I realize that not all linetypes are visible in all GPS units.
Since map development is easiest when I can see my results quickly, using BaseCamp is a great tool to see my results without having to download .img files to my GPS every 10 minutes.
Do any of you 'mappers' have a TEST MAP file containing ALL POSSIBLE LINETYPES so I can use it and view in BaseCamp, or any GPS device to determine a USEFUL SET of visible LINETYPES. I think this would be a good to for mappers to have, otherwise, every time you want to add a new linetype, you have to see if it is visible in BaseCamp (or whatever software you are using) AND you need to verify that linetype is also visible in your GPS unit.
I realize this 'test area' would have to exists in 1 location in the world, but you could make in the the ocean somewhere and just give coordinates so other mappers can find it.
