Beach Topography— Terrestrial-Based Lidar Beach Topography of Fire Island, New York, June 2014

The U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) in Florida and the USGS Lower Mississippi-Gulf Water Science Center (LMG WSC) in Montgomery, Alabama, collaborated to gather alongshore terrestrial-based lidar beach elevation data at Fire Island, New York. This high-resolution elevation dataset was collected on June 11, 2014, to characterize beach topography and document ongoing beach evolution and recovery, and is part of the ongoing beach monitoring within the Hurricane Sandy Supplemental Project GS2-2B. This USGS data series includes the resulting processed elevation point data (xyz) and an interpolated digital elevation model (DEM).美国地质调查局（U.S. Geological Survey, USGS）佛罗里达圣彼得堡海岸与海洋科学中心（St. Petersburg Coastal and Marine Science Center, SPCMSC）与阿拉巴马州蒙哥马利的USGS下密西西比河-墨西哥湾水科学中心（Lower Mississippi-Gulf Water Science Center, LMG WSC）合作，在纽约州火岛采集了沿岸地面激光雷达（lidar）海滩高程数据。该高分辨率高程数据集采集于2014年6月11日，旨在表征海滩地形、记录海滩持续演化与恢复进程，属于"桑迪飓风补充项目GS2-2B"下持续海滩监测工作的组成部分。本USGS数据集系列包含最终处理完成的xyz格式高程点数据，以及插值生成的数字高程模型（Digital Elevation Model, DEM）。
