Case History Michigan Basin
Case History Imaging Fracture Zone, Italy TomoSeis Acquired Data, GeoTomo Processed Data
Case History Image Buried Concrete This is a geophysical engineering application. A concrete object was buried under a paved road. Crosshole imaging between two holes with 30-feet separation was performed to locate the object. Golder Associates performed field work and tomographic imaging with TomoXPro
