Coastal Interferometric Swath Bathymetry Data Collected in 2015 from the Chandeleur Islands, Louisiana: 2015_Chand_IFB_5m_NAD83_NAVD88_GEOID09_XYZ

The U.S. Geological Survey St. Petersburg Coastal and Marine Science Center (USGS SPCMSC), collected swath bathymetry data offshore of the Northern Chandeleur Islands, Louisiana in September 2015. This USGS Data Release includes the resulting processed elevation point data (xyz) and an interpolated digital elevation model (DEM). For further information regarding data collection and/or processing methods, refer to previously published USGS Data Series 847 and 848 (http://dx.doi.org/10.3133/ds8487 and http://dx.doi.org10.3133/ds848)美国地质调查局圣彼得堡海岸与海洋科学中心（U.S. Geological Survey St. Petersburg Coastal and Marine Science Center，缩写USGS SPCMSC）于2015年9月采集了路易斯安那州北尚德莱尔岛近海的条带测深数据（swath bathymetry data）。本次美国地质调查局数据发布包含经处理得到的高程点数据（xyz格式）以及插值生成的数字高程模型（Digital Elevation Model，DEM）。如需了解数据采集与处理方法的详细信息，请参阅已发表的美国地质调查局数据系列第847号与第848号（访问链接：http://dx.doi.org/10.3133/ds8487 及 http://dx.doi.org/10.3133/ds848）。
