Prior to 1965 mapping of the island of Singapore was carried
out by British and Malay agencies, but after independence
responsibility passed to local organizations. Topographic and
aerial photographic surveys are carried out by the Mapping
Unit (SMU), part of the Ministry of Defence, which acts as
the island's national mapping agency. The Survey
Department (SSD), part of the Ministry of Law, is the
civilian mapping and charting authority. It is responsible for
geodetic triangulation, levelling and cadastral surveying and
The basic scale topographic survey of Singapore is at 1:5,000,
and a series of 114 line maps gives complete coverage. These
are derived from aerial photographic coverage, and are updated
on a three-yearly cycle. A 1:10,000 scale series (SMU1168)
is a two-color map road map indicating names
of streets and buildings, complete in 24 sheets. The four-color
5 m contoured 1:10,000 scale (SMU10) series is complete in 30 sheets. Cadastral surveys of
Singapore at a scale of 1:1,000 are carried out by the private
sector, coordinated by SSD.
Derived smaller scale mapping includes 1:25,000 coverage,
published as a four-sheet road map and revised to 1997, or
as orthophoto maps revised to 1995, and various single-sheet
1:50,000 scale maps on the Cassini Soldner Rectangular
projection, Everest ellipsoid. (SMU075) is a seven-color topographic
map, last revised in 1993; (SMU1200) is an outline
version of this map.
Soviet military topographic mapping of Singapore is available at the following scales: 1:1,000,000 (1 sheets, complete coverage, published in 1960);
1:500,000 (1 sheets, complete coverage, published in 1961); 1:200,000 (4 sheets, complete coverage, published in 1983) and a city (1:25,000) topographic map of Singapore
published in 1982. These products are available in print, digital raster and digital vector GIS formats from East View Geospatial.
