Vicmap Elevation 1m DEM

Overview

The Vicmap Elevation 1m Digital Elevation Model (DEM) is a mosaic product that delivers the best available 1m DEM data for Victoria through spatial web services.

The spatial web services include terrain, relief, hill shade and footprints.

The data used in the 1m DEM draws from the state's archive of ground surface model datasets known as the Vicmap LiDAR DEMs Collection.

Only datasets meeting 1m resolution and +/- 10cm RMSE vertical accuracy standards are included in the Vicmap 1m DEM.

Data access

The Vicmap 1m DEM web services are currently only available under license to Government users. Private companies and members of the public can contact our Data Service Providers to access the data used in the 1m DEM web services.

You can view free 3D samples of the Vicmap 1m DEM data using our Sample Service viewer. The map also shows the set of footprints for all DEM datasets used across the Vicmap 1M DEM web services. The footprints can help identify specific DEM datasets when requesting data from our Data Service Providers.

Subscribers will also receive a fully documented Vicmap 1m DEM User Guide that describes the services in detail including service URL’s and connection instructions.
The Vicmap 1m DEM also includes a Vicmap 1m DEM – Footprints web service as well as Vicmap 1m DEM Sample Service Viewer that are openly available for anyone to use (no subscription required).
The Footprints service provides details of the DEM datasets used in the Vicmap 1m DEM.
The Sample Service viewer provides snippets of the Vicmap 1m DEM – Shaded Relief service to demonstrate the detail available.
The Samples User Guide has instructions for connecting the Vicmap 1m DEM Footprints and the Vicmap 1m DEM Sample Services directly into your own applications.

The licensed Vicmap 1m DEM web services can be loaded directly into applications by using subscriber credentials. This includes the Digital Twin Victoria (DTV) platform.
Subscribers will receive a fully documented Vicmap 1m DEM User Guide that describes the services in detail including service URL’s and connection instructions.
The open Vicmap 1m DEM Footprints and Sample Service viewer can be loaded into applications without any subscriber credentials.

Data coverage is governed by purchase partner investment in aerial LiDAR surveys undertaken through the state’s Coordinated Imagery Program (CIP). The LiDAR surveys generate the DEM datasets that are used in the Vicmap 1m DEM and to date, significant portions of the State remain unsurveyed by LiDAR.
The expansion of the Vicmap 1m DEM coverage is critically tied to future purchase partner investment in LiDAR surveys over previously unsurveyed parts of the state. Importantly, whenever repeat LiDAR coverage is achieved, the latest data for any given area will always be included. The Vicmap 1m DEM Footprints are key to understanding the datasets that make up the 1m DEM coverage.

The Vicmap 1m DEM footprints are key to understanding the datasets that make up the 1m DEM coverage. The footprint attributes include the date of the source LiDAR surveys from which the contributing DEM datasets were derived.
The Vicmap 1m DEM Footprints can be accessed through a map viewer showing the footprints as well as the set of Vicmap 1m DEM Sample Services.
The Sample Services User Guide has instructions for connecting the Vicmap 1m DEM Footprints and Sample Services directly into your own applications.

Membership to the Vicmap Elevation Subscription Plan includes access to the Vicmap 1m DEM web services, the Vicmap LiDAR Points collection and the Vicmap LiDAR DEMs collection from which the Vicmap 1m DEM is sourced. Visit the Vicmap Elevation web page for more information on these collections.
Alternatively, non-subscribers can still purchase a License to access the source data used in the Vicmap 1m DEM from the state’s Value Added Resellers (VARs) and Data Service Providers (DSPs).

The Vicmap 1m DEM will be updated whenever new, qualifying data becomes available through the Coordinated Imagery Program. The timing of updates will depend on purchase partner investment in new LiDAR surveys which can be random and sporadic in nature.

New LiDAR surveys that contribute DEM data to the Vicmap 1m DEM can be arranged by contacting the Coordinated Imagery Program (CIP) via email at coordinated.imagery@transport.vic.gov.au.
