Description:

Abstract:

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.

Purpose:

These photos were collected to determine the accuracy, precision, and effectiveness of the new SQUID-5 camera platform.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

The horizontal and vertical accuracies of the surface models were compared against GPS survey data of known features covered by the survey.

Logical_Consistency_Report: All data fall within expected ranges.
Completeness_Report:

Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

SfM-based measurements of the Sediment Elevation Table (SET) stations were within 3 cm of the total uncertainty of the field-based GPS measurements. The average horizontal scaling of the models is between 0.016 and 0.024 percent of water depth.

Process_Description:

Data Collection: Photographs were collected in bitmap (bmp) format in synchronized quintets by the SQUID-5 system, towed behind the R/V Sallenger during USGS field activity 2019-630-FA (aka 2019-323-FA). Image collection frequency was 2 Hz, and a post-processed kinematic (PPK) GPS position was recorded for each collection instant. Image gain settings were adjusted as needed depending on water depth and lighting conditions. Aperture and shutter speed were consistent for each group of photos at a study site. Image files were named programmatically with the last two digits of the camera's serial number, a 14-digit UTC datetime value formatted as yyyymmddhhmmss, thousandths of seconds, and the sequential image number for that camera. For example, 'CAM30-20190713152206_462-209.bmp' means camera 30, July 13, 2019, 15:22:06.462 (UTC), file number 209. Images were matched with GPS position data based on the timestamp of the image, and the position data were imported into the exif header or each png image file.
