My larger concern is the possibility of bad data.
You indicated that there are several areas in Idaho where the trails are "gone" does that mean rerouted, abandoned?
I know that we should never be totally dependent on our GPS's but several longer loop hikes could be really affected if a trail that you though existed really doesn't.
Also, I am suprized that we don't have highly accurate data in Tolt MacDonald. Maybe a trail mapping event should be in the works. I know that Prying Pandora was thinking of something similer in another area.

Per eraseek's post - if you can get the trail set into your software, then save as a .gpx, you can use GPS Babel to convert a .gpx to a Magellan track file - .log

Having something (even if the quality is suspect) is better than having nothing. I say we all just need to get out and validate it.
I like the trail mapping events idea. Yes, they could be events since the main purpose would not be to find caches. Of course if you happened to walk by one.... or two....
I also think segmenting the data would be good if it was easy to do. I assume it would work the same way as City Navigator does. I have plenty of storage space but it still takes time to reload as the updates come out (not that I mind).

The trails in the FSGeodata Clearinghouse seem to match almost exactly the trails (including abandoned railroads and some dirt roads) shown on USGS topo maps. That's great when you you are talking thoroughness of coverage, but as we all know most of the USGS topo maps are extremely outdated these days.
The trails I mentioned as "gone" are ones that have been abandoned and have been mostly reclaimed by nature. An example that I spotted in the Priest Lake area was the trail up to Squaw Mountain and the Wigwams. However, in some cases the trails shown have been rehabilitated and recovered. An example in the Priest Lake area is the Two Mouth Lakes Trail (the western approach from the lake).
A benefit I saw in the FSGeodata Clearinghouse data is that it includes areas around the NF lands, while the data off of the NFS main site stops at the forest borders. Also, since many of the forests have not put any GIS data of any sort up on their official sites, the Clearinghouse data includes all forests and thus helps fill in those areas in which other data is not yet available.
Overall, I saw it a benefit to add the Clearinghouse data, which is why I spent as much time as I did integrating it (it takes a lot of work to pull in the data and then try to weed out that data that duplicates better data from other sources, especially when you are talking the 90000+ segments of trails that are now included in the mapset). Perhaps coloring the non-GPS data with a different type style would help, but then I worry that the styles will become too large and confusing. No point needing to carry a legend card around with with you to figure out a trail type!
I'll throw together some ideas for breaking out the map into smaller tiles and post them here later for feedback.

That being the case I would say throw everything in. A trail reclaimed by nature is still usually a trail with lots of overgrowth. That answers my question.

This gets my vote. The great value I see in this project is knowing that someone has walked the route with a GPS. We know that the data is accurate, the trail really does exist, more or less in the location indicated. So, I really would like to see the "suspect" (not verified via GPS track) portions in a different color. Two different colors doesn't seem too confusing to me, but I see real value in distinguishing this data from what you collect via real tracks.
Just so you know, I haven't decided what's cooler - this project or the caching features of the Garmin Colorado. I think this project has the edge. It is turning into an amazing resource. While doing some suburban caching yesterday, I was surprised to see a nice little red trail show up. It confirmed the proper approach to a cache that I might have otherwise ignored. Way cool.
Edit: Okay, three colors - my eyes are so bad that I'd never noticed there was a maroon set distinct from red. Wow.

Looks good to me - probably more logical than by state.
I had to share this. I don't know if anyone else does this, but I use my Nuvi to navigate to trailheads, then my Colorado from there. It just now occurred to me that I could probably load these trail maps on the Nuvi as well - yup! They show up great, including the trailhead POIs - most valuable.

I like the size and general boudaries. Delimiting by county or grid line will not matter to me. Folks near a boundary will end up loading two tiles anyway.

My real questions here is how you'd like folks like myself that intend to field validate trail segments and/or document missing trails. I was going to just start from my HOME coords and work outwards. I don't see any easy way to report "such-n-such segment should be deleted - old abandoned road" situations. Maybe you don't intend to remove them from your map but simply to attribute them as to their current condition?
If there were a way to throw these segments up on something like Google Earth (I also have access to ArcView) it would really help to validate them. As it is, I have to keep toggling between map layers in MapSource. [Edited to clarify - I'm only speaking of sitting at home on the PC]
Here's an example close to my home - N43 22.974, W124 15.844 marks the north end of a "trail" segment that really doesn't exist anymore. US Topo calls it a "Trail" or "Pack Trail". It's neither a developed trail nor a navigitable road. Is this the kind of feedback you want?

I appreciate these free map projects undertaken by dedicated individuals but this is the reason why I encourage people to use OpenStreetMap. If you see a problem, you can fix it yourself and then you and everyone else can benefit. Check out mkgmap for creating Garmin maps from OSM data. Other projects are in the works, too.

Yes, that's great feedback! You can point out segments like you just did, or take a screenshot of the maps in MapSource and mark them up to send to me, or whatever works best for you. Another option would be to open the map in MapSource and create waypoints with notes at each trail segment that you are commenting on, then send me a GPX file of those waypoints.
I have removed the segment that you note above. It was from FSGeodata Clearinghouse, and I won't plan on ever reintegrating the data from that site again unless they have a major and thorough overhaul of the data.

- Added a background map so you can more easily locate a specific trail
- Broke the data out into six separate map tiles
I elected to break things out by state since it was simply easier to do and would make it easier for people to know offhand where the breaks are (even though state borders are often not the most logical delineation). The problem with this, as I discovered, is that it causes overlapping selection rectangles in Mapsource. The software apparently doesn't like this, so the selection rectangles are appearing quite undersized and tucked into the upper left or lower left corner of the state each covers. This only appears to be a visual problem in Mapsource, however, as in testing on my Colorado the entire data content for each state appears to be successfully downloading into the unit. I will start looking into solutions for this; one would be to pony up for the more expensive version of the map creation software that allows for irregular map bounds, and a cheaper one would be to break the data out into a regular rectangular grid.
Overall, the download size for version 1.05 has jumped to 14.3 MB from 8.1 MB for version 1.04, but that is virtually all due to the inclusion of a background map. Below is a list of the current sizes of the map tiles by state. Note that even the biggest is a fraction of the 9+ MB that the single map tile in version 1.04 came to, so people should be able to pick and choose what data they want and have a much smaller impact on their map memory now.
- BC: 24 KB
- ID: 3.34 MB
- MT: 2.85 MB
- OR: 1.55 MB
- WA: 2.01 MB
- WY: 1.38 MB
Here is the complete list of changes in version 1.05:
- Broke trail data into six separate map tiles by state/province
(Note that the software doesn't seem to like the overlapping map selection boxes that result from this, which is causing the selection boxes to appear vastly undersized and placed in the upper or lower left corner of the state that each covers. In my tests on my Colorado, however, all of the data for each state is getting succesfully downloaded to the unit even though the bounding boxes don't appear to cover the entire extent of the data.) - Added background map to help with location and orientation
- Corrected some trail names in the Redmond Watershed
- Removed a trail on Radar Hill near Coos Bay, Oregon that was confirmed by popop as no longer present
- Added GPS data:
- Keeney Neighborhood Park (Bellevue, WA)
- Powerline trail leading into Bridal Trails State Park (WA)
- Keeney Neighborhood Park (Bellevue, WA)
- Added GPS data courtesy of FunnyNose:
- Lincoln Park (Seattle, WA)
- Added GPS data courtesy of dsvaughn:
- Klahanie neighborhood trails near Horse Lake (Sammamish, WA)
