Can we can baseline the tagging based on color codes given on the NHAI map- http://upload.wikimedia.org/wikipedia/commons/f/f7/India_simplified_roadway_map.svg (big file)

Even 10,000 active mappers wont be enough to update the status of roads frequently. how many mappers would you expect who travel by road on 60000kms of national highways daily? While this can be done on heavily used nh's like the golden quad etc but its an impractical approach to follow for all the roads. I agree thats its really useful for motorists to know the condition of the road, but it would require a huge and highly unsustainable effort.

This is the kind of info that i would like to see as an overlay to the map, like how you have live traffic status in google maps. That said, i'm not telling you not to continue your work with nh67, but it would be impossible to replicate this approach on our huge network of highways whose length total more than 200,000kms (nh+sh).


I'm planning to give a session on osm at barcamp chennai this saturday, so it would be great if we can agree on something by then.

cheers

  not dedication - I travel these roads every day. So can update the condition
  daily. Which is the case with all of us - we maintain our areas. Currently
  there are about 10-12 active people in India, but soon there will be
  thousands - in that case daily updates of road conditions is possible. That
  is why we are better than google

  We all agree on expressways - no problem

  1. Trunk - connecting major cities. So we have to agree on major cities:

  metros - Mum, Chen, Del and Kol (maybe also bengaluru and hyderabad)

  2. Primary - connecting 2 tier cities to each other and to major cities

  2 tier cities: coimbatore, pune, madurai, mangalore, ahmedabad ...

  3. Secondary - connecting district headquarters to state capitals or other
  district headquarters

  4. Everything else tertiary or less

  This is regardless of who owns the road

  Within cities - just map using common sense - basically, size of the road and
  amount of usage.
