'Gravel' it isn't, rather it is boulders and sharp loose rocks with up to 2 foot drops. I made it to the bottom still on the bike but I think it is the closest I've ever come to dying on my bike. Up would probably be impossible, down is just stupid unless you are way better than I am. Is the best way to indicate you're legally allowed to cycle here but would be an idiot to try* to add an mtb:scale tag of 0, or is there some other accepted (by mappers and routers) way of doing this? I've previously added surface tags to the bits I've mapped around here but I wouldn't expect a router to understand random values in that. Hard to judge from the photos and I don't have the experience but I'd say a minimum of s3 maybe s4 due to the loose rocks on the bit I've linked. -- Brian ___ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb

Tom I've just tried searching osm.org for S42 7DT and the first answer is a street that is actually S42 7DY according to Chris's site. Is it perhaps just using the first S42 7## part? It does a search using the royal mail postcode but then returns only data found in OSM. It seems we might have lost the 'order by distance to the postcode' when I added the wikipedia importance code so it is now returning the 10 nearest roads in an arbitrary order. I'll try and get that fixed. I've always been concerned about merging the postcode data into the OSM output and lower lever indexing because of the uncertainty around the '© Royal Mail' part of the license. If this data is now being imported into OSM I assume I should now stop worrying about this?

There doesn't seem to be any consensus or guidelines about what to put in the name tag. Should it be Dartford or Dartford Borough or Borough of Dartford or Dartford Council or something else? Is it naming the area, or the administrative entity governing it? As there are very many cases of areas at many levels named identically, from counties down to parishes, there needs to be some way of distinguishing between them. We have to watch out that we continue to distinguish distinct, unrelated hierarchies. In particular parish and ward mean different things according to the context. There are civil parishes, which are (by definition) a subarea of a higher-level local authority (normally district/borough or unitary authority) and ecclesiastical parishes: each religion/denomination has its own hierarchy of areas. The NHS has a geographic hierarchy as has Fire and Rescue. But they have only a certain correlation to governmental areas, with cases of one fire service serving multiple counties, and a counties being covered by multiple fire services (although I don't have an example of this to hand). An area at admin level 10 might be a civil parish, it might be an ecclesiastical parish, it might be an electoral ward etc etc. To me, boundary=administrative means the boundary belongs to government, which means it starts at level 2 with countries (leaving room for supra-national levels such as the EU) and includes regions, counties, unitary authorities, districts and civil parishes. Wards in this hierarchy should really be at admin level 11 (i.e. inferior to parishes). There are some special cases which don't fit the 100%: the Scilly Isles and City of London spring to mind. There is a hierarchy of parliamentary-electoral areas as well; the lowest quantum is the ward but these are not the same as the wards for local council purposes. Personally, and as the maintainer of nominatim I would be very happy to see admin_level dropped in favour of a set of specific tags (i.e. place=* or something similar). Admin_level is applied inconsistently and in ways that cause overlapping hierarchies. They also correlate badly between the place nodes and boundary relations - using a consistent set of tags across both would help no end in parsing the data! The current version of nominatim starts the process of linking admin boundaries to nodes - the next version will probably depreciate admin_level in favour of the place=* value from the label node where it is available. -- Brian ___ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb
Re: [Talk-GB] Millennium Greens Doorstep Greens
Searching OSM for name=Millennium Green shows that these are currently mapped as: * parks * village greens * nature reserves * recreation grounds * common land To me it looks like leisure=park is best (with the others used only when the exact same land area is also designated as one of the other types, all of which seem to have some official meaning). However this does not cover the Millennium Green status - perhaps designation=millennium_green? Alternatively we tag an area as leisure=millennium_green or designation=millennium_green just round the designated area and leave the park/common/whatever tag on a separate way (e.g. Millennium Greens may comprise part of a larger open space). Millennium Greens cover a wide range of on the ground usages. Same are clearly gardens, some parks, some nature reserves. Please do not retag these features to some perceived standard. I would also avoid overloading the designation key - better to have an explicit key than to reuse and existing key. About the only thing these area have in common is that they were all funded as part of the same project, if you want capture this information I would suggest something like: millennium_green=yes or how about: funding_source=Millennium Green -- Brian ___ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb

