#### Description

The Digital Elevation Model (DEM) 5 meter Grid of Australia
derived from LiDAR model represents a National 5 meter (bare
earth) DEM which has been derived from some 236 individual LiDAR
surveys between 2001 and 2015 covering an area in excess of 245,000
square kilometers. These surveys cover Australia's populated
coastal zone; floodplain surveys within the Murray Darling Basin,
and individual surveys of major and minor population centers.
All available 1 meter resolution LiDAR-derived DEMs have been
compiled and resampled using a neighborhood-mean method to 5
meter resolution datasets for each survey area, and then merged
into a single dataset for each State. Each state's dataset is
provided as a separate image within the image collection.

The acquisition of the individual LiDAR surveys and derivation
of the 5m product has been part of a long-term collaboration
between Geoscience Australia, the Cooperative Research Centre
for Spatial Information (CRCSI), the Departments of Climate Change
and Environment, State and Territory jurisdictions, Local Government
and the Murray Darling Basin Authority under the auspices of
the National Elevation Data Framework and Coastal and Urban DEM
Program. The source datasets have been captured to standards
that are generally consistent with the Australian ICSM LiDAR
Acquisition Specifications with require a fundamental vertical
accuracy of at least 0.30m (95% confidence) and horizontal accuracy
of at least 0.80m (95% confidence).

There are several areas close to Perth with null (NaN) values around
(115.85, -31.99), (115.72, -33.75), and (115.10, -33.43).
