Drone Mapping Dataset – Seasonal Structure & Metadata Template – RTK-GNSS & SfM – Sugarloaf Island, NC

This template provides a complete folder structure, metadata standards, and processing documentation for curating drone-based shoreline monitoring datasets with RTK-GNSS and Structure-from-Motion (SfM) photogrammetry. Originally developed for multi-season coastal monitoring at Sugarloaf Island, North Carolina (2023–2025), it is designed for reuse by researchers and collaborators working in similar coastal environments.The template includes:A detailed Standard Operating Procedure (SOP) in PDF formatReusable metadata templates for point clouds, DEMs, orthomosaics, GNSS control, and nature-based shoreline feature shapefilesAn example seasonal dataset folder with structured subfolders for paired East and West segmentsRefer to README_Drone_Data_Curation_Template.txt for setup and usage instructions.This item also includes a supplementary script folder (code_montecarlo_metashape_1.6.zip) containing a Monte Carlo bundle adjustment script for Agisoft Metashape 1.6+, adapted from James et al. (2017). The script and accompanying README support reproducibility of the RTK-GNSS and SfM georeferencing validation workflow.
