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

<p>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&nbsp;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 <em>Coryphopterus personatus</em> and <em>Coryphopterus hyalinus</em> are included. All data were collected from Turneffe Atoll (17.3638&deg; N, 87.8581&deg; 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 <em>C. personatus</em>/<em>hyalinus. </em>All code associated with the analysis can be found here: <a href="https://github.com/jdselwyn/Habitat_Usage">https://github.com/jdselwyn/Habitat_Usage</a>.</p>
