This group of files contains coordinates for the surface traces of the San Andreas Fault as mapped at Parkfield, CA, by Michael Rymer (U.S. Geological Survey) and digitized by Christopher Crosby (Arizona State University).
The fault trace digitization was done as part of an NSF-funded project at Arizona State University: “Kilometer-scale fault zone structure and kinematics along the San Andreas Fault near Parkfield, California” supervised by Ramon Arrowsmith (NSF EAR-0310357).
Mapping is of approximately 21 km of the San Andreas Fault surface traces on the Smith Mountain, Stockdale Mountain, and Parkfield quadrangles.
Coordinates are in WGS84 reference frame (lat./long.) for each point. Fault traces are grouped into discrete files (separated by two blank lines) to denote discrete fault segments, with initial and final points of each file corresponding to segment end points and intermediate points corresponding to segment vertices.
