The 2017 New Zealand Geotechnical Society paper by D. J. Bevan, Martin Brook, Jon Tunnicliffe, Nick Richards and W. M. Prebble provides a clear professional example. The team mapped the Kepa Road landslide in Auckland and the Ohuka landslide south of Port Waikato using a DJI Inspire 1 fitted with a Zenmuse X3 camera. Roughly 200 to 300 overlapping photographs were collected at each site. Up to 20 ground-control points, including targets and identifiable features, were positioned using real-time kinematic GPS.
