Lay of the Land: The National Archives of Singapore’s Map Collection
From Singapore’s days as a colony to modern times, maps have been an integral part of the nation’s development. Kevin Khoo highlights the National Archives of Singapore’s 10,000-strong map collection.
Among the various records under the care of the National Archives of Singapore (NAS) is a collection of some 10,000 maps that originate primarily from three government agencies – the Survey Division of the Singapore Land Authority (SLA), whose beginnings trace back to the Straits Settlements Survey Department formed in the mid-19th century; the Singapore Armed Forces Mapping Unit (SAFMU) formed in 1970; and the Maritime Port Authority (MPA) established in 1996 and its predecessor the Port of Singapore Authority (PSA; formed in 1964). The collection also contains copies of maps of Singapore acquired from overseas archives, notably the National Archives of the United Kingdom (NAUK) and the British Library, as well as maps from various private collectors.
The maps in the NAS collection fall into the following broad categories:
General Reference Maps
These maps show a variety of different physical features at a given location, such as coastlines, water bodies, vegetation, hills and mountains, roads, commercial, industrial, residential and recreational areas. These maps comprise two types: small-scale, covering large geographical areas such as whole countries or regions, or large-scale, covering a small geographical area but providing more detail on local physical features.1 The general reference maps in the NAS collection include maps of Asia and Southeast Asia, maps of Singapore town and island, various street maps and district or precinct maps. There are presently around 3,800 general reference maps in the NAS collection.
Topographic maps are a type of small-scale general reference map that includes accurately measured contour and relief details providing users with a reliable three-dimensional sense of the space being mapped. Such maps typically provide highly detailed information of the local environment and are generally the most comprehensive type of small-scale general reference map available. Singapore’s first complete set of topographic maps was published in 1924 by the Survey Department of the Federated Malay States and Straits Settlements and, subsequently, many general reference maps of Singapore have included topographic details. There are presently around 1,300 topographic maps in the NAS collection.
Cadastral maps are drawn up by state land-use authorities to document and demarcate parcels of physical property claimed by different property owners. These maps are used to establish property boundaries and legal claim over property as well as to estimate land values and assess property tax.2 As cadastral maps were traditionally used by the government to aid the tax collection process. they were sometimes referred to as “revenue maps”. There are currently about 3,300 cadastral maps in the NAS collection.
These are sea navigation charts used by mariners to sail through open or near-shore waters. Such charts display features such as soundings (the depth of water at a given location), shoal waters, lights, key landmarks such as lighthouses and buoys, harbour approaches and anchorages, a compass rose to orientate the map and other information to aid navigation. Such maps are termed “charts” as they are not only meant to be looked at, but are also used as working material to be marked up by navigators in the course of their work. There are presently about 700 hydrographic charts in the NAS collection.
These are special purpose maps typically overlaid with details specific to the concerns of the user, for example, mining, urban and transportation planning, soil and environmental information, flood and disease control, and military planning. NAS has a small collection of fewer than a hundred of such maps. However, many more thematic maps can be found embedded within archived government reports, files and publications where they are frequently used as supporting and illustrative documents.
The vast majority of maps in the NAS collection (numbering over 8,000) are geographic maps of Singapore. These include maps of the island of Singapore and its surrounding waters, and of particular areas and districts of the island, notably the heavily populated town centre as well as outlying precincts like Katong, Jurong and Changi. In addition, the collection contains about 900 maps of Malaya dating to pre-1963. These maps illustrate the Malayan Peninsula, the seas around it and specific places such as the capital Kuala Lumpur and major towns such as Penang, Malacca and Johor. A small number of maps of Southeast Asia and wider Asia are also part of this collection.
Maps Spanning 190 Years: From 1819 to 2009
Fewer than 40 maps from the NAS collection are from the pre-1819 period before Singapore was founded. Most of these early maps date from the late 18th century to the early 1800s and are mainly of British as well as Dutch and Portuguese origins.
