After some back-and-forth consultation with the provider of the shapefile 
(Lynn, VP of the local horse riders association) regarding tagging 
considerations, I completed an upload after better understanding how these 
(largely equestrian) trails might be conflated with existing OSM data (which 
were pretty sparse, given the rural area).

If you wish to take a look at the area, it is 
https://www.osm.org/#map=16/49.0620/-123.9715 .  "Up now" (as Bill Maher says 
on HBO's Real Time) are what Lynn and I are calling v1, there will be a minor 
v2 update (some permissions and traffic mode tweaks, I may add better parking 
amenities, water sources, etc.) after Lynn answers my last few questions later 
this week.  Currently the trail data are tagged with four traffic modes [atv, 
bicycle, foot, horse], either designated (rare, as so is signage), permissive 
(largely) or yes (public roads or Crown Land, a minority of the curated area).  
There may still be some considerations for snowmobiles, and/or some 
tracktype=gradeX fine-tuning as well as more precise harmonization with the 
Trans Canada Trail, but largely speaking, OSM now has these data, named, with 
length (but not width) and sometimes with surface/tracktype=grade data.

Post upload, I did add some satellite-imagery-visible larger-scale areas like 
large landuse=meadows cleared in the timberland, wetland=swamps (complementing 
CanVec data) and several landuse=quarries, which are rather numerous in the 
area.  All in all, a nice little "beef up" to this part of Vancouver Island in 
OSM.  Makes me want to get on a horse or a mountain bike and get out there!  
(James, there are no "vulgar trail names," some of them are reminiscent of 
comic strip characters!)  A centrally-located (to the curated area) private 
inholding has all of its trails marked access=private, respecting the 
landowner's wishes to diminish trail use by riders who use widely-available 
maps (like OSM).

Lynn's initial reaction to seeing v1 tile was "I was quite pleased."  So except 
for the fine-tuning v2 we'll complete in a few days, Done!

If you live in the area and ride or hike here, you may now "smarten up" your 
phone or GPS with these named trails and very precise geo data.

OSM:  what a great project!

Hopefully the names of said trails are not so vulgar as past experiences.
If they have surveyed all of the trails themselves and are making the data
available, I don't see an issue with using it(other than it being grossly
inacurate)

[Talk-ca] A new available source of trail data in the Nanaimo area

[Doug Hembry]

Greetings..
I wanted to bring to the attention of Vancouver Island mappers a source of some 
trail data in the Nanaimo area that I don't feel competent to handle myself. On 
a recent vacation visit to friends in Nanaimo, I learned that an association 
called the Back Country Horsemen of British Columbia have surveyed many of 
their customary riding trails around McKay Lake, resulting in a shapefile that 
they are prepared to make available to OSM.

Originally, hearing about this shapefile, and expecting just a few trails 
clustered around the lake, I offered to import the data to OSM myself, but was 
surprised to find that it described quite a large network of trails covering a 
significant area. On reflection, given that I'm based in the SF Bay area in CA, 
and have zero local knowledge, I abandoned that idea. With the permission of my 
contact in the association, I'm asking if any local mappers might be interested 
in looking at the data with a view to importing it to OSM.

The GPS survey appears to have been carefully done, and displayed in JOSM it 
conforms closely to those parts of the trails that are visible in imagery. The 
downside is that information describing physical characteristics (type of 
highway: path, track, road?; width, surface, smoothness, etc) is mostly absent. 
As is information about permissions (horse, bike, ATVs, private or public, 
etc), jurisdiction, and supporting amenities (eg, car parks, signage, water). 
Some of the trails do have names.  So clearly some digging or surveying for the 
missing data would be necessary. (Possibly some association members might be 
willing to help, but I didn't bring up the possibility). But the point is, that 
this data describes real trails that are currently in use for equestrian 
recreation. And I believe (but am not certain) that the Trans-Canada trail 
(Great Trail?) intersects this trail network.

So that's it... Anyone who is interested in looking into this source should 
feel free to contact Lynn deVries of Back Country Horsemen of BC at 
nese...@gmail.com who can provide a copy of the 
shapefile.

Best..
