CFM Web Development

SCEC's CXM group is developing a distribution method for SCEC's CFM v5.2 fault model data set. The goal of this effort is to develop a Community Fault Model Discovery and Distribution System that helps the SCEC research community make use of the CFM.

Information about the spreadsheet file

• Need Identification of meaning of selected columns

Contents of CFM spreadsheet file

We are deciding how to correct various identified issues with speadsheet data including:

• The shape file has duplicate entries from a same fault dataset.
• The spreadsheet contents to review include:
• "SALT-CPFZ-CRPR-Cierro_Prieto_fault-CFM1-trace" was included into the shapefiles two times,
• xlsx has duplicate abbreviation for different regions,
  • San Cayetano fault zone,SCFZ
  • San Clemente fault zone,SCFZ
  • South Cuyama-Ozena fault zone,SCFZ
• Possible typos,
  • Cross Faults,CRSF
  • Cross faults,CRSF
  • Western Big Pine,WEST
  • Western splay - north,WEST
  • Western splay,WEST
  • Western,WEST
  • Brawley Seismic Zone,BSZ
  • Brawley Seismic Zone,BSZS

Geometry File Converter Information

• Testing shows that Tsurf is mesh data but no vanilla mesh viewer takes it straight. More common format is OBJ.
• The CFM group has many converters and one of them is Tsurf to OBJ. Several 3d mesh viewer code that takes OBJ.
• Evaluate a prototype using x3dom.js.

Earlier CFM Viewer Developments

During early CFM workshops to get community feedback, the group were working with the UCSD group to visualize the CFM in 3D with Fledermaus. Fledermaus has a free 3D viewer - which used to be iView3D but is now iView4D, with Win-32, Win-64, MacOSX, & Linux versions of iView4D available, and like other approaches, the data need to be reformatted for this app.

• 3D Viewer

This software was adopted by the USGS for 3D visualization:

• USGS 3D Viz Example

Workshops on its use as of 2012:

• USGS 3D Viz Workshop

In terms of the CFM webpage, we are discussing if there is still a need to provide additional 3D visualization resources for the CFM and other CXM products. If so, a iView4D plus MoVE Viewer may be a useful combination.
