This dataset provides a Digital Elevation Model (DEM) for LiDAR data captured in the Auckland region in 2013.
Point Cloud Data
You can access the point cloud data and generate custom elevation models through OpenTopography
Access via OpenTopography is provided as a trial of online point cloud distribution and on-the-fly product generation.
Alternatively, you can request the LAS or LAZ point cloud by contacting LINZ at:
We want your feedback
These datasets are being made available as a trial to evaluate the value of making LiDAR based elevation data openly available via the LINZ Data Service. During this trial phase, you may be contacted by LINZ so we can better understand your use of the data.
Data collection and attributes
LiDAR was captured for Auckland Council by NZ Aerial Mapping & Aerial Surveying Limited. The capture of the data commenced on 17th July and was completed by the 23 November 2013. The datasets were generated by both ASL and NZAM. All raw point cloud data was produced by NZAM & ASL prior to data being sent to Genesys International for the data classification and product generation. The survey area includes the Auckland city urban area and adjacent rural land covering approximately 2250 square kilometers. Data management and distribution external to Auckland Council is managed by Land Information New Zealand.