NAS holds about 190 maps from the early colonial period (1819–1866) when Singapore was administered together with Penang and Malacca as part of the Straits Settlements under the British East India Company and subsequently the British India government based in Calcutta. This period marked the beginning of more precise mapping of Singapore’s physical environment. 3
NAS has about 530 maps spanning the next 50 years of Singapore’s history, starting from 1867 when the Straits Settlements was elevated to a British Crown Colony administered directly by the Colonial Office in London to the end of World War I in 1918. Relatively few maps of Singapore were produced during this period due to limited funding and lack of skilled manpower.4
The years 1919 to 1938, between the end of World War I and the outbreak of World War II, was an important period for cartography in Singapore as concerted efforts were made to improve the quality of local maps. NAS has a rich collection of about 1,700 maps covering this period. In 1920, a decision was made to initiate a modern trigonometrical survey of the Straits Settlements that would later enhance the accuracy of subsequent maps. One of the results of this effort was a comprehensive 16-part coloured topographic map of Singapore published in 1924. This was the first proper topographical map of Singapore ever made and represented a considerable improvement in accuracy over previous mapping. 5
NAS has about 700 maps from the World War II period (1939–1945), covering the tense years following the outbreak of war in Europe, the battles for Malaya and Singapore, and the Japanese Occupation. Highlights of the collection include British topographical maps of Malaya and Singapore from 1939 that were drafted as part of war preparations. Also of interest are reproduction copies of British and Japanese military maps capturing troop movements during the course of the Malayan and Singapore campaigns, as well as British military planning maps drawn up as part of the Allied effort to recapture Malaya and Singapore. Most of these British military maps were obtained from NAUK and the British Library, while the Japanese maps were either reproduced or acquired from private collections.
NAS has a collection of over 2,200 maps covering the period from the restoration of British rule at the end of World War II to Singapore’s emergence as a sovereign republic. A notable development in the cartography of this period is the introduction of aerial photography, which led to the production of Singapore’s first aerial maps in the 1940s. Aerial photography replaced traditional trigonometric surveys of the post-war period as it was a much faster and cost effective way of producing accurate topographic maps.6 These aerial photographs are available for viewing in the NAS image database, together with a selection of stitched aerial photomaps of the central parts of Singapore from the NAS map collection.
Political changes saw Singapore transform progressively from a British colony into a self-governing and then independent state, leading to the general election to select representatives to Singapore’s legislature in 1948 and the drafting of the first electoral maps. The first urban masterplan maps, which provided comprehensive information of land usage patterns across Singapore, were also published during this period in 1958.7
Finally, the NAS collection contains about 4,200 maps published between August 1965 and 2009 – the period when Singapore became a sovereign independent Republic to the date of the latest maps deposited with the NAS. Important developments that took place during this time include the establishment of the SAFMU in 1970, which is part of the Ministry of Defence. SAFMU took over responsibility for the nation’s topographic mapping, allowing the Survey Department to concentrate on creating cadastral and other survey maps. Notably, in 1971, SAFMU published the first topographic map created under the Republic of Singapore.8
From the 1980s onwards, computerisation and digitisation of mapping emerged as new digital technologies gradually displaced analogue mapping techniques.9 The NAS collection also contains a number of modern hydrographic maps created by the MPA and its predecessor the PSA, the most recent of which was published in 2009.

The National Archives of Singapore (NAS) is the official custodian of all records of national and historical significance that serve as the corporate and social memory of the Singapore government and its people. NAS holds possibly the largest collection of Singapore maps, numbering around 10,000. These are available to the public and include an extensive collection of survey and topographic maps dating from the British colonial era to modern times.

The first map which accurately traced the outline of Singapore island emerged around 1822, sketched by Captain James Franklin, a visiting Bengal military surveyor. Detailed maps of the rapidly developing Singapore town as well as hydrographic charts of its surrounding waters also emerged.
