In the recent New Zealand wide address import, we ignored (deleted from import), most large sets of coincident address nodes like this. I.e. they have been left for a future update. Where there were less than about 10, and the assignment to units looked fairly obvious we spread them out. In a few cases, I used JOSM's 'distribute' to scatter them slightly. Possibly using https://wiki.openstreetmap.org/wiki/Key:addr:flats is a way forward for this situation. > Here's a sample of the addresses they have which I have sorted > ascending: > > ... snip ... 206/38-44 Pembroke Street 207/38-44 Pembroke Street > 208/38-44 Pembroke Street 210/38-44 Pembroke Street 212/38-44 > Pembroke Street 301/38-44 Pembroke Street 302A/38-44 Pembroke Street > 304/38-44 Pembroke Street 305/38-44 Pembroke Street 306/38-44 > Pembroke Street 306B/38-44 Pembroke Street 307/38-44 Pembroke Street > 310/38-44 Pembroke Street 401A/38-44 Pembroke Street 402A/38-44 > Pembroke Street ... snip ... > > As you can see: > > 1.

Continue the conservative displacement strategy, > or? One possibility for the example you give above would be to just map a single node at "38-44 Pembroke Street" I wonder if in-person survey would shed any light on how/where to places these addresses... -- Eliot _______________________________________________ Imports mailing list [email protected] https://lists.openstreetmap.org/listinfo/imports
