Overlapping seabed images collected at Big Pine Ledge coral reef, Florida, 2022

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2023-11-08T00:00:00Z
A total of 118,965 underwater images were collected at Big Pine Ledge, Florida, in July 2022, using the novel SfM (Structure-from-Motion) Quantitative Underwater Imaging Device with 5 cameras (SQUID-5) system. The SQUID-5 is a towed surface vehicle with five downward-looking underwater cameras developed by the U.S. Geological Survey (USGS), and records images in the Tagged Image File Format (.tif) to maintain the highest resolution and bit depth. Each image includes imagery header metadata (including, but not limited to: Global navigation satellite system (GNSS) date, time, latitude, longitude, and altitude of the GNSS antenna mounted on the vehicle, copyright, and keywords).
