Following along with great interest and glad to see that there are some here that understand what I want/need to do.
Now, for the "hitch" - I'm an engineer, but I don't use CAD. (they don't trust me with it? I don't even have it on my computer! LOL), so I have to get one of my CAD operators to do this for me and send me the resulting file that could be uploaded to a GPS unit. I can also ask my surveyor to help me convert files for this use.
I don't need a "plan" view on my GPS unit...all I'm really looking to do is take a general layout of right-of-ways, easements, and detention ponds - convert that to some basic polylines and then import to GPS.
To understand WHY I want to do this...I frequently have to clear trees from project sites, and I'm a woodworker. The contractor will clear all trees within the limits we set. Generally, they will come in, cut and sell the hardwood trees for lumber, and the pines for lumber or pulp - then burn everything else. On the project I'm working on right now - I've identified about 15-20 trees that interest me as a woodworker, but the contractor would just burn them.
So I'm trying to get into my jobsites and selectively cut down a few trees before my clearing contractor moves in.
