Kīlauea LiDAR

During the current eruption event at Kīlauea there have been numerous collections of Light Detection and Ranging (LiDAR) data in support of ongoing emergency operations. In addition, there are data sets collected in the past that are available here.

  • July 2018 - Aerial LiDAR scanning (Summit, Pu’u ‘Ō’ō, LERZ) by CRREL/NCALM /USGS
  • June 2018 - Aerial LiDAR scanning by USGS/QuantumSpatial/GEO1
  • 2012/2013 - Terrrestrial LiDAR of Kīlauea Summit by CRREL
  • 2009 - Aerial LiDAR of Kīlauea summit by NCALM

Processing

The initial georegistered flight line point clouds were delivered to the Cold Regions Research and Engineering Lab (CRREL - David Finnegan/Adam LeWinter) for follow on processing via PDAL using a CRREL Amazon cloud instance developed by Hobu Inc under contract to CRREL.

Details

All processing done with PDAL 1.7.2 and GDAL 2.2.0

  • Creation of 1km Tiles from flightlines. All flightlines were read to create a large virtual dataset and then filters.splitter was used to create 1km tiles.

  • Bare earth and noise processing. PDAL filters.outlier in default statistical mode was used to mark points as noise (Classification 7) and then non noise points were passed to filters.smrf (using defaults) and used to mark ground points using Classification 2.

  • Tiles were filtered on Classification 2 points and passed to the gdal writer using IDW (inverse distance weighting) to create DTMs with 1/2 m cell sizes

  • All DTM tiles were merged to 1 geotiff using GDAL 2.2 and written in compressed (LZW) and uncompressed format using Cloud Optimized GeoTIFF (COG) structure. A hillshade in compressed (LZW) and uncompressed was also made.

  • All DTM tiles were then processed using gdal_fillnodata.py to create filled DTMs. These were then merged in a similar fashion as in step 4.

  • Coordinate system was set to EPSG:6635+5703

July Aerial Data

The July 2018 LiDAR data Collection over the Kīlauea 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)

June 2018 Aerial Data

This data set was contracted by the USGS via Quantum Spatial, Inc., and acquired by GEO1 and Windward Aviation. GEO1 conducted the collection activity using a Windward Aviation Hughes 500 helicopter with a dual LiDAR scanning system that utilized two Riegl VUX-SYS scanners operated as one unit. The data set was acquired through 11 lifts, and comprises 4 distinct AOIs.

2012 – 2013 CRREL Terrestrial Scans

The 2012 - 2013 terrestrial LiDAR data collection over Kilauea’s Halema’uma’u Crater and Overlook lava lake was conducted by the US Army Cold Regions Research & Engineering Lab (CRREL), the University of Northern Colorado and the USGS Hawaiian Volcano Observatory (HVO). These data were collected using a Riegl VZ-1000 full-waveform laser scanner. The researchers tracked the growth of the Overlook lava lake crater over time and the lava lake surface activity using multi-temporal surveys.
