CODEX developed a step-by-step photogrammetry workflow for collecting and processing drone-based imagery to produce morphological measurements of marine mammals with associated photogrammetric uncertainty. Our framework covers 1) Data collection (before takeoff and during flight), 2) Post-processing of imagery (image selection, measuring, linking metadata with measurements, and incorporating uncertainty), and 3) Morphometric analysis (including measurements with associated uncertainty into analysis). Our framework integrates several published open-source hardware and software tools, including automated tools, providing a centralized reference to help researchers enhance the quality, speed, and accuracy of obtaining important morphological measurements to help monitor marine mammal populations.
