Orthoimagery of Looe Key, Florida, 2022
A seabed orthoimage was developed from underwater images collected at Looe Key (LKR), Florida, in July 2022 using the SfM (Structure-from-Motion) Quantitative Underwater Imaging Device with 5 cameras (SQUID-5) system. The underwater images were processed using SfM photogrammetry techniques. The orthoimage covers a rectangular area of seafloor approximately 850x160 meters (m) (0.13 square kilometers [km]) in size. It was created using image-averaging methods and saved as Geographic Tagged Image File Format (GeoTIFF) rasters at 5-millimeter (mm) resolution, in a 5-by-2 tile index grid. A 25-centimeter (cm) resolution "quicklook" version of this orthoimage is also included in this data release so that users can quickly view the entire dataset at a lower resolution before downloading the higher resolution raster tiles.
