    • National Coral Reef Monitoring Program: Orthorectified mosaic images of Bird Key Coral Reef from Dry Tortugas collected on 2018-07-10 to 2018-07-11 (NCEI Accession 0208101)

    Metadata Updated: June 1, 2025

    This data set contains landscape mosaic images, created as a product for the NOAA Coral Reef Conservation Program’s (CRCP) National Coral Reef Monitoring Program (NCRMP). Orthorectified mosaic images of six reef plots were captured in Bird Key Coral Reef in Dry Tortugas National Park, United States. Each reef plot is made up of a 10m x 10m transect area (100 m2). Landscape mosaics are a composite of many underwater images stitched together. These mosaics have the clarity and pixel size of the individual pictures but collectively produce a “landscape view” of the coral reef community within each transect. A scuba diver holds the mosaic rig, containing two separate cameras, above the transect while swimming in a lawnmower pattern creating a crosshatching design. The diver takes these underwater images about one to two meters above the seabed at a rate of one image per second per camera. This swimming technique allows the mosaic rig to gather 1500-3000 images which are then merged into a single “landscape mosaic image” file via Agisoft Photoscan® software. A total of six TIFF (.tif) files are included in this dataset, one TIFF file corresponds to one reef transect plot area.
