Scientific Investigations Report 5095

NOTE: This model and accompanying files have been approved for release 
and publication by the Director of the USGS.  Although this database has 
been subjected to rigorous review and is substantially complete, the 
USGS reserves the right to revise the data pursuant to further analysis 
and review.  Furthermore, it is released on condition that neither the 
USGS nor the United States Government may be held liable for any damages 
resulting from its authorized or unauthorized use.

The database can be downloaded from the USGS server on URL 
http://pubs.usgs.gov/sir/2007/5095/.  

Demo viewers are provided for Linux and Windows platforms.  

Software may be run directly from the Internet but best performance is
achieved by copying files to the local system.

To run the program, run the executable file "evviewer.exe".  Upon starting 
of the program a menu will appear allowing for file selection.  The Menu 
must be navigated to the folders containing the appropriate files.  To move 
to a folder higher up in the hierarchy double-click the path ending with 
"/.." in the left column.  Double-click the desired folder in the left column 
to enter that directory.  When readable files are available they will appear 
in the right column.  To select the desired file click once to the left of 
the file name at which point an asterisks will appear adjacent to the file 
name identifying it as selected.  Then click "no more selections" at the 
bottom of the menu.

System configuration requirements and many other common 3D viewer operations 
are described in QuickHelp.pdf.  More advanced capabilities are described in 
the file 3Dviewer.pdf.
