....can you load GPX files into your TomTom via computer ?
If so, you can load the entire GPX forest service polygons (as tracks) into the existing GPS, and there you go.
I always update my GPS with Forest Service vector boundaries (essentially, polygons, or a track, made up of tens of thousands of connected points to form the National Forest service boundary of any single Unit). The USFS inventory is a massive one, well over 2 gigabytes in size.
What I do specifically is:
-using the USDA Forest Service data portal,
here--> I draw a polygon around a single Forest Service boundary I am interested in, and select: shapefile as the file download.
-using a shapefile to GPX converter, I convert the shapefile into a file any GPS can read: .GPX
-I then connect my GPS (or several GPSes to my laptop, and copy that GPX file into the appropriate folder inside the GPS
-then, I turn the Forest Service layer on inside my GPS so it shows up on my GPS screen.
I believe that certain specialized GPS data vendors (like National Geographic? Or, LeadDog Consulting) sell National Forest Service boundaries State by State in their software packages (as a part of a larger thematic endeavor). However, if you want the entire contiguous USA Forest Service boundary files for GPS, this could get costly ! Does anyone here know of one massive single GPS file encompassing all the USFS inventory ??
I've often thought of extracting every USFS boundary, and packaging it for GPS as a stand-alone layer...one day!
