in print, digital raster and digital vector GIS formats from East View Geospatial.
In 1990, a Resource assessment and zoning plan for Nevis was published by the UK Natural Resources Institute (NRI), it includes soil, land use and planning maps.
A 1:50,000 scale map of the two islands (DOS 443) on one sheet was published in 1979 in tourist style with 200 ft contours.
A series of 1:2,500 scale contoured maps was begun in 1982 (DOS 043) and completed in 1986. They cover the coastal areas of St. Kitts (58 sheets) and the main road around Nevis (26 sheets).
