Topobathymetric Model of Pu'uhonua O Honaunau National Historical Park, 2011 to 2019 - Field Survey Source and Validation Data

U.S. Geological Survey (USGS) and University of Hawaii - Manoa (UH) scientists conducted field data collection efforts from August 19th - 27th, 2019 at Pu'uhonua O Honaunau National Historical Park on the Big Island of Hawaii. The data collection efforts utilized a combination of remote sensing technologies to map the topography, critical infrastructure, and most importantly, the cultural assets of Pu'uhonua O Honaunau National Historical Park. The USGS and UH team collected Global Navigation Satellite System (GNSS), total station, and ground based lidar (GBL) data, along with utilizing Uncrewed Aerial Systems (UAS) to collect imagery and UAS lidar to map these features. This data release contains shapefiles of the processed GNSS and total station data, point clouds in the form of lidar data exchange (LAS) files from the ground and UAS lidar data and aerial imagery produced via Structure from Motion (SfM). See the List of Files under the Native Data Set Environment section for file names and sizes. The processed data contained in this release served as source and validation data for a spatially integrated topobathymetric digital elevation model (TBDEM) for Pu'uhonua O Honaunau National Historical Park.
