  • Structure-from-Motion underwater photos from the Florida Keys, 2019

    Metadata Updated: November 12, 2020

    Underwater photos were collected using a new 5-camera system, the Structure-from-Motion (SfM) Quantitative Underwater Imaging Device with Five Cameras (SQUID-5). Images were collected in July 2019 by towing the SQUID-5 in 3 to 4 meters of water off of Islamorada in the Florida Keys. The five cameras were synchronized together and with a survey-grade Global Positioning System (GPS). Images were collected over diverse benthic settings, including living and senile reefs, rubble, and sand. The images are presented here in zipped files grouped by Julian day. The SQUID-5 system records images in bitmap (.bmp) format to maintain the highest resolution and bit depth, and these were the files used in SfM processing. The zip files also contain portable network graphics (.png) files, an open-source format, and which include Exif metadata, including GPS date, time, and latitude and longitude, copyright, keywords, and other fields.
