Hi all,
I've created a set of tiles from US Forest Service road data for the 155
US National Forests.
This is to help with TIGER fixup in these rural areas, where tracks,
trails and entirely non-existent paths are often tagged with a bare
"highway=residential". The US Forest Service data is greatly superior to
the original TIGER data and has metadata on surface type/quality, but is
unsuitable for automatic import into OSM because it would overwrite
mappers' existing work in these areas.
You can access the tiles at:
Potlatch 2/JOSM - http://osm.cycle.travel/forest/{zoom}/{x}/{y}.png
iD - http://osm.cycle.travel/forest/{z}/{x}/{y}.png
and they're included in the editor-imagery-index list used by P2 and iD.
The tiles are available up to z19. Use of Potlatch 2's new "floating
imagery window" mode is recommended, so that you can work from both Bing
imagery and these tiles at the same time. :)
You can also explore from the comfort of your browser:
http://osm.cycle.travel/index.html
where there's an "Edit this area in OpenStreetMap" link at the bottom right.
The key is:
Surface:
yellow outline = paved
grey outline = gravel
Road type:
white with black casing = paved road
dashed grey = gravel road suitable for cars
dashed brown = dirt road
dotted grey = not maintained for cars
Maintenance level:
grey dots = 4x4 only
green dots = usable by cars
black dots = moderately comfortable for cars
black frequent dots = very comfortable for cars
Points of interest:
car = roadside park
flag = Forest Service station
ski = winter recreation area
hiker = trailhead
campsite = campsite
picnic site = picnic site
(There's some degree of overlap, but this is present in the original
USFS data.)
When remapping, I would suggest the following tags as a minimum:
highway=unclassified - paved road
highway=unclassified, surface=unpaved/gravel/dirt - unpaved road
suitable for cars
highway=service - road to isolated dwelling or other building
highway=track - unpaved track or road suitable for 4x4s
highway=path - narrow linear clearing, too narrow for motor vehicles
[delete entirely] - raw TIGER data with no signs of track or path in
either imagery or Forest Service tiles
US Forest Service data is public domain so there's no need for further
attribution when using this data, though a source= tag is always good
practice.
Hope these are helpful, and let me know of any further suggestions.
cheers
Richard
