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 elevations of offshore bathymetric transects perpendicular to State of Hawaii Department of Transportation (HDOT) routes in the Hawaiian Islands. Individual maps show transects of coastal areas adjacent to 302 mileposts along State of Hawaii Department of Transportation (HDOT) 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 Hawaiian bathymetric digital elevation model (DEM) created by the Hawaii Mapping Research Group (HMRG, 2016).

本数据库包含一系列地图和图表，展示了夏威夷群岛州交通部（HDOT）路线垂直方向上的离岸地形剖面高度。单张地图展示了与夏威夷、茂宜、莫洛凯、欧胡和考艾岛州交通部（HDOT）州际公路相邻的海岸区域剖面。这些剖面区域是根据全州海岸公路项目报告，已被识别出易受气候变化影响的地区。里程碑由Brandes等人（2019年）进行标识。州际公路和县街道中心线数据集来源于HDOT（2017年）和HOLIS、C&CH（2017年）。剖面高度以局部平均海平面（LMSL）为基准，并从夏威夷地形数字高程模型（DEM）中采样，该模型由夏威夷制图研究组（HMRG，2016年）创建。请参阅‘Description-Map of Offshore Bathymetric Transects along Peak Wave Directions.docx’以获取详细信息。
