2022-334-FA_BocaChica_Polecam_Imagery: High-resolution Geophysical and Imagery Data Collected in November 2022 Offshore of Boca Chica Key, FL
Description
Underwater images totaling 23,948 in number were collected offshore of Boca Chica Key, the Florida Keys , during November 2022, using the Polecam system developed by the U.S. Geological Survey (USGS). The Polecam system is a single downward-looking underwater Teledyne FLIR camera with a Computar V1228-MPY lens and with a rigidly-attached Global Navigation Satellite System (GNSS) antenna mounted directly above the camera's central axis. The pole camera was attached to the gunwale of the USGS research vessel (R/V) Sallenger. The Polecam system captured images as Tag Image File Format (TIFF, .tif) files to maintain the highest resolution and bit depth. In this data release, the files were converted into Joint Photographic Experts Group (JPEG, .jpg) file to enhance the accessibility of the imagery. Each image contains imagery header metadata embedded within the file, including GNSS date, time, latitude and longitude of the GNSS antenna, copyright, keywords, and other descriptive information. Refer to the ‘IMAGERY HEADERS’ Process Step of the metadata for more information on the imagery headers.
