-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Yeah, the method of including the various admin level distric pcodes in the settlement pcode was discussed by the group when they were generating them, but they decided against it for exactly the reason you stated, boundaries change over time.
Regarding the merge itself, it does seem like the script method would be more robust for sure. Just to avoid duplicating any previous work, do you (or anyone else) know of such a script? Our plan was basically going to be to write one from scratch but if such a thing already exists (or something close) it makes a lot more sense to use that. - -AndrewBuck On 09/24/2014 03:09 PM, Severin Menard wrote: > Hi Andrew, > > I agree taht pairing the OSM Ids will be the most simple and > robust solution.
