[OSM-talk] City with completed housenumbering?

[Nic Roets]

Hello Matthias,

I'm working quite hard on the house numbers of Pretoria (South
Africa). I guess I collect a similar number of houses (around 22,000
numbers) since starting 2 months ago. But I admit my quality will be
much lower. I just visit the 2 endpoints of each street and then use
addr:interpolation. Quite often I use 'even' or 'odd' interpolation
when the numbers increase 4 between properties.

Another disadvantage of my approach is not splitting the interpolation
way where it crosses another street. The drawback will be that OSM
based SatNavs may get the last turn wrong (e.g. "Turn left and stop"
instead of "Turn right").
