Re: Moab RMP maps - geek lesson enclosed

The Moab BLM office published some pretty good maps reflecting the details of the recent
management plan.

Specifically the maps show which trails are open, which are restricted to single track for MCs,
which are ATV only (btw the morons rejected the concept of 50" vehicles and stayed with a
"straddled vehicle" definition for ATVs so RZRs are not legal on 50" trails in Moab)

But I digress.

So here are the maps:
http://www.blm.gov/ut/st/en/fo/moab/rec … /copy.html

The first thing you may notice is they are two sizes 11x17 and 23xhuge.
Printing them will be a challenge.

I have a better idea.  Use them with your GPS.
Get OziExplorer and install the shareware version.

OziExplorer allows you to take a map, any map, scan it in and calibrate it so that you
can get reliable GPS routes and waypoints from it.

It took me about 30 minutes to load all of the Moab RMP maps and calibrate them.
Calibration simply means you select two points on the map and tell Oziexplorer the
exact lat/long of those coordinates.  Lucky for us they are printed on the map.

Now I can use the BLMs own maps to make sure I am going in the right places
using my GPS.

Now I have my suspicions that the BLM is not the greatest map making agency given
that I imported some of my own GPS track logs from actual rides and in some places
there is a severe shift from where these maps show a trail.  That indicates that they recorded
some of the trails using a GPS without waypoint averaging enables (dumbass).

So don't expect perfection but it is a much better solution that simply riding and getting tickets.

The trickiest area is around the dunes, lots of changes there an no signage.  And its patroled.
