Beach Topography—Fire Island, New York, Post-Hurricane Sandy, April 2014: Ground Based Lidar (ASCII XYZ Point Data)

The U.S. Geological Survey St. Petersburg Coastal and Marine Science Center (USGS-SPCMSC) and the U.S. Army Corps of Engineers Field Research Facility (USACE-FRF) of Duck, NC collaborated to gather alongshore ground-based lidar beach topography at Fire Island, NY. This high-resolution elevation dataset was collected on April 1, 2014, and is part of the USGS's ongoing beach monitoring effort under Hurricane Sandy Supplemental Project GS2-2B. This USGS Data Release includes the resulting processed elevation point data (xyz) and an interpolated digital elevation model (DEM).

美国地质调查局圣彼得斯堡海岸与海洋科学中心（U.S. Geological Survey St. Petersburg Coastal and Marine Science Center，简称USGS-SPCMSC）与位于北卡罗来纳州达克市的美国陆军工程兵团野外研究设施（U.S. Army Corps of Engineers Field Research Facility，简称USACE-FRF）合作，在纽约州火岛采集了沿岸地面激光雷达（lidar）海滩地形数据。该高分辨率高程数据集采集于2014年4月1日，隶属于美国地质调查局在“桑迪飓风补充项目GS2-2B”框架下持续推进的海滩监测工作。本次美国地质调查局数据发布包含处理后的高程点数据（xyz格式）以及插值生成的数字高程模型（Digital Elevation Model, DEM）。
