What is the real 3-D geologic map?
The block diagrams of the Santa Clara Valley 3D geologic map shown in the About the map and What information goes into the map? sections are not the actual geologic map, but are simply graphical representations extracted from the digital database that contains the complete map information. The real 3D geologic map, although not yet complete, exists within the computer as a complex, highly organized set of digital files and instructions. The 3D geologic map is framed around the earthVision® geologic modeling and visualization software and retains the fundamental architecture of traditional geologic maps while extending it into the third dimension. Lines on the 2D geologic map (e.g. faults, intrusive contacts, depositional contacts, etc.,) become surfaces, and areas transform into volumes in 3 dimensions. The current 3D geologic map of the Santa Clara Valley is being constructed following a rigorous sequence of procedures. First, point data representing discrete 3D locations on a given g
