Hi its probably been asked many times before but what to do with unnamed roads I’m working on an area centered on blarney (but it seems quite universal in Ireland)
It’s common for a road not to have a name even the ones with houses on. quite often you will see things like wooodfield estate. several roads and blocks of houses no names. Often there are roads with no names that just meander from hamlet to hamlet again no name. then the places where are the places this cluster of houses or is it that bit up the road. Seems that you just have area’s with no set boundaries.
How should I map area’s like that? leave them red or call them fixme like the last guy did with the roads he mapped. Even looking at yahoo or google or the ordinance survey theres no methodology and often different names appearing in similar places. TomTom is even worse with just principal area’s and major routes.
I’d appreciate any advice especially from mappers in ireland.
Should have known I was opening a can of worms, and its difficult even stating the problem.
1)A road has a name and the mapper knows and adds it.
2)A road doesn’t have a name and the mapper is certain of that.
3)A road might have a name or it might not but its unknown to the mapper
4)A road might not have a name now but it gets one in the future.
you can substitute place for road and it’s the same cases.
although when does a hamlet become a village or a town or a city.
Actually there is a solution to finding a place but it seems to be a commercial solution thats going to cost a lot of money to use it. http://irishpostcodes.ie/ and as its based on Gps position it could be hard to work around.
That’s fine, this is how most roads are given names in OSM.
As emj said, put a noname tag on or put “Road is unnamed” in the note tag.
Leave it untagged OR if the road has already been tagged, put fixme=noname
This isn’t a problem, tag it as (2) and when the road is named another mapper will add the name. OSM will never be entirely complete, it’s a work in progress.
I don’t know about Ireland, but in the UK a hamlet is a village without a church. A village is a place with a church. A town is a place not designated as a city. A city is a town with a Cathedral or granted letters patent at some point in history. I imagine it’s largely the same in Ireland.
You can’t use that commercial website even if you are willing to pay: you’d be in breach of their copyright.
I really have issues with that irishpostcodes.ie site Ireland doesn’t have postcodes yet but they are coming via that website essentially they have a 7 digit code to identify any particular area its based on the actual latitude and longitude and their licensing it. You can’t use it in your website or application without licensing it. That means we can’t use it and probably further down the line we will be having to figure out or collect postcodes the same as in the UK. Any large scale collection is going to create legal issues.
However there is one solution http://geohash.org/ now that does a similar thing it encodes latitude and longitude into base 32 (5bits per digit, and weaves them together by making odd bits latitude and even longitude (or the other way round) the cute thing about it is that he’s handled the issue of accuracy by treating it like analog to digital conversion basically each bit increases the accuracy so roughly the first bit determines if its less or more than 45 degree’s then splits that to more or less than 22.5 degrees eventually refining to within about a meter or so for a short code you might use to identify London roughly then a bit more to locate chelsea then chelsea bridge and then one end of the bridge from the other. So really its up to you how accurate you want the location. it’s also a unique code for the whole world regardless of borders regions and administrative area’s it’s got great potential from individual use to international parcel couriers .
there’s a basic java class for the encoding and decoding (other languages too) and it didn’t take long to create a swing interface to encode and decode the coordinates.
While it works I think the next thing would to be able to create a bounding box based on the accuracy of the geohash given.
The system has been placed by the author in the public domain so no one can claim exclusive rights to the codes.
That could be risky. I remember having seen a patented algorithm in 1997±3years proposing this kind of bit-interleaving to create indices expressing some kind of “nearness” in multidimensional data. But I don’t remember the details
