Forest service roads

[bnordgren]

Currently, OSM contains a whole lot of roads which may not be drivable, and it's hard to distinguish open from closed, passable from not, etc. I'd want to distinguish a few important items:

• Location and type of obstructions (gates, kelly humps, etc)
• Road status:
  • Open road sections
  • closed road (permanent)
  • closed road (seasonal)
  • whether a closed section is passable or not (possibly "what would it take to make the road passable?")
• The "effective date" of the above.

Very likely we will have to edit the roads in OSM to match an official source. I cannot see how to avoid duplication if we have both OSM and a different source displayed. Some potentially useful datasets to use:

• Motor Vehicle Use Map: Roads

• National Forest System Roads

• Motor Vehicle Use Map: Trails

• National Forest System Trails

• Recreation Area Activities

• Recreation Opportunities

These are described at: https://data.fs.usda.gov/geodata/edw/datasets.php?dsetCategory=transportation

Checked these data out. The trail dataset is not so useful because it is "in progress", and it appears that some forests may elect not to contribute data...notably forests within my area of interest. The FS roads layer seems to at least have roads, but only on the forest, so there are "islands" of road segments. These may be useful to identify which roads are open and closed throughout the year.

The FSTopo graphics have the trails I'm interested in. There is a separate download page for the features on FSTopos here:

The "Transportation Line" dataset seems to have both roads and trails. "Transportation Point" has gates, berms, etc. "RoadShield48 Point" has the labels for the roads. "RecFacility Point" has trailheads, campgrounds, etc.
