This dataset is used to display the images and locations of bottom photographs acquired with a GoPro modified, mid-sized SEABed OBservation and Sampling System (SEABOSS Mark II configuration) collected during a 2014 USGS cruise along the Delmarva Peninsula. The information contained within the bottom photographs is needed to validate geophysical data. This dataset contains an image from each bottom photograph station, as well as location in easting and northing (UTM, Zone 18N, WGS84, meters), time of day and date of collection. Physical sediment samples, which also may provide information about the seabed, were also collected at photograph stations and analyzed in the sediment laboratory at the USGS Woods Hole Coastal and Marine Science Center (see shapefile 2014_002_samples.shp)
The following tags were populated in the JPEG image headers. Information is duplicated in some tags. This was done because different software packages access different tags.
GPS tags: The values populated are unique for each image and based on the information exported from the photo locations shapefile.
GPSLatitudeRef GPSLatitude GPSLongitudeRef GPSLongitude GPSTimeStamp GSPDateStampJPEG tags: The tag is listed along with the information used to populate it - which is the same for every image taken with a particular camera. The following information is based on the GoPro Hero 2 camera.

Caption: Photograph of the sea floor along the Delmarva Peninsula, MD and VA from survey 2014-002-FATo extract the information from the image headers using ExifTool, the following command can be used (tested with ExifTool version 9.4.6.0):
exiftool.exe -csv -f -filename -GPSTimeStamp -GPSLongitude -GPSLatitude -n -Artist -Credit -comment -keywords -Caption -Copyright -CopyrightNotice -Caption-Abstract -ImageDescription hero2/*.jpg > out.csv
The -csv flag writes the information out in a comma-delimited format. The -n option formats the latitude and longitude as signed decimal degrees.
The following tags are modified for the hero3 files.
