Welcome to XNATMAP

A site for preserving NATMAP's (The Division of National Mapping) history and maintaining contact with the people who were part of that history. As the Australian Landsat Station (ALS), later the Australian Centre for Remote Sensing (ACRES) was part of the Division its history also forms part of this site.

Information on map reading and interpretation, specifically for Natmap medium scale topographic maps, can be found in
Natmap’s Topographic Maps : a guide to map reading and Notes on Map Reading by Reg Ford and Bob Goldsworthy.

    Australia’s Contribution to the PAGEOS Project

    By the mid-1960s the geodetic datums of Europe and South America had been connected to North America. Likewise, North Africa had been connected to Europe via Greece. However, while Australia and Papua New Guinea had had the islands to the north and east connected to them, this chain of stations remained isolated from the northern hemisphere.

    With the launch on 24 June 1966 of PAGEOS (Passive Geodetic Earth Orbiting Satellite), a global geodetic network was established to observe this satellite and establish a uniform geodetic datum. Commencing in 1967, Australia’s contribution to the success of this project was not insignificant and can be viewed via this link.

    What's New

      As of 1 November 2017

      • Guy Rosenberg joined National Mapping in 1960 and spent that year in the Tellurometer field party of OJ Bobroff. This party measured a continuous series of lines of the Geodetic Survey from the Carrieton base line in South Australia north to Powell Creek in the Northern Territory. When HA Bill Johnson asked Guy to transfer to Port Moresby, Papua New Guinea, to support David Cook, then Natmap's PNG Resident Surveyor for the Geodetic Survey, Guy accepted. Guy then spent until 1964 in PNG on the geodetic survey. On Christmas Day 1963 Guy along with Ed Burke and Ron Scott enjoyed a white Christmas on the summit (approximately 15000ft) of Mt Wilhelm. This rare event made the front page of PNG's newspaper of the time the South Pacific Post. Guy, who is now living back in his native France, has generously provided photographs of his time in PNG which may be viewed via this link.
      • Deal Island is the largest of the Kent Group of islands in Bass Straight. In the early summer of 1952 and later in early 1953, Deal Island was occupied by National Mapping's Reg Ford and an assistant to undertake the Bass Strait Triangulation which linked the geodetic surveys on the mainland with those on Tasmania. On both occasions, the Deal Island party was transported by the mailman on his regular run from Port Albert, Victoria. After being landed at the jetty at East Cove, the climb to the Deal Island Lighthouse took some 5 to 6 hours, the summit being almost 1,000 feet above sea level. While the Deal Island Lighthouse made a fine observing target it could not be used as an observing platform. The station mark for observing on the peak was thus some 680 feet from the lighthouse which was on a slightly lower peak. It was then necessary to measure down through a steep gully and up the other side to the centre of the lighthouse, and also read the required angles so that the calculation of the correction for the eccentric light could be made. During this survey, the line Deal Island back to Mount Fatigue, Victoria, was the longest observed at almost 84 miles (130 kilometres approximately). Now living outside of Yarram, Victoria, ex-Natmapper Laurie Edebohls became interested in this bit of history and arranged a flight over Deal Island in July 2017. This short (about 3 minutes) video (no audio) was acquired by him during the flight.
      • Natmap lost one of its characters and a gentlemen, with the recent passing of Ian Jeffrey Miller (26 May 1946 - 9 October 2017). A Vale has now been prepared and is available via this link.
      • Frank Johnston's outstanding career as a professional surveyor extended over more than 40 years and involved undertaking major engineering and mapping projects as well as teaching new geospatial professionals. Frank's surveying and mapping work with National Mapping commenced in 1958 and ended in 1974. However, it was only between 1971 and 1974 that Frank was employed as a Nat Map staff member, in that period he was an Aerodist field party leader. In this article Laurie McLean provides a biographical sketch of Frank Johnston and also gives brief glimpses of some of the major professional figures with whom Frank interacted.
      • The little known Relief Model of Australia is a 64 square metre representation of Australia at approximately 1: 500,000 scale. Conceived, and built under his supervision by Edwin Sherbon Hills (1906-1986) of the University of Melbourne, it was initially financed by the Army but finally completed with funding from National Mapping in 1954. The Commonwealth's copy of the 26 parts of the model is housed by Museums Victoria in its Moreland Storage Annex in Melbourne.
      • An album of photographs, taken during his days of field work with Natmap, courtesy Laurie Edebohls may be viewed this link.
      • William James Sear (1900-1986) was National Mapping's chief cartographer from 16 March 1950 until his retirement at age 65 years on 2 July 1965. In this article Laurie McLean provides an outline of Bill Sear's life and his career as a draftsman that spanned some 48 years.
      • The technology of Electronic Distance Measuring (EDM) was a major factor in the successful completion of Australia's national survey and mapping programs. Terrestrial and later airborne EDM systems evolved from World War Two radar developments and were at the forefront of surveying technology until the advent of satellite-based surveying and navigation technology in the 1970s. This paper Airborne Electronic Distance Measuring : A Brief History seeks to catalogue the major airborne distance measuring systems that were developed during the twentieth century, with the focus on the history and use of airborne EDM used in, or associated with, the surveying and mapping of Australia.
      • The Aerodist airborne distance measuring system was used by Nat Map between 1963 and 1974 to obtain horizontal ground control for the 1:100,000 scale national topographic map series. Laurie McLean has prepared this extensive article on Nat Map's Aerodist years in consultation with many of the Nat Mappers who were involved in the Aerodist program from up to over half a century ago. The article incorporates many of these Nat Mappers' recollections.

      • Training Notes for National Mapping Field Survey Staff were compiled by Reginald Arthur Ford, Senior Technical Officer, while he was the Training Officer for the Melbourne Office. After many years of field experience, Reg documented most of the Nat Map Melbourne's accepted field survey procedures and methodologies covered by these notes. As such this document represents the consistent standard provided to and expected from all involved in field survey work during the late 1960s and 1970s. These notes were never published but just photocopied as required. This web version was derived from the personal copies provided by a number of Natmappers and their cooperation is appreciated. While every effort has been made to ensure correct conversion, users may find minor inconsistencies in the text and tables.
      • Collected articles and papers about the USAF Southwest Pacific Survey, Project AF60-13 and its use of HIRAN.
        A 25 minute (75MB download, MP4 file) 1961 USAF film on geodesy by Hiran can be viewed via this link. The film also has some interesting glimpses of various supporting technologies.
