Spatial Data Derived from High-Resolution Aerial Imagery Collected by Helicopter-Mounted Cameras Over the Shoreline of Hawai‘i Island in 2021-2022
The objective of this project was to create a shoreline inventory for Hawai‘i Island, the largest and most diverse island in the Hawaiian archipelago. This was done via the collection and processing of high-resolution (<4 cm) aerial imagery along the approximately 428 km long shoreline of Hawai‘i Island using a helicopter-mounted imaging system developed by the University of Hawai‘i at Hilo Spatial Data Analysis & Visualization (SDAV) research laboratory. The collected imagery is supplemented by survey-grade ground control data gathered across a limited number of high priority coastline segments, which were determined in coordination with the Hawai‘i County planning department and land managers. This data collection includes orthomosaics rasters, digital surface model rasters, bare earth digital elevation model rasters, classified point cloud las files, and model outputs of sea level rise inundation for the shoreline of Hawai'i. The files in each of these datasets are labeled with the quadrants of the island (Northeast, Northwest, Southeast and Southwest) and given priority levels based on the quality of shoreline remaining (high, medium, low). Bare earth digital elevation model rasters, classified point cloud las files, and model outputs of sea level rise inundation were only collected for High Priority segments.
