Dataset description: Overlapping seabed images collected at Looe Key, Florida, 2021

A total of 94,567 underwater images were collected at Looe Key, Florida, in July 2021, using the SQUID5 Structure-from-Motion (SfM) system, a towed-surface vehicle with five downward-looking underwater cameras developed by the U.S. Geological Survey. The images are organized in zipped files grouped by survey line. The SQUID-5 records images in the Tagged Image File Format format to maintain the highest resolution and bit depth. Each image includes Exchangeable Image File (EXIF) metadata, containing Global navigation satellite system (GNSS) date, time, latitude, longitude, and altitude of the GNSS antenna mounted on the towed surface vehicle, copyright, keywords, and other fields.
