I am not familiar with foxtrotgps but will look at it. I think it may
be overkill for my needs but maybe not. One thing is that I'm talking
about small distances -- spacing of <50 meters between points, usually.
I probably have the Python code available to fairly easily read a list
of lat/lon and calculate distance/bearing between each pair. What I
don't have is the knowledge to then plot that onto a sheet to a sheet to
create what looks like a survey map with boundaries and markers.
