UAV Photogrammetry: A New Tool for Coastal Surveying and Management
Coastal erosion is a serious threat to the shorelines in the Northeast. Since erosion affects every property differently, a comprehensive approach that considers the specific characteristics of each coastal system is required. The first step before undertaking an erosion control project is an accurate compilation of historical data and an existing conditions survey.
As technology advances, so do the land survey methods. Modern photogrammetry uses unmanned aerial vehicles (UAVs, or drones) equipped with digital cameras to capture detailed aerial images. Photogrammetry allows for efficient data collection in hard-to-access or hazardous areas, ensuring complete coverage of the shoreline. It enables timely decision-making and proactive management strategies by providing real-time data and as such, it can be a valuable tool to complement the traditional surveying methods.
