From Images to Prevention. Gigapixel Imaging for Geohazards Assessment and Awareness

The growing frequency of geohazards such as landslides, rockfalls, and slope instabilities, often intensified by climate change and human activities, underscores the urgent need for effective assessment and monitoring tools. Traditional remote sensing techniques like LiDAR, aerial photogrammetry, and satellite interferometry (InSAR) rely on substantial financial and technical resources, which limit their accessibility. In response, Gigapixel imaging emerges as an innovative and cost-effective alternative, offering ultra-high-resolution visual data to support geohazard assessment while raising awareness among stakeholders and the public.
The CDRI’s fellowship GIGA2 is aimed at exploring the practical implications of integrating Gigapixel imaging into geohazard monitoring and modelling. Beyond its technical advantages, it promotes inclusivity in geoscience by providing an accessible and impactful tool for communicating risks and fostering preparedness. By bridging the gap between advanced technology and practical application, Gigapixel imaging offers a promising pathway for enhancing geohazard assessment and resilience in vulnerable areas.
