Subject: Questionnaire: Use of Digital Survey Tools in Cave Surveying
Hi All,
This is a questionnaire on use of digital survey tools in cave surveying:
https://mail.nmhu.edu/exchweb/bin/redir.asp?URL="">
Based on the efforts of many cavers over the past few decades, digital
survey tools have seen increasing use for underground surveying. A
number of cavers have been working in this area for some time. For
example, in the 1980s Frank Reid evaluated the use of a LIDAR device
for positioning caves and in 1986 John Ganter wrote on use of a
"Petro-Sonde" for finding passages in a Texas cave from the surface.
Through the 1990s, cave-mapping software became more and more
sophisticated: see work by David Mckenzie, Luc Le Blanc, Stacho
Mudrak, Martin Budaj, Gary Petrie, Larry Fish, and many more.
Radio-location techniques were practiced and perfected by Frank Reid,
Brian Pease, and others. Impressive 3D laser-mapping tools were used
by expeditions to generate multiple and realistic cross-sections of
Florida sinkholes. Many, including Mark Passerby, have worked
extensively on the process of using advanced/digital survey tools and
have recommended procedures for effectively doing so. Others, like
Phil Underwood (Shetland Attack Pony), have developed cave-specific
surveying tools. Recently, Aaron Addison and Lynn Brucker have
evaluated and used the Impulse and Attack Pony digital survey devices
and written about their experiences. There are many others who have
used high-tech tools for underground cave surveying. However, through
all this use of high-tech equipment, most surveyors have continued to
rely on the tried and true Suunto compass/clinometer and a fiberglass
survey tape.
Some feel that this may change someday, and we're wondering if it
isn't already happening. So, we're trying to determine how prevalent
the use of digital survey instruments is in current cave surveying. If
you could, please take a couple of minutes to fill out this short
questionnaire on digital survey tools. The results of this
questionnaire will be shared in a comprehensive presentation on
digital survey tools at the 2008 NSS Convention in Lake City, Florida,
USA in August 2008 and in a paper to be distributed after the NSS
convention. We hope you will take just a minute to fill out the
questionnaire and share your experience and feedback on cave
surveying.

Finally, we're not subscribed to all of the caving-related email
groups so please forward the URL as you are able.
thanks!
