U.S. Coastal Relief Model Vol.7 - Central Pacific

NGDC's U.S. Coastal Relief Model (CRM) provides the first comprehensive view of the U.S. coastal zone integrating offshore bathymetry with land topography into a seamless representation of the coast. The CRM spans the U.S. East and West Coasts, the northern coast of the Gulf of Mexico, Puerto Rico, and Hawaii, reaching out to, and in places even beyond, the continental slope. Bathymetric and topographic data sources include: NGDC's NOS hydrographic surveys, multibeam bathymetry, and trackline bathymetry; the U.S. Geological Survey (USGS); and other federal government agencies and academic institutions. Bathymetric contours from the International Bathymetric Chart of the Caribbean Sea and the Gulf of Mexico project were also used. Digital elevation models (DEMs) of the Great Lakes, Southern Alaska, and high-resolution DEMs of U.S. coastal communities and territories are also available.

美国国家地理数据中心（National Geophysical Data Center, NGDC）的美国海岸地形起伏模型（Coastal Relief Model, CRM）首次实现了美国海岸带的全面可视化呈现，将近海水深数据与陆地地形数据整合为一套无缝衔接的海岸整体表征。该模型覆盖范围涵盖美国东、西海岸，墨西哥湾北部沿岸，波多黎各及夏威夷群岛，延伸至大陆坡区域，部分点位甚至超出大陆坡范围。其水深与地形数据来源包括：NGDC下属的国家海洋服务局（National Ocean Service, NOS）水文测量数据、多波束水深测量数据以及测线水深测量数据；美国地质调查局（United States Geological Survey, USGS）；其他联邦政府机构及学术研究机构。此外，项目还采用了加勒比海与墨西哥湾国际水深图项目产出的水深等值线数据。同时，该数据集还提供了五大湖、阿拉斯加南部的数字高程模型（Digital Elevation Model, DEM），以及美国沿海社区与领地的高分辨率数字高程模型。
