How to Include Crowd-Sourced Photogrammetry in a Geohazard Observatory—Case Study of the Giant’s Causeway Coastal Cliffs

Crowd-sourced Structure-from-Motion photogrammetry can effectively integrate citizen-collected data into geohazard monitoring programs, as demonstrated by a study at the Giant’s Causeway and Causeway Coast UNESCO World Heritage Site. The research found that the Time-SIFT method yields high-quality reconstructions with an 8.6 cm standard deviation, making it suitable for long-term landslide observation in areas like Port Ganny. This approach leverages high tourist footfall to enhance spatial and temporal data coverage while raising public awareness of coastal cliff risks. Unlike traditional methods, it requires no specialized expertise from participants, offering a scalable solution for citizen science in geohazard management.
