Adam R. Mosbrucker
Geomatics expert with the USGS Cascades Volcano Observatory
Geomatics integrates geospatial science and technology disciplines such as photogrammetry, remote sensing, GIS, GNSS, and geodesy. These are fundamental tools for Volcano Science Center monitoring and research projects.
I specialize in quantitative fluvial geomorphology, which uses geomatics, field instrumentation, and sampling to study sediment transport in disturbed volcanic systems. My current research focus is developing innovative uses of camera systems, including high-precision photogrammetric models of vegetated river channels and a suspended-sediment surrogate based on close-range multispectral ‘SedCam’ imagery.
As the Volcano Hazards Program Lidar Coordinator, I leverage local and national partnerships to acquire topographic data needed for volcano hazard modeling, mapping, and eruption forecasting efforts.

A survey base station is established using a RTK-GPS receiver with mobile units to collect data points in and around the crater. Information will be used to monitor surface changes, deformation, erosion and aggradation inside the crater. This type of technology is precise to the centimeter. View is to the south of Mount St.
