I want to make a computer map of my property (about 40 acres).
I am not interested in the actual legal property lines.
What I am interested in is drawing a map in some computer program of my walking path along my property lines.
So, my criteria are:
What do I use to get extremely accurate and repeatedly accurate coordinates?
How to I get this route into my computer?
And what program should I use to draw or plot this info on the computer screen?
