Abstract

Data is regularly gridded at 18 seconds of latitude and longitude (approximately 500 metres). The source data for this grid is the spot elevation data held in the TOPO-250K Series 1 Relief theme.

Lineage

The DEM has been derived from Geoscience Australia's GEODATA TOPO-250K Relief theme which consists of more than 5 million spot elevations taken from contours or observed during 1:100 000 scale map production. (These points have an RMS of less than 10 metres.)
