A Slice of PI-CASC Seminar: Big Island, big coastline

Hawai‘i Island, the largest and most diverse island in the Hawaiian archipelago, lacks a comprehensive detailed shoreline inventory. Dr. Ryan Perroy will discuss an ongoing project, in partnership with PI-CASC and the Hawai‘i County Planning Department, to generate this inventory for 428 km of coastline via the collection and processing of high-resolution imagery using a custom helicopter-mounted imaging system. The collected imagery and derived three-dimensional products are being used to identify areas most at-risk from sea-level rise impacts and should be a lasting resource as we grapple with the challenges of resilience and coastal resource conservation in a time of rising sea levels.
