Hawaii Map and Plot Series of Offshore Bathymetric Transects along Peak Wave Directions for the Ocean Hazards Database

This database consists of a series of maps and plots showing transects of nearshore topographic and bathymetric elevations of Hawaii shorelines. Individual maps show transects of shorelines adjacent to 302 mileposts along Hawaii state routes on the islands of Hawaii, Maui, Molokai, Oahu and Kauai previously identified for their vulnerability to the effects of climate change as part of the Statewide Coastal Highways Project Report. Mileposts are identified by Brandes et al. (2019). HDOT state routes and county street centerline datasets are acquired from HDOT (2017) and HOLIS, C&CH (2017). Elevations along the transect are referenced to local mean sea level (LMSL) and are sampled from a merged digital elevation model (DEM) of Oahu prepared by Francis et al. (2019). Details on map datasets and their usage can be found in the 2019 State of Hawaii Statewide Coastal Highways Project Report.
