Title: Grid Digital Elevation Model (DEM), 3 Seconds of Arc


Custodian

Custodian: Geoscience Australia

Jurisdiction: Australia


Description

Abstract:

Contains a digital elevation model of parts of Australia. The DEM has a grid spacing of 3 seconds in latitude and longitude (approx 80 metres). Each value in the DEM represents the highest elevation for that part of the grid.

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 10metres.)

Positional accuracy:

These points have an RMS of less than 10metres.

Attribute accuracy:

Not Documented

Logical Consistency:

Not Documented

Completeness:
