This project involved creating detailed and highly accurate digital terrain model of a large underground mining site to prepare for its Expansion plans.

With the site covering approximately 10,000 hectares of vegetated and rugged terrain, Airborne LiDAR was utilised to map the above ground surface of the mine. Complex flight planning was necessary to map a site of this scale and photogrammetry was also undertaken to produce an Orthophoto of the site. Orion also undertook accurate control survey to assist with reduction of the LiDAR data and Photogrammetry. Orion provided infill Detail Survey around mining infrastructure not suitable for survey by LiDAR and processed both datasets to create and overall Digital Terrain Model for the site.

Utilising Airborne LiDAR enabled Orion to map the site in approximately 3 weeks, which would have taken 6 months using traditional survey methods.
