Vicmap Elevation DEM 10m

dataset: VICMAP_ELEV_DEM_10M
Vicmap Elevation DEM 10m is a product which is a raster representation of Victoria's elevation. DEM 10m has a spatial resolution of 10 metres with respective horizontal and vertical accuracy of 12.5m and 5m or better. The DEM is constructed from source data of various resolutions, accuracies and ages to produce an improved DEM containing increased detail in localised areas. The DEMs are hydrologically enforced and correctly defines the natural surface drainage and hydrological flow. This product has been quality assured by DELWP and additional third-party consultants. Update of the dataset Vicmap Elevation DTM 10m.

Quality

Attribute Quality
Comments
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
Comments
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. 
Conceptual Consistency
Comments
The DEM values across initial basin tiles have been constructed to ensure smooth consistent elevation values are achieved. 
Missing Data
Comments
Vicmap Elevation DEM 10m covers the State of Victoria.
