Spot Height Data for Australia, Australian Survey and Land Information Group (AUSLIG)

The AUSLIG Spot Height Data are derived from the Australian National
Spot Height Database. The data are enhanced for incorporation into
Geographic Information Systems.

The following text was abstracted from Bruce Gittings' Digital
Elevation Data Catalogue: 'http://www.geo.ed.ac.uk/home/ded.html'.
The catalogue is a comprehensive source of information on digital
elevation data and should be retrieved in its entirety for additional
information.

Australian Data is available from the Australian Survey and Land
Information Group (AUSLIG). There are three products; M7 are Critical
Aeronautical Heights which represent the highest point in each 30'x30'
quad, M8 are Spot heights (ie. an irregular grid) and M9 represents an
18" (~500m) grid at 1:250,000 scale (gridded from M8 using an
Hutchinson Algorithm). Both M8 and M9 have incomplete coverage of the
country.

The 500m grid covers 30% of Australia (Southern New South Wales,
Victoria, parts of Northern Queensland and selected cities). The size
of the 1:250 000 scale files is 60,501 points each x 63 files =
38,176,131 elevation points. Costs: License 1:250 000 AU$1000 / File
1:100 000 AU$250.

NB. 1996: 100m and 200m DEMs covering all of Australia are also
now available. Prices are as follows (in US Dollars):
