The Three-Dimensional
Geologic Maps and Visualization Project is developing techniques to
construct three-dimensional geologic maps that retain all the information
of traditional geologic maps while providing a more detailed picture of
the subsurface.
Computer-based representations extend beyond the capability of a standard
Geographic Information System to provide continuous quantitative information
for land-use planning, hazard mitigation, and resource management. Such
representations allow the non-geologist user to 'walk around' in the Earth
to examine data and extract information.
The project
is using geologic map data from the San Francisco Bay area to compile 3-D
geologic maps of a broad region centered on Silicon Valley. These maps will
be used as a framework for ground-shaking estimation, refined earthquake
and fault location, resource exploration, contaminant-source and dispersion-pathway
definition, ground-water flow modeling, and landslide modeling.
