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.

Field Equipment

GeoSAL houses a diverse and unique set of Field testing and Monitoring equipment that is used in support of our Research and Education Mission

Virtual & Mixed Reality Hub

GeoSAL has in-house capabilities in support of Virtual Reality, Mixed Reality and Visualization projects. These capabilities are used in both research and teaching activities

Sensor Development

GeoSAL has equipment and staff that support manufacturing (mechanical and electronics), development and placement of sensors

Disasters Response Hub

GeoSAL support the Cal Geosystems team in immediate deployments to disaster affected areas. Our team has deployed to numerous locations globally and nationwide following earthquakes, huricanes, monsoons, floods and wildfires. Team members have a history of leadership with the GEER organization.

Big Data Analytics

GeoSAL has ongoing research projects that focus harness the large amounts of data generated by sensors, robots and autonomous infrastructure. Such approaches are commonly AI-based and include Digital Twins methodologies, machine learning frameworks, digital image analysis algorithms, data fusion frameworks.
