The Urban Digital Elevation Model Project is an initiative of the Commonwealth Department of Climate Change as part of a program of coastal vulnerability assessment.
The high resolution Digital Elevation Model builds on the Federal Government's current mid-resolution digital elevation model investment which identifies areas of likely exposure to climate change risks. Airborne laser scanning, also known as LiDAR (Light Detection And Ranging) and high resolution digital airborne imagery, together with advanced analysis techniques, will help identify which infrastructure and areas of high population density are most at risk. This assessment of risk will be an ongoing process of improvement
as other key sources of data are obtained, such as bathymetry(a digital elevation model of these floor),the coastal geomorphology (the structure of the coastline and its erodibility), local wave climatology and |

storm modeling.
This site has been released to a restricted audience to demonstrate the various uses of elevation data in flood and
inundation modelling. The modelled inundation levels take into account hydrogeological flows and ground elevation heights. Other factors such as geomorphological effects of sea level rise over time, the bathymetry, wave action and storm intensity are not taken into account with this site. The inundation model as viewed should be considered as very approximate only and is only intended for the restricted audience. The following disclaimer applies. |
