Digital Surface Model (DSM) of 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. These data products are a lasting resource for land managers, local government, and the scientific community as we grapple with the challenges of building community resilience and conserving key coastal resources and environments in a time of rapid change.
