DEMs are a mass of ground heights representing a terrain surface. In this instance they are spaced at a regular grid interval. This dataset has been developed from aerial photography as part of the Land Monitor salinity study program. The status of coverage is available either directly or via remote access to Land Monitor's website http://www.landmonitor.wa.gov.au/ Information relative to a specific map DEM data may be obtained directly through the DOLA contact.

A Digital Elevation Model (DEM / DTM) in a 100 metre grid covering the whitsunday area, this includes the Proserpine, O`Connell, Pioneer and Plane catchments. A DEM refers to a model of elevation values. They may be used to derive other terrain attributes. DEMs are sometimes referred to as digital terrain models (DTM), a general term applied to models of elevation, slope, aspect or other terrain attributes. DEMs are built from datasets of varying type, scale and accuracy. They may be made from ground surveyed or photogrammetrically obtained heights, existing topographic maps usually originally obtained from analogue photogrammetry, or using radar or laser altimetry data from aircraft or satellites.

The original source of this DEM is unknown. Metadata and licence conditions have also not been supplied. The Bet Bet DEM has a cell resolution of 5m. The DEM was generated from 10 m interval contours, ground surface points, watercourses and lakes coverages using Topogrid tool in Arcinfo 8 ESRI software.

This DEM data has been generated from a wide range of aerial photography) by Landgate WA (formerly WA Dept. of Land Information). As a result, there are various associated photoscales and acquisition dates. The DEM has been supplied to the ATWS for the purpose of modelling and have been mosaiced into pre-determined areas by Landgate based on the ATWS research. DEM's and contours are available in a number of formats. Metadata and Licence conditions supplied. Internal requests for the data should be addressed to the ATWS. Other requests should be addressed to DLI Western Australia.

Victorian 25m DEM acquired by GA as part of the National DEM Project. Licence conditions not supplied.
