The national mapping agency in Bahrain is the Survey
Directorate (SD) which was established in the Ministry of
Housing in the late 1970s. The basic topographic mapping
of the state as a whole is a 28-sheet 1:10,000 series on the
UTM projection, International ellipsoid, first compiled in
1977 on a contract with Fairey Surveys, as orthophoto
editions and subsequently revised regularly as a two-color
line map with 2 m and 5 m contours. Intermediate full-color
series were derived from these maps and published
at 1:25,000 scale (seven sheets), and 1:50,000 scale (three
sheets), with single-sheet 1:100,000 and 1:200,000 scale
coverage also being issued. A regular revision program
maintains these maps with a currency of no less than three
years for developed areas of Bahrain.
In the north of the island the developed areas were compiled
as digital mapping in a BKS Surveys contract in the early
1980s and are held in an Intergraph mapping database.
These include 1:1,000 scale coverage in 9,449 sheets, as well
as 220 sheets of a 1:2,000 scale series. The large scale map
database is under constant revision with print on
demand to support a wide variety of official applications
including land registration and transfer and the provision of
Soviet military topographic mapping of Bahrain exists at the following scales: 1:1,000,000 (1 sheet, complete coverage, published in 1983);
1:500,000 (2 sheets, complete coverage, published 1977-1981); 1:200,000 (2 sheets, complete coverage, published in 1977); 1:100,000 (7 sheets, complete coverage, published 1978-1984)
and a city topographic map of Manamamuharraq (Manama, Muharraq) published between 1977 and 1980. These product are available in print, digital raster and digital
vector GIS formats from East View Geospatial.
