Dave is being modest here. I believe he also introduced LTPlus to the US
Bureau of Land Management (BLM) and a number of other organizations. In
addition, Dave, along with Tuyen Ngo, performed the first major porting of
the program (from Xenix to SCO Unix/ODT). As I think about it, he was also
the one who introduced me to LTPlus. To be certain, neither LT4X, Delta3D,
or LTPlus-for-Linux would exist now if it weren't for this man. 

On the downside, he was the one who introduced John Dabritz (the prime
author of LTPlus) and Holly Martin to Infotec... (is John still speaking 
with you Dave?)

I am. At present I am working on a version that utilizes Tcl as a macro
language, supports HTML based help pages, and allows vector digitizing
(along a number of other goodies). Anyone interested in the current 
status of the project is welcome to visit
