Well I finally found some time today to put together an article on In Cave Digital Survey(ICDS). It details the equipment used and the ICDS Process. It also contains links to Adobe Illustrator files for download for users of Illustrator 9,10, or CS.
You can view the article online at: http://incavedigitalsurvey.com/board/YaBB.pl?num=1205624025 or http://tinyurl.com/yqbmro For those interested in ICDS I recommend reading and viewing: The Walls Manual especially the section on Roundtripping SVG Maps http://www.cavediggers.com/walls32.pdf and Brandon Kowallis's Adobe Illustrator Tutorials at http://incavedigitalsurvey.com/board/YaBB.pl?num=1192498613 or http://tinyurl.com/2zpzks Mark Passerby, InCaveDigitalSurvey.com
