When OSM was starting up and android phones with onboard GPS weren't yet commonplace, I saw OSM enthusiasts like the folks at Homi Bhabha Centre for Science using GPS devices to record the trace on their journey and then transferring the trace to computer and uploading the trace to OSM.
Now when GPS devices are commonplace and every other person is a potential contributor, I'm not sure there's that much enthusiasm to trace the roads and upload them to OSM. I agree with not wanting to re-invent the wheel, but depending only on top-down sources (which btw would even have the roads in remote areas that exist only on paper or are in disrepair) and not putting any energy into nurturing bottom-up ways might not be a good idea. So how about going interdisciplinary with this: Popularize the apps that make it easy for regular people to contribute. Orgs taking this up as a project can get interns to go on field and cover all the roads in a dark (on OSM ie) area. A cycling championship could be done where the prize goes to the contestant who covered the most amount of yet-unmarked kms of roads in a given timeframe. Cycling enthusiast groups can find unmapped areas to decide the next expedition and cover them. So working on making the contributing of GPS traces and such data to OSM easier for regular people might also be a good long term strategy for increasing the coverage. -- Cheers, Nikhil +91-966-583-1250 Pune, India Self-designed learner at Swaraj University <http://www.swarajuniversity.org> http://nikhilsheth.blogspot.in On Wed, Nov 25, 2015 at 10:48 PM, Justin Meyers < justinelliotmey...@gmail.com> wrote: > That example was for Maharashtra > > > On Wednesday, November 25, 2015 at 12:17:56 PM UTC-5, Justin Meyers wrote: >> >> Here is a extract of OSM road features vs Govt data. >> osm - 99,002,845 meters >> govt - 243,678,394 meters >> >> >> >> On Tuesday, November 24, 2015 at 5:45:59 AM UTC-5, Arun Ganesh wrote: >>> >>> India has one of the lowest road coverage in OSM according to the recent >>> data metrics report: https://www.mapbox.com/data-platform/country/#india >>> .
