World class geodesy

19 June 2003


Geodesy is the study of the Earth's shape, the measurement of the position and motion of points on the Earth's surface, and the distribution and area of large portions of the earth's surface.

Geoscience Australia's Space Geodesy Analysis Group has received accreditation for its accurate GPS positioning capabilities from the National Association of Testing Authorities Australia (NATA), Australia's Government-endorsed provider of accreditation for laboratories and similar testing facilities.

Geodesy supports many professional, economic and scientific activities and functions, ranging from land titling to mineral exploration; from navigation, mapping and surveying to the use of remote sensing data for resource management; from the construction of dams and drains, to the interpretation of seismic disturbances.

With the increasing use of GPS in surveying, for example in positioning of property boundaries in cadastral surveying, there is a clear need for standards in positioning.

The NATA report stated that "The facility is staffed by very professional and experienced staff who run a world-class geodesy service."

NATA also noted that the QA system was of a high standard and very well integrated.
