Collection Overview: LiDAR was captured for Environment Canterbury Regional Council by Aerial Surveys Ltd from 1 May 2020 to 22 April 2024. In the summer months of 2025, small, isolated areas were re-flown to address data voids. The dataset was generated by Aerial Surveys and their subcontractors. Data management and distribution is by Toitū Te Whenua Land Information New Zealand.
Prepared DEM files are available through the LINZ Data Service:
