Delaware Coastal Inundation 2017 2.0

LiDAR based 1-m DEM was used to develop new bathtub-model coastal inundation maps for the state of Delaware. Inundation maps include surfaces from Mean Higher-High Water (MHHW) to 7 feet above MHHW, in 1-foot increments. These maps will help assess the potential impacts of sea-level rise, storm surges, and numerous other applications and will advise long-range planning of infrastructure, facilities, land management, land use, and capital spending.基于激光雷达（LiDAR）的1米分辨率数字高程模型（Digital Elevation Model，DEM）被用于为特拉华州开发新型浴缸型沿海淹没地图。该批淹没地图覆盖的高程区间为平均高高潮位（Mean Higher-High Water，MHHW）至平均高高潮位以上7英尺，以1英尺为间隔递增。此类地图可用于评估海平面上升、风暴潮的潜在影响，适配多项其他应用场景，同时可为基础设施、公共设施、土地管理、土地利用及资本支出的长期规划提供决策参考。
