GeoSystems Engineering


Geosystems Sensing and Analytics Laboratory (GeoSAL)

The Geosystems Sensing and Analytics Laboratory (GeoSAL) is housed at the Hearst Mining Building, about 1 min walk from Davis Hall. GeoSAL enables modern techniques for field characterization, in-situ testing, field sensing and monitoring of infrastructure and the geoenvironment.

GeoSAL promotes multi-scale, integrated, innovative sensing at the component (local) and system (regional) level. Key to leveraging the sensing capabilities is the ability to analyze big data collected by our sensors, robots and satellites using customized scripts and Artificial Intelligence algorithms.
