The Royal Australian Survey Corps (RA Svy) was a Corps of the Australian Army, formed on 1 July 1915 and disbanded on 1 July 1996. As one of the principal military survey units in Australia, the role of the Royal Australian Survey Corps was to provide the maps, aeronautical charts, hydrographical charts and geodetic and control survey data required for land combat operations. Functional responsibilities associated with this role were: theatre wide geodetic survey for – artillery, naval gunfire and close air support – mapping and charting – navigation systems – command and control, communications, intelligence, reconnaissance and surveillance systems; map production and printing for new maps and charts, plans, overprints, battle maps, air photo mosaics and photomaps, rapid map and chart revision; map holding and map distribution; production, maintenance and distribution of digital topographic information and products. RA Svy survey and mapping information was, and still is, a key information source for geospatial intelligence. The operational doctrine was that the combat force deployed into the area of operations with topographic products adequate for planning, force insertion and initial conduct of tactical operations, that new products and broad area updates of the topographic base would be provided by the support area and communication zone survey forces, and that the combat support survey force in the area of operations would update the topographic base, add tactical operational and intelligence information and provide the value-added products required by the combat force. The Historical Collection of the Survey Corps is maintained by the Australian Army Museum of Military Engineering at Holsworthy Barracks, south-west Sydney, New South Wales. Survey Corps Associations of ex-members, family and friends are located in Adelaide, Bendigo, Brisbane, Canberra, Perth and Sydney. Many wartime maps produced by the Survey Corps are in the Australian War Memorial collection, while all of the maps produced by the Corps are also in the national collection at the National Library of Australia. All of these are available to the public and some are on-line. History Origins Australia's first surveyor, Lieutenant Augustus Alt, was an Army officer of the 8th (The King's) Regiment of Foot, which arrived in Australia with the First Fleet in January 1788. Eighteen years before him, Lieutenant James Cook, Royal Navy, used his knowledge and skills of topographic survey by plane-table for his surveys and charting of the east coast. This graphical method of topographic survey, first used before 1600, was
