Vicmap Elevation - 10-20 Contours & Relief
This product represents Victoria’s elevations in the form of contours, spot heights and surface features including cliffs, embankments and rocky outcrops among others. The 10-20 metre contours and spot heights are the source datasets used to create Vicmap Elevation – DTM20m & DTM10m.

This product can be used in a variety of applications, particularly in emergency services, natural resource management, planning and development and digital map publication. These datasets can also be used in conjunction with other Vicmap Digital datasets, particularly 1:25,000 Vicmap Transport and Hydro.

Vicmap Elevation - 1-5 Contours & Relief
This product is an elevation dataset sourced from Melbourne Metropolitan Board of Works surveys conducted in the 1970s and 1980s. This valuable dataset enables a more detailed contour overlay of the Melbourne metropolitan area.

This spatial information can be used for feature and contour surveys, planning applications and broad scale volume estimations.

NOTE- Data is incomplete, ie. there are 'holes' in the data where there are quarries, roadworks or large building sites. Areas of this dataset was originally captured in 1 metre, 2 metre or 5 metre contour intervals. Two an five metre tiles are generally located in the outer, steeper localities. Customers need to satisfy themselves they are happy with changing contour intervals within Localities.

Vicmap Elevation – Coastal 1m DEM and 0.5m Contours
