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.

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.

Airborne Electronic Distance Measuring : A Brief History
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 revised paper is an attempt 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.

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.
