Q: What is the format of the digitized line?
A: .dig files is defining digitized lines (originally from NaviModel but also supported in Helmsman)
A simple point based format as follows:
#unit=m
-70167.81201 144089.31460 9.16067
-70146.32520 144064.38245 2.17448
-70137.81117 144052.75959 -0.57531
One line per point EAST NORTH HEIGHT
There are a few global flags included:
#unit=m
#Type=Pipe
#UserDefinedFlagName=<name> (only if Type=UserDefined)
#DrapeFlags=TRUE|FALSE (only for "flag" types)
