Abstract
Abstract: 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 . The status of coverage is available either directly or via remote access to Land Monitors website http://www.landmonitor.wa.gov.au/ Information relative to specific DEM data may be obtained directly through the Landgate contact. 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.

Lineage
Lineage: DEM data was derived by digital photogrammetry sourced from aerial photography. The aerial photography was scanned prior to automatic aerotriangulation with the DEM generation and editing being carried out by contractors. 10% of the DEM was checked by Landgate.
