Data Stewardship Maturity Report for Cold Bay, Alaska 8/15 arc-second Coastal Digital Elevation Model

NOAA's National Geophysical Data Center (NGDC) is building high-resolution digital elevation models (DEMs) to support individual coastal States as part of the National Tsunami Hazard Mitigation Program's (NTHMP) efforts to improve community preparedness and hazard mitigation. These integrated bathymetric-topographic DEMs are used to support tsunami and coastal inundation mapping.

美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration，NOAA）下属的国家地球物理数据中心（National Geophysical Data Center，NGDC）正构建高分辨率数字高程模型（digital elevation models，DEMs），作为国家海啸减灾计划（National Tsunami Hazard Mitigation Program，NTHMP）提升社区防灾准备能力与灾害减灾水平工作举措的一部分，为各沿海州提供支持。此类集成测深与地形数据的数字高程模型可用于支撑海啸与海岸淹没范围制图工作。
