[OSM-talk] Administrative boundaries (UK)
I wonder from where most people obtain their administrative boundaries to digitise for OSM? The most prevalent source is Ordnance Survey, but that current data is copyrighted, of course. I am particularly interested in civil parish boundaries, then in local authority boundaries to build up areas of interest and coverage. Can anyone help?

Hi Bob, Use the information on the ground. You will usually find signs welcoming you to the new area. It may be a few hundred metres either side, so look for the change in tar quality. You may also find that bin mapping is an option since the council often puts their name on the bins. (In Ireland you need to do bin mapping to get the names of the streets, rather than the boundaries).

Re: [OSM-talk] Administrative boundaries (UK)
I've managed to map county boundaries from signs like "Welcome to ..." and other features like it runs along a river. Some boundaries can be taken from out-of-copyright maps because they haven't changed. I too would like to draw parish boundaries but I have no luck with any non-copyright source yet. I hope you find something useful. cheers, Chris - Original Message From: Bob Hawkins <[EMAIL PROTECTED]> To: talk@openstreetmap.org Sent: Monday, 25 August, 2008 2:45:49 PM Subject: [OSM-talk] Administrative boundaries (UK) I wonder from where most people obtain their administrative boundaries to digitise for OSM?

I was amazed to find how little of the county boundary had changed in the past 50 years. I would use local knowledge and a variety of current (possibly copyright) sources to see if the old OS maps were still current and then digitise off the old maps. For my county the majority of the boundary was along rivers anyway (which I also entered from old OS (NPE) maps. The borough boundary however defeated me; It has changed considerably and for the majority doesn't follow any recognisable features on the ground so I don't have any usable source for that at the moment and have left it alone. It is possible that where it is not clear that it doesn't really matter much anyway (certainly not 200 meters either way), and that where it is in urban areas one should be able to get it on or between the appropriate roads. I might return to the borough boundary some time and have another go. I might ask a borough councillor to draw the boundary on my paper map and then transcribe it.

Agreed, except it tends to break down for the big urban centres where the original county boundaries made way for the metropolitan districts. I can bring the county boundaries into Birmingham from NPE very easily but defining the boundaries within the urban area for Birmingham, Sandwell, Walsall, Solihull etc needs the bin and recycle box approach, which I have to say works remarkably well.

In my council the council puts its name and the old parish name (no longer existing formally) on street signs. Elsewhere you're stuck with common knowledge (eg the boundary goes along the river) or out of copyright maps with a lot of double checking on historical changes (abolition/merging of areas etc - where that hasn't happened boundaries seem to stay pretty stable).
