Spatial Distribution and Habitat Usage of <i>Coryphopterus personatus</i> and <i>C. hyalinus</i> in Turneffe Atoll, Belize

Data used to develop 3D models of coral reefs using structure-from-motion photogrammetry. The data used to generate photogrammetry models are pictures of the reef from ~1 m above the substratum and coordinates of ground control points for each of twelve distinct ~20 m x 10 m reef areas. The photogrammetry workflow to create the digital models included photo alignment, followed by geometry building, and lastly texture building using Agisoft Pro. Additionally included are the orthomosaics and digital elevation models derived from the 3D models and training data used to build a classification algorithm to classify reef vs sand benthic types using the site orthomosaics. Finally, the location and sizes of mixed shoals of Coryphopterus personatus and Coryphopterus hyalinus are included. All data were collected from Turneffe Atoll (17.3638° N, 87.8581° W), Belize in January 2017. These data are used in conjunction to develop a habitat usage model to understand what features of coral reefs are correlated with the distribution of C. personatus/hyalinus.
