Yes, the TIGER problem is, but I don't think missing (or wrong due to physical abandonment) is a US-only problem. For cycling stuff I'm mostly ensuring that mountain bike-specific trails are in OSM and properly tagged (eg: highway=path and NOT highway=cycleway as some are wont to do), with appropriate intersection markers, names, etc. My goal is to ensure that these trails are in OSM so they'll flow down to Garmin, Trailforks, Mapbox / Strava, etc. I also use the OSM data, exported to vectors, to make PDF maps to support the local trail advocacy/building org that I'm part of. As examples, check out my edit history: https://www.openstreetmap.org/user/c0nsumer/history#map=7/44.608/-85.273 https://www.openstreetmap.org/user/c0nsumer/history#map=7/44... Here's examples of the print maps I've made. Versions of these hang at many trailheads in southeast Michigan: 1: http://www.cramba.org/storage/maps/stonycreek/CRAMBA_Stony_Creek_07-Jul-2015.pdf http://www.cramba.org/storage/maps/stonycreek/CRAMBA_Stony_C... 2: http://www.cramba.org/storage/maps/pontiaclake/CRAMBA_Pontiac_Lake_17-Jun-2014.pdf http://www.cramba.org/storage/maps/pontiaclake/CRAMBA_Pontia... 3: http://www.cramba.org/storage/maps/riverbends/CRAMBA_River_Bends_Trail_Map_2019-Sep-05.pdf http://www.cramba.org/storage/maps/riverbends/CRAMBA_River_B... Print maps are made using osm2ai.pl to get the routes into Adobe Illustrator (AI) format. I then stylize things there. I know I could use GIS software, but QGIS is a pain to get things looking the way I want (similar to Michigan DNR maps) and ArcGIS is too expensive for unpaid volunteer work. It's also way more hand-off-able in AI format; I can send the files to any graphic designer and they can keep-on with it. GIS software requires far more specialized knowledge.
