OpenStreetMap
I noticed that there were New York Long Path blazes when I went out a week ago (2016-04-24) to map the Wolf Creek Falls Preserve. (Actually, I knew in advance that they were there…) That made me remember that mapping the northern part of the Long Path ought to be a project. There are essentially no really good trail maps available of this trail from Huntersfield Mountain in the northern Catskills through the Schoharie Valley to its terminus (Thacher Park or Northville, according to whether you want to take it all the way to the Adirondacks). OSM has the opportunity to fix that.
I’ve started adding roadwalk and overlaid trails to the route relation, and posting notes for the missing sections. If nobody else does it, I’ll get out and GPS the missing sections at some point, but no real promise when that will happen.

Have you checked for Strava gpx points? If it is an active trail, it is likely someone used the Strava app.

I don’t have the Strava app (or an account for same), and recall being rather put off it when it asked permission to download my private contact list. Alltrails and Everytrail have nothing on the missing bits.

I don’t think you need a Strava account to use the data for mapping. They provide their data as a heatmap of points. They also have a fork of ID that includes a nifty function called Slide that allows aligning of ways to their heatmap. See: http://wiki.openstreetmap.org/wiki/Strava

Ah! That’ll help for a section or two. Some of the sections have no points on Strava, or a thin enough covering that I’m not sure I trust it. But there’s at least one missing section that I can trace from there, so thanks!

http://labs.strava.com/heatmap/#14/-74.16411/42.53240/blue/both is the sort of coverage I see for trails that I have mapped. There were a few runners doing a few pieces of that preserve, but most of the trails were unvisited. A hiker would consider them ‘active.’
