Re: [Tagging] How to tag house numbers based on decametres?
If it's only a problem of routing, wouldn't it be better to let the router do the job? The way would have to be tagged with something like numbering=distance, with the correct orientation (from start to end), and then it would be easy for a program to find out where #23 is. 2009/10/11 John Smith deltafoxtrot...@gmail.com 2009/10/11 SLXViper slxvi...@gmx.net: John Smith wrote: I can't think of a good solution for this, a few years ago they renumbered all properties along roads outside of residential areas to be the distance in decametres (10s of metres, 100m would be #10 etc) from the start of the road, they also have even on the right, odd on the left, this makes it easier for emergency services to find places because its based on distance. I doubt there would be an easy was to interpolate this information for display, but it could be used to work out end points for routing, and all we need to know is which end of a way is the start, the rest can be worked out. The universal solution for such special cases would be tagging single addresses without interpolation. This would provide information - what house numbers do actually exist? In this special case nearly every value could be possible. - where exactly is this house number? Since numbers are based on distance this could also be calculated from the given number - but what if want to know the house number of a given position? The only disadvantage of this method would be a little bit more work on the ground - but nothing photo mapping couldn't solve ;) As I stated, this sort of tagging wouldn't be that useful for displaying/rendering, but could be used for routing. If the routing engine is coded in a smart way, it could be used to collect the house numbers asked for and use that information to add street addressing. ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging

2009/10/12 Cartinus carti...@xs4all.nl: And how are you going to find the start and end of those sections without surveying? You won't, not unless you have some external data to import (and you didn't mention anything about that). Long sections of highways are an exception rather than the rule, and more likely to be travelled by someone that can fill int he blanks. I was thinking more about most roads in general, which in my experence the start of roads radiate out from localities, so educated guessing can be used for the most part. ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging

Not sure if you saw it before, but http://lists.openstreetmap.org/pipermail/tagging/2009-October/38.html Is that in agreement with what you'd like to see?

If we could get away with only survey 1 point every 100km we would have already have finished earth some years ago and be onto the next planet Quite true. I suspect you will need to survey which houses are nearest each road junction plus any gaps, I suspect surveying a few points every 100m is going to be nearer what you need. Need for what? The more survey points, the better. The accuracy gradually gets better and better as more points are added. Eventually you've surveyed every house - sort of: you'll probably never finish (unless all the postal services in the world decide to release their databases into the public domain), because while you were out surveying some more houses popped up. ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging

Not likely - easier to find the start and end - can do that by pestering the Council which is much easier than trying to survey for street numbers.

The population density is certainly not requiring a point every 100m to determine the rural road number, but as it is a mathematical function, it can be defined and used for a routing engine. ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
