The Cayman Islands are a British dependency, formerly under
the administration of Jamaica. There are three islands in the
group: Grand Cayman, Little Cayman and Cayman Brac.
The Directorate of Overseas Surveys (now Ordnance Survey
International (OSI)) first published a 1:25,000 scale map
(DOS 328) in 1965-6, based on air photography flown
in 1958. Complete air photo cover was again flown in
1970-71, and the 1:25,000 scale sheets were revised and
published in a second edition in 1978 with planimetry
derived from large scale cadastral plans, and swamp vegetation
from an ODA survey carried out in 1976. The 1:25,000
scale map has 20 ft contours, and is on a Transverse Mercator
projection with UTM grid, Clarke 1866 ellipsoid.
In 1979, a single-sheet visitors' map using a photomap base
was issued (DOS 428P). A second edition was revised by
Ordnance Survey from information supplied by the Lands
and Survey Department (LSD), Cayman Islands and
published in 1989. It has an inset map of Georgetown.
Soviet military topographic mapping of the Cayman Islands exists at the following scales: 1:1,000,000 (1 sheet, complete coverage, published in 1963) and
1:500,000 (2 sheets, complete coverage, published in 1983). These products are available in print, digital raster and digital vector GIS formats from
East View Geospatial.
