The Zambian national mapping agency the Survey
Department (ZS) is responsible for national topographic
mapping and for cadastral survey. It also publishes small
scale thematic coverage of the country and compiles large
scale township maps and street plans. All maps are on a
Transverse Mercator projection, Clarke 1880 ellipsoid.
The basic scale map for the country is the 1:50,000 scale ZS
51 series. This map was started after World War II by the
British Directorate of Colonial Surveys (later Directorate of
Overseas Survey (DOS) and now Ordnance Survey
International (OSI)). Early sheets had 25 ft or 50 ft contour
intervals or in some areas were issued as preliminary plots
with no relief data. DOS continued to provide aid for the
production of new maps in this series throughout the 1970s
and some current sheets still carry the series designation DOS
424 (Z741). Since 1970 five-color metric editions have been
published by ZS with 20 m contours and the UTM grid.
Details are revised from the latest available aerial photography,
which has often been provided in overseas aid projects,
for example delivered through the Japanese agency JICA, or
the Swedish Swedesurvey. Specification changes include a
move to process colors in the early 1980s. This series covers
most of the country, with the exception of sparsely populated
areas of South Western province. A 1:100,000 scale program
designated ZS 41 is in progress, initiated in 1980
and nearing completion. A 1:250,000 scale map ZS 31 covers
the country in 53 sheets. The current specification is for 50 m
contours and a UTM grid, and most sheets cover one and a
half degrees longitude by one degree latitude.
Other smaller scale national mapping includes 1:750,000
scale relief or land use coverage in four sheets, as well as sheets
conforming to ICAO specifications in a 1:1,000,000 scale
aeronautical series, which is also available in a topographic
edition without the aeronautical overprint. At 1:1,500,000
scale ZS publishes a single sheet map, which is used as a base
for 10 different thematic maps. Most date from the 1980s; the double-sided tourist map
was issued in a new edition in 1994.
Soviet military topographic mapping of Zambia is available at the following scales: 1:1,000,000 (8 sheets, complete coverage, published 1977-1985);
1:500,000 (22 sheets, complete coverage, published 1978-1985); 1:200,000 (134 sheets, complete coverage, published 1979-1984) and city (1:10,000 to 1:25,000)
topographic maps of Lusaka and Ndola published in 1979. These products are available in print, digital raster and digital vector from East View Geospatial.
