Topo scanning services

Also, I am aware that LT-Plus (?) does this. Is this program public domain?
If so, where can I get a copy?

  I'm not too sure what LTPlus does exactly (have yet to make it work
  under SCO) but it is part of the GRASS 4.1 distribution.
  It's also available by itself on ftp.informatik.uni-kiel.de as
  /pub/packages/grass/LTPlus.tar.gz (.gz means you need GNU gzip
  to uncompress it)
