Re: [HOT] Epworth Field Papers - The Zimbabwe Connection. Advice on JOSM categorisation.
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Rupert, What would really help us in this discussion is a few examples each of the various kinds of addresses. If you could provide us with the full text for a few addresses (all the way out to the country level), and a description of what they mean (if that is not obvious from the address itself), then we could give you better feedback. OSM already supports a great many address formats from around the world, so it is likely there are already others similar to these ones you describe. My guess is that you are going to want to put all of the information in tags like addr:block, address:neighbourhood, address:housenumber, and address:housename as the various ones. For local Chief's houses and things like that, the idea of the amenity=townhall tag has been proposed as well, but I think this is maybe not the best tag. In any case, these things have been considered somewhat and would greatly benefit from a better local understanding of the context surrounding these terms and the social significance of these places. We understand what tagging exists in OSM but we know little about how people who live in these places actually find their way around and use the address system they have. Without this understanding it is difficult to say which of the addressing schemes makes the most sense. - -AndrewBuck On 06/11/2015 04:03 PM, Rupert Allan wrote: Hi All, I'm Rupert, and I work with MSF as Field Mapping Coordinator.

Re: [HOT] Epworth Field Papers - The Zimbabwe Connection. Advice on JOSM categorisation.
Hello Rupert, The first thing to do in my opinion would be to add a proposed structure for Zimbabwe to the wiki page for administrative boundaries at the openstreetmap wiki: - https://wiki.openstreetmap.org/wiki/Tag:boundary%3Dadministrative Another possible source that would give you some idea is free the postcode http://wiki.openstreetmap.org/wiki/Free_The_Postcode you might be able to look at the blocks in a postal-code like way. When you tag the block identification in a postal-code like way on individual addresses, you can use standard GIS techniques like voronoy to regenerate the blocks from the individual addresses and at the same time check for anomalies. - http://wiki.openstreetmap.org/wiki/Free_The_Postcode - http://my2iu.blogspot.nl/2012/02/february-2012-go-transit-zone-map.html (explains using voronoi, to get a general idea) So in my opinion, you have two choices; - Generate blocks at an administrative level of your choice first and automatically add block info to addresses or - Enter block information as tags to addresses and analyse and correct afterwards. Hope this helps. Kind regards, Milo 2015-06-11 23:03 GMT+02:00 Rupert Allan m...@rupertallan.com: Hi All, I'm Rupert, and I work with MSF as Field Mapping Coordinator.
