Bathymetry and acoustic backscatter data from Floras Lake, Oregon, June 2018

This publication releases single-beam bathymetry and backscatter datasets acquired by the U.S. Geological Survey (USGS) during surveys performed on Floras Lake, Oregon, in June 2018. Bathymetry and backscatter data were collected using two personal watercraft (PWCs) equipped with single-beam sonar systems, sidescan sonar systems, and global navigation satellite system (GNSS) receivers. Bathymetry data are provided as point data in a comma-separated text file and are projected in cartesian coordinates using the Universal Transverse Mercator (UTM), Zone 10 North, meters coordinate system, with elevations relative to the NAVD88 vertical datum. Acoustic-backscatter data are provided as a GeoTIFF file also projected in UTM Zone 10 North, meters coordinate system.

本数据集为美国地质调查局（U.S. Geological Survey, USGS）于2018年6月在俄勒冈州弗洛拉斯湖开展勘测期间获取的单波束测深与反向散射数据集。本次勘测采用两台搭载单波束声呐系统、侧扫声呐系统及全球导航卫星系统（global navigation satellite system, GNSS）接收机的个人水上交通工具（personal watercraft, PWCs）采集测深与反向散射数据。测深数据以逗号分隔文本文件的点数据形式提供，采用通用横轴墨卡托（Universal Transverse Mercator, UTM）北10带米制坐标系进行笛卡尔坐标投影，高程基准为NAVD88垂直基准面。声学反向散射数据以GeoTIFF文件形式提供，同样采用UTM北10带米制坐标系进行投影。
