Survey path of the drone-based digital elevation model of White Island from December 2016. We focussed most of the photogrammetry survey towards the western subcrater, which is periodically infilled by a warm, acidic lake. At the time, there was no lake present and this survey attempted to quantify the topography of the inner crater basin ~ 8 months after the eruption described here. We used 16 ground control points that were co-located with survey pegs—labelled in red)
