LiDAR data

LiDAR (Light Detection and Ranging) uses light in the form of a pulsed laser (typically from an aircraft) to measure 'ranges', thereby enabling the accurate calculation of distances and elevations in a 3D environment.

About our LiDAR dataset

As the State’s custodian of elevation data, we’re making our existing LiDAR data archive (and future acquisitions) available for use by State & local governments and the commercial sector. Our repository comprises of acquisitions since 2017, captured over specific areas of the state in support of various state-based initiatives and at various resolutions.

There are two types of LiDAR – topographic and bathymetric (seabed). The Landgate offerings are topographic only and are available as either Raw or Classified. In some instances, derived DEMs or contours are also available.


  • raw – unprocessed point cloud
  • classified* – processed to differentiate between ground and non-ground features only
  • derived DEM* – 1m postings
  • contours* - 0.5m interval.

*where available

Landgate’s raw LiDAR data can be used in:

  • Land management (rehabilitation, benchmarking, erosion) 
  • Hazard management (landslides, earthquakes, floods, fires) 
  • Examining both natural and manmade environments 
  • Forestry (deforestation) and agriculture management 
  • Mining 
  • Creating digital twins 
  • Asset management (eg infrastructure corridor) 
  • Creating hi-res DEMs 


An indicative extent is shown below.
