This sub-project evaluated the performance of different technologies for the generation of digital elevation models, specifically in coastal environments. The accuracy characteristics of six such technologies were assessed within four test areas, on the mid north coast of New South Wales, chosen as being representative of low-lying coastal zones of differing land cover, topography and geomorphology.
An objective of the project was to look beyond differences in vertical resolution, cost and productivity, and to consider the overall performance of different DEMs in the context of fulfilling anticipated requirements for fit-for-purpose elevation data in Australia’s vulnerable coastal zones. Outcomes can be used to inform the development of future guidelines covering optimal DEM generation technologies for vulnerable coastal zones.
