Collection Overview: The July 2018 LiDAR data collection over the Kilauea Summit and the Lower East Rift Zone was conducted by the US Army Cold Regions Research & Engineering Lab (CRREL), The University of Houston and the USGS. Funding was provided by the State of Hawaii and the Federal Emergency Management Agency (FEMA). The system utilized was an R44 helicopter based pod which uses a Riegl VQ580i full waveform laser scanner. Total of 9 flights over the course of 5 days (July 8 - 12, 2018). This survey covers portions of Hawaii Volcano National Park on the Big Island of Hawaii as Kilauea volcano continues to erupt in Summer, 2018. The survey area covers approximately 122.4 km2. Note that in order to provide quick access to the data, the initial geo-registered flight lines were the product of near-real-time trajectory and calibration processing in the field.  Dataset obtained from the USGS  Kilauea LiDAR  website. Please refer to that site for additional information. Version Note: An initial version of this dataset, available from OpenTopography between July 23rd and 27th, 2018, had low classified ground point density due to a processing error. An updated version of the dataset (v.2), reprocessed by the US Army CRREL, was published by OpenTopography on July 30th, 2018 at 19:00 MDT.

Dataset Acknowledgement: Any use of this data should acknowledge lidar data acquisition completed by NCALM, processing by CRREL, and funding provided by USGS.
