I have drawn my first road. It may be wrong but I am welcome to be corrected!

Location: Medavakkam, Isha Garden, Kanchipuram, Thiruvallur, India

I can't judge classification or quality of roads (as I don't know the road in real life) but I do see a little problem.

Your ways are not connected. Although the ways are close to each other, they do not share a node. A routing app will not know that you can go from Sivagami Nagar, Third Street to Sivagami Nagar, First Street.ยต

To connect two ways, you should do the following:

  • Drag the point that has to be the connecion a bit further from the other road (so yu have space to work).
  • click on that node you dragged away and see that your way is extending.
  • Finish off your way ON the other road (by double click, you need to aim very precisely on the other road).
  • You should now see that the connection node is bigger than other nodes of this road.
  • You can now delete that node you dragged away in the first step (or align it with the road).

Do this with all nodes that are connections between roads.

If you're doubting about classification of roads (I can't help with that), it's best to look at local documentation. So for you: http://wiki.openstreetmap.org/wiki/India:Tags/Highway

Other documentation you might want to read is the beginner's guide: http://wiki.openstreetmap.org/wiki/Beginners_Guide (mainly the part about editing maps and editing data)

If you have questions, do send me a message.

Oh, and I forgot to thank you for your data.

It's always nice to see people from regions with bad OSM data getting active on OSM.

Just a tips in addition to Sander's comments. In Potlatch you can connect two ways by doing the following: * click on the way you want to connect * drag the node at the end of the way on top of the other way * press "J" (like "join") * you should now see that the connection node is bigger than other nodes of this road.

BTW, you usually don't need to fill all the information on the street. If it's the "standard" value, you don't need to mention it. For instance, if it's allowed to go in both direction on the street, it's usual to not mention anything about "oneway". "oneway=no" is fine, but not necessary. Same goes for motor_vehicles, access, foot, maxspeed...

Have fun editing :-)

Thank you so much @Sanderd17 and @pieleric I was struggling with that. Now I became clear!
