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.

        Alan Gordon Gutteridge (1892-1942)
        The engineering firm Gutteridge Haskins and Davey was one of several photogrammetric services contractors that provided compilation and other services to the Division of National Mapping for the 1:100 000 scale National Topographic Map Series. Outstanding,Tasmanian-born civil engineer Gordon Gutteridge was one of the founders of GH&D. In this article Laurie McLean gives a brief outline of the life of Gordon Gutteridge, his remarkable siblings and of a few other people associated with GH&D.

        WILD Heerbrugg Model T4 Universal Theodolite : their known Australian history
        Wild produced a total of 439 model T4 theodolites between 1941 and 1981, of which it appears that four were used operationally in Australia. All four T4's still exist and as little was documented, this article attempts to summarise the use of the T4 by the respective agencies.

        Stellar Observation Programs in National Mapping
        The stellar observation programs of Astronomical fixes (Astrofixes) for mapping control, the Ney Method for survey control used periodically in Antarctica and Laplace observations for azimuth control, spheroid determination and geoidal profiling are discussed in this paper.

        Australian Primary Data Acquisition Progress Maps for Topographic Mapping 1827-1988
        While there were various maps showing a south land from antiquity and the later navigator/explorers, these maps were mostly of coastline. Some forty years after the First Fleet arrived, in 1827 then Major (later Sir) Thomas Livingstone Mitchell (1792-1855) as Surveyor General saw the first systematic surveying and mapping of Australia. After that, settlement drove the need for mapping. As the XNATMAP website enters it fifteenth year an accumulation of information on Australian primary data acquisition for topographic mapping, gathered and standardised during those years, is presented by Paul Wise.
