There has been some discussion on the tagging list about what to do with rural road numbering. For people unaware there was a standard created to renumber rural roads to make it easier for services, especially emergency services, to locate properties. They used decametres (10s of metres) from some arbitary start point, usually from a locality outwards. Odds are always allocated to the left, and even numbers to the right.
While this won't be useful for rendering it would be potentially very useful for routing software, since the software just has to know the start point and estimate the approximate distance and then point to the left or right side of the road. Routing software could even be coded to collect all such requests to a central database, or the OSM DB directly to be used for rendering. This numbering scheme is published as an Australian/New Zealand Standard, AS/NZS 4724:2000 Geographic Information – Rural Addressing. Currently I'm thinking we could tag roads as numbering=as/nzs or something similar, and then the only problem then is how to tag the start/end of a numbering section, based on that standard major roads are broken up into sections of 100km. Liz found a document produced by Land Victoria, including some useful tips in section 6 on how councils could renumber properties safely may be useful for us. http://tinyurl.com/yhv7ady _______________________________________________ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au
