New USGS Data Release — Crater geometry data for Puʻuʻōʻō, on Kīlauea Volcano’s East Rift Zone, in May 2018

The USGS recently published a data release that includes a three-dimensional model of Puʻuʻōʻō, on Kīlauea's East Rift Zone, and the collapse crater, constructed from aerial thermal images collected on 11 May 2018.  Structure-from-motion processing was used to create the model from the sequence of oblique images, and ground control using kinematic GPS was used to georegister the model.
