Structure-from-Motion bathymetric maps from the Florida Keys, 2019

Summary

Structure-from-Motion (SfM) bathymetric maps were created using seafloor images collected using the new 5-camera system SfM Quantitative Underwater Imaging Device with Five Cameras (SQUID-5). Images were collected during July 2019 by towing the SQUID-5 in 3 to 4 meters of water off of Islamorada in the Florida Keys during 3 days. 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. Bathymetric maps were created from the photos using SfM photogrammetric software.

Purpose

These bathymetric maps were produced to assess the accuracy, precision, and effectiveness of the new SQUID-5 camera platform.
