The Lands Department (LD) is responsible for the publication
of all official mapping of Hong Kong.
Within the Lands Department the Survey and Mapping
Office (SMO) is the central authority for all land surveys
and mapping of Hong Kong Island and the New Territories.
Following transfer of sovereignty to China in 1997, Hong
Kong was designated a Special Administrative Region and
was probably the best mapped territory in Asia.
The first modern basic scale mapping was commissioned by
British military authorities in the 1920s and 1930s (one of the
earliest examples of a photogrammetrically derived map
series). GSGS series provided medium scale coverage until the
1960s, and larger scale plane table-based plans mapped Hong
Kong until the advent of photogrammetrically derived new
large scale mapping from the British Directorate of Overseas
Surveys (DOS), now Ordnance Survey International (OSI).
DOS also produced imperial medium scale series.
From the 1:1,000 scale information a range of smaller scale
maps are derived, almost all of which are published with
English and Chinese characters. 1:5,000 scale coverage with
10 m contours in 162 sheet, this series was
converted into a digital specification in the mid-1990s, and
digital 1:5,000 data became available by the end of 1997.
1:10,000 scale street maps have been produced for urban
areas and new towns, and are also available as digital data.
Two 1:15,000 scale special sheets have been photographically
reduced from this source to show street names for Hong
Kong Island, Kowloon, Tsen Wan and Sha Tin. Other street
mapping is colou-printed, such as the regularly revised
1:30,000 scale Hong Kong guide map, and the
atlas Directory of streets and places.
A 1:20,000 scale topographic series in 15 sheets with a separate
legend was completed in 1977. This is printed in five
colors with 20 m contours, and revised on a two to five
year cycle. At
1:50,000 scale there is a two sheet eight-color map,
depicting relief with 50 m contours, hill shading and layer
tinting, which is updated bianually and is also available as
a two-color version. Single-sheet 1:100,000 and 1:200,000
scale maps are regularly updated and are available as topographic
or administrative editions, and a 1:300,000 scale
overview sets Hong Kong into its regional context.
In addition to these topographic maps LD issues a 1:25,000
series of countryside areas, printed double-sided and showing
footpaths and leisure facilities. Small scale thematic maps are
prepared for the Hong Kong annual report and are also available
as separate editions to cover themes such as land use,
geology, climate, communications, environmental protection
Soviet military topographic mapping of Hong Kong is available at the following scales: 1:1,000,000 (2 sheets, complete coverage, published 1984-1985);
1:500,000 (2 sheets, complete coverage, published in 1983); 1:200,000 (2 sheets, complete coverage, published in 1980) and 1:100,000 (5 sheets, complete coverage, published in 1978).
These products are available in print, digital raster and digital vector GIS formats from East View Geospatial.