They have to include significant natural area. The one closest to me is a mix of grassy areas and woodland. Oddly it misses one part of grassy area. There is a local nature reserve that includes all the grassed area but not the wood!! It would make sense to me to tag the whole area as leisure=park and then to tag the Millennium Green and Local Nature Reserve as 2 separate closed ways. The whole area isn't a park so don't tag it as such. It is an area covered by a funding program / financial trust. Perhaps the landuse tag can be used. The main issue here is that the area is Please do not reuse existing tags (designation, landuse, whatever) to mean something new. Create a new tag that is explicit. Reusing an existing tag causes huge problems for data users. It isn't a type of landuse - which describes the physical usage of the land. On second thoughts, there is a boundary proposal that could work well: http://wiki.openstreetmap.org/wiki/Proposed_features/Reserve#Examples Looks like the boundary tag is already used: http://wiki.openstreetmap.org/wiki/Tag:boundary%3Dnational_park http://wiki.openstreetmap.org/wiki/Tag:boundary%3Dprotected_area Looking at the page on boundary=protected_area, perhaps class 7 is the right one for Millennium Greens? As Ed has said this probably isn't appropriate although it would seem closer. How about boundary=millennium_green ? Please - use a new tag. Don't try to twist an existing tag. Adding a new tag is not a bad thing - create it and document what you have done to the wiki. -- Brian ___ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb

I think it's the bureaucracy that is the harder issue. It's the amount of admin required and finding someone that has the time to spend creating, maintaining the logos (and presumably getting permission to use them) and to create the rules. Also, the icons need to be of a certain quality (for mapnik certainly). As a one off it is trivial but... The other question is where do we stop? It's certainly a whole can of worms and once the first one is on the map it will be hard to stop it snowballing. My feeling is that someone keen should investigate this on this own map server before attempting anything like this on the official mapnik layer.

[Talk-GB] Rotherham mapping party this weekend (15th and 16th)
Hi, This is a notification / reminding that the Rotherham mapping party is happening this weekend. Due to recent mapping the focus of the party has shifted from central Rotherham to the West and surrounding areas - but there is still plenty to map!

Re: [Talk-GB] UK Boundaries - update
1) Complete the conversion from boundary=administrative - boundary=ceremonial for the ceremonial-only counties. I will do this and also change the name of these to 'Blar (ceremonial)' to make a clear distinction from the administrative boundary. Changing them to boundary=ceremonial is great, but can I request that you don't add '(ceremonial)' to the end? This is implicit in the tagging and it is generally easier to automatically add a postfix than to remove it. -- Brian ___ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb
Re: [Talk-GB] Address, post code data base
Hi, I ran a little script against the data base of planning applications of Islington Council and ended up with around 16,500 address. Around 6,500 of them are relatively old and only have the first part of the post code. After tidying the data little and removing dupes, this still leaves 10,000 Islington addresses with a fully qualified post code, available in a plain text file for your perusal. So I was wondering if others have done the same for their area, and how to best share this data. Has anybody experimented with address data bases yet? Is there a preferred file format? Is there a drop-off point anywhere? I've got a set of scripts that parse and try and match/import the data to a seperate postcode database. The plan was to make it available as a combination geo-coding service and bulk data upload. The command line scripts are mostly working and produce quite usable results most of the time but I had a large project turn up at work before I could quite finish it or get the public interface written. That's just coming to an end now so I was expecting to get back to it. Relevant thread here: http://www.mail-archive.com/talk-gb@openstreetmap.org/msg01291.html My feeling was that this data was best kept in a seperate database because it might not be that accurate (multiple streets with same name) and in case of any copyright problems - I was going to make it available as a seperate download like NPE / Postboxes / etc. I'd love a copy of your data to try feeding into the code I've got - could you email it / let me have a copy?

Mapping an area after it has been traced is: a) almost as much work as without the tracing (you still have to go down each road to look for missed features) b) very unsatisfying because it doesn't look like you have achieved anything I hate doing area that have been traced, I even hate doing areas that *I* have traced. It is however nice to fill in extra details that can only easily be done from aerial images like building outlines and other large features - I'd love to buy some aerial imagery for Sheffield for instance - but only once the basic mapping is *finished* please! Thinking ahead, should be set up an Aerial photography team who sort out the purchasing and hosting of commercial photography as and when required? I can see the point, but do this with great care please or I'm sure you will loose some dedicated mappers. -- Brian ___ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb
