This flowchart (PNG image, 26KB) shows the step-by-step process I used to produce my results. This version may be easier to read, depending on your browser and monitor settings.

Summary

Here are the primary tools I used:

• Adobe Acrobat to extract text from Dr. Reynolds' paper (PDF format, 15MB).
• awk, a Unix program, to help reformat some of the data files.
• C shells to help process some of the data files.
• GMT, a collection of programs to process map-related data and produce maps.
• IRIS Explorer, a program that can view Virtual Reality scenes.
• MapSource, a program to manage data collected by my Garmin Emap GPS.
• Microsoft Excel to open the spreadsheet (Excel format, 208KB) Dr. Reynolds sent me, and export the data in a usable format.
• Perl, a free programming language, to help reformat some of the data files.
• VRML, a language that helps make "Virtual Reality" scenes.

Shell Scripts and Programs

• c.hw08-3
• c.hw08-4
• c.surface
• makebbox.pl
• makeiv.pl
• makeroad.pl
• makesurf.pl
• makewell.pl
• scale.pl
• subsurf.pl
• wells.sh - This is the "master" shell script that drives everything else.

Intermediate Data Files

The following files were produced at one step in the process to be read back in later.

• 0.0bed.draw
• 0.0bed.surf
• 20021117.txt
• 20021117.lin
• bed.color
• bed.xyz
• fill.xyz
• phx_basin_subsurface_final_39-53.fix
• phx_basin_subsurface_final_39-53.ssf
• phx_basin_subsurface_final_39-53.txt
• phx_basin_subsurface_final_39-53.vi
• roads.lin
• top.xyz
• wells.txt
• wells02.txt
• wells07.psxyz
• wells07.txt
• wells08.box
• wells08.txt

VRML Images

Note: These are VRML 1.0 Virtual Reality images. Because of significant changes in the VRML language, these images will not be visible in web browsers that have a VRML 2.0 viewer installed.

These images were then combined to produce my final results.

• roads.iv - road map from GPS
• roadsx3.iv - 3X vertical exaggeration road map
• surfbed.iv - bedrock topographic surface
• surfbedx3.iv - 3X vertical exaggeration bedrock
• wells.iv - drill holes (wells) with colors indicating rock types encountered at each depth
• wellsx3.iv - 3X vertical exaggeration wells
