After collecting all the street names, it's time to collect house numbers. What is the best mobile application to automate the process ? One possible workflow would be:

If you have an Android device:
During the first large test 214 housenumbers were collected in 42 minutes (One 3 digit number every 12 seconds). A subsequent review showed that 89% was correct. The remaing 11% had to be edited as to not confuse the geocoder / reverse geocoder. (Arranging the nodes in neat rows is beyond the scope of this exercise). I subsequently improved my productivity further by using addr:interpolation. |

On Windows Mobile I've used OSMtracker to enter custom text waypoints. If the number was on the left, I enter say "12," (or sometimes just "12") if it was on the right I'd enter ",15" and if recording numbers on both sides of the way at once I'd enter say "14,17". In your application (which I can't test) you'd need some way of entering text for houses which have addresses such as "36a" or for full text names in cases where houses are named but un-numbered (older parts of villages in this area). Do I understand correctly that entering "12," will not actually place the housenumber on the left ? Afterwards you need to inspect and place nearly every node ?

Yes, the waypoint will only ever be where the GPS records your position at the time you save the number. Were you thinking by specifying left or right in your workflow the app could perhaps offset the nodes by an entered distance (which might need reconfiguring for each road and depending which side you are walking down)? It's an interesting idea if so, but as you need to review anyway to allow for any GPS inaccuracies I'm not sure how much time it would save.

Yes. My post processor already offsets the node. After some testing I'll perhaps make the offset different for left and right.

If you have an iPhone: For this purpose I put the buttons "copy all tags" and "paste all tags" into iLOE. So it is only half automatic, but fast enough when on a walk outside. Insert the tags for one house in the street, then copy all the tags. Put all the tags for the next house and just change the housenumber. Then upload. Happy mapping, Johannes

Note that Nominatim (and possibly other geocoders) only need the addr:housenumber tag.
