Yes, this is the case, you should go and check the stops in question. If there is physical evidence that buses stop there, it should be upgraded to a highway=bus_stop ___ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb

The SCO stuff a few years ago spring to mind. I'm wondering who has actually made there subscription charge for this data, and I wonder how long it will be before loads of Local Councils are having trouble with Council Tax and deciding which school is the closest.

[Talk-GB] Announcement - OS 1:25k mapping availability for OSM data contributors
We are all used to drawing in difficult or far away features by referring to the NPE 1" to 1 mile out of copyright Ordnance Survey mapping in JOSM or Potlatch. Its great for long linear features but for accurate stuff, like field boundaries and detailed information about the landscape, especially in rural areas, it's not enough. Enter the OS 1:25,000 scale (two and a half inches to the mile) 1st/Provisional edition [1]. Which I'm happy to announce is starting to make an appearance for the project. There are two parts to the availability currently. One focused on providing it via WMS for use in JOSM and the other as tiles for Potlatch. The first full sheet (NX88 NW or Dumfries [2]) is available for you to try out in JOSM [3]. Just add the URL as a custom WMS. For the Potlatch tiles RichardF has worked up some code magic that should automate the process of rectification and tiling. It may take me a little time to get that running and the tiles will probably be served from the new dev machine which is not quite ready yet so there will be a further announcement on this. Both the WMS and google format tiles use the same rectification data. The time consuming part is manually obtaining the pixel co-ordinates for the corner gridlines of each sheet (which I have to scan in two halves on my A3 scanner). It has to be done manually to get the best accuracy, which should be generally 10m once available in Potlatch or JOSM. i.e. significantly better than was possible with NPE, though note that its still only as good as the OS originally survey it in the late 19th century. Anyway, it means that this part is a slow process. Currently I have around 15% of the published sheets with more arriving every day. More would be welcome, either by way of donated maps, scans, or funds to purchase more from retail suppliers (higher cost - usually about £3 to £8 each). With 2027 sheets in the series cost is a factor for how quickly I can grow the set. I'll keep the index updated on the wiki with progress (both obtaining and scanning/tiling) so look out for your area turning up. The majority of the sheets I have are for England and Wales. Scotland never had full coverage from this series.

Its "a clean rewrite of the Job Centre Plus government website, allowing job seekers to quickly and easily find jobs by keyword within their local area, and subscribe to email alerts to future additions." The site was a good example of why we should have free access to postcode data. I came across a link to a presentation they gave at rewirdedstate.org"national hack the government day" - http://blip.tv/file/1853120/ I wonder if Royal Mail would go after councils and government departments who have failed to pay or keep up with their subscriptions. Its probably not a good idea to send threatening letters to bodies who could successfully lobby for things to be changed. Hopefully this might result in some advertising for free-the-postcode, and its aims Jason ___ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb
[Talk-GB] Ordnance Survey 7th series available
I am pleased to announce that the first of the OS 7th series out-of-copyright maps are available for use in OSM. Very brief details of the sheets and how to access them is available on the wiki at http://wiki.openstreetmap.org/wiki/7th_Series Thanks to TimSC for rectification work and setting up for WMS for JOSM, and to Richard for the Potlatch link. Those available are just the first of the 23 that are out-of-copyright right now, mainly in Scotland. More shortly. This is an ongoing project, and more sheets will be available to use a) as they come out of copyright, and b) are rectified and tiled. Any problems please contact me.

I have noticed that the status of some of the roads seem to have changed in Dumfries, so I think that local knowledge would be useful for this one. I've noticed that there is an offset in Dumfries that is noticeable (the current data is based on GPS). I've not checked to see how widespread the problem is.

If you can quantify any displacement it would be useful. We intend to try to check this and see if any improvements can be made to the process.

Another thought - is the displacement constant across the sheet? I've noticed with the NPE sheets that some parts of one sheet are offset one way relative to GPS data, whereas a couple of miles away there's a different offset (and it doesn't look like a sheet fold / not flat issue). ___ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb

Over the other side of the region in Newton Stewart there's a pretty good match between some GPS traces I took last year and the scans: http://www.openstreetmap.org/trace/152649/view Some of the streets in Newton Stewart itself look a bit out, but it's not that consistent -- looks more like a poor fix. ___ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb
