Purpose

Vicmap Elevation provides an accurate representation of natural relief features across Victoria. It is used in a variety of applications, particularly in emergency services, natural resource management, planning and development, and digital map publication. 

Format

Native Format: ESRI Grid 2 

Supplemental Information

History: In 2016, the 10m DEM was improved and updated using recent high-resolution LiDAR surveys. Related Documents: None Please see Vicmap product description for more detailed information. This can be found on the Vicmap webpage. https://www.land.vic.gov.au/maps-and-spatial/spatial-data/vicmap-catalogue/vicmap-elevation

Quality

Conceptual Consistency

The DEM values across initial basin tiles have been constructed to ensure smooth consistent elevation values are achieved. 

Missing Data

Vicmap Elevation DEM 10m covers the State of Victoria. 

Attribute Quality

The vertical accuracy associated with the DEMs is +/-5m or better. The overall vertical accuracy of the product is calculated to be 2.96m. Beware that reprojecting, changing format or resampling causes changes to the height values in the DEM. 

Positional Accuracy

The spatial accuracy for Vicmap Elevation DEM 10m is inherited from the spatial accuracies of its many source datasets. The most consistently used underlying product to create the Vicmap DEM and therefore the base for positional accuracy is the Vicmap Elevation 10-20 Contours & Relief, therefore the positional accuracy for Vicmap Elevation DEM 10m is 12.5m horizontally and 5m vertically or better. This accuracy has been checked through a formal quality assurance process. 

Lineage

Description

The methodology utilizes a combination of ArcInfo TIN and ANUDEM processes to ensure that stream enforcement is achieved while maintaining a DTM which closely conforms to the original input data. More information on the methodology can be found in the product.
