USGS Data Series 1095: Nearshore Single-Beam Bathymetry Data Collected in 2015, Dauphin Island, Alabama

The datasets described in this report can be downloaded from the accompanying USGS data release (DeWitt and others, 2017) or by using the table below. The x,y,z point datasets are provided in comma-delimited ASCII format in three datums: (1) ITRF2000, (2) NAD83 (CORS96) and NAVD88 (orthometric height), and (3) NAD83 (CORS96) and MLLW. Formal Federal Geographic Data Committee (FGDC) metadata files are associated with each dataset as an individual downloadable file or located within the dataset zip file. GIS data files (DEM and trackline shapefiles) can be opened with Esri ArcGIS or freeware products such as ArcGIS Explorer, Google Earth, and QGIS GIS viewers. Field Activity Collection System (FACS) documents, generated from a combination of scanned handwritten and digital field notes and logs, are provided in PDF format and can be viewed using the free software Adobe Reader.
