A geotechnical GIS has been configured by the California Department of Conservation's Division of Mines and Geology for the purpose of designating seismic hazard zones as mandated by recent legislation. In addition to conventional GIS capabilities, the system has special geotechnical features including stereo photogeologic analysis, subsurface geological mapping, remote sensing, and sofcopy photogrammetry. Because these capabilities can be costly, the configuration of a geotechnical GIS should be driven by a careful analysis of functional requirements.
