Re: [Talk-GB] Magistrates and Crown Courts listings as open data – hack event coming…
When listing such in newspapers or using online sites, they occasionally list the postcode/street, but not always. With post codes, it's often quite easy to find for a particular street or house number. A quick type of the name of the street and house number into Google will often bring back hundreds of results listing properties for sale, house numbers, electoral roll, etc. Often in this case, I've even seen listing of crimes commited by residences of a particular street (you can find out who if you pay). So I'm guessing more than likely the information will have this.

[Talk-GB] Question regarding OS Opendata
Hi I have a question regarding the OS Opendata. How accurately aligned is it? I've noticed that in some places the bing orphophotos match up almost perfectly to the buildings below, and it other areas there can be some difference (sometimes up to a meter of). Taking into account the angle the photo was taken from the air, and ground elevation, which should be considered more accurate? Generally, when adding buildings I trace the outline of the building on opendata, and then using bing aerial, I split the building shape up and add details. I generally have to continually align the bing aerial photo scenery to match the areas on opendata. Even on small areas, the differences can be quite a bit, and I'm doing my best to continually align and adjust. I'm asking (questioning accuracy), since the opendata seems pretty old, forested areas aren't often shaped or are missing and buildings are often missing. Whilst the orphophotos are also fairly old, they still seem more up-to-date in some areas. Regards Tony ___ Talk-GB mailing list Talk-GB@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-gb
Re: [Talk-GB] Question regarding OS Opendata
Thanks for the information. With regards to buildings, What I mean is that normally I add both an OpenData transparent layer and the bing layer in JOSM, and can see that sometimes they align quite nicely, and sometimes there is a noticable difference. People seem to generally map buildings using the bing layer without any alignment, or taking parallax into account. Generally I like to believe that the ordnance survery data is more correct, but sometimes it contains large errors, such as missing, badly shaped forests or completely missing buildings. I'm guessing it's quite difficult to get it really accurate, even when using a GPS, so I guess it's best to stick to whichever is the most accurate.

Re: [Talk-GB] Possible vandalism? New Forth Road Bridge being changed to motorway from construction
Hi Donald I had a similar problem with a user adding random buildings to places that don't exist, as well as really badly mapped areas with intersecting/crossing buildings and incorrectly tagged areas. the user in question never got back to me. It seems to me like he was using OSM as a sandbox, to play around. I've often thought that maybe schools are using it for student projects, or something similar. I'm not sure how to deal with this, apart from reverting the changes. Seems to me like some sort of moderation is needed on OSM, or at least a grading system. i.e. Once a user has done enough contributions which have been approved, you no longer need approval. In practice, something like this would be very hard to implement.

[Talk-GB] 2014 OS OpenData
Hi All Does anyone know how recent the OS StreetView data is, and if/when the update cycle is for the datasource in JOSM? I received an email from OS this morning about the release of the new 2014 maps, but it seems to me the OS StreetView data is maybe 2-3 years old now, and it some parts maybe unreliable. I've been using it to trace farms, rivers, ponds etc, so this data is fairly static, but I have noticed areas that seem quite out of date.

Actually, this type of import would have been very useful for my own project which uses OSM data for 3D maps. I was a little miffed to see it was simply reverted with no discussion. Good detailed data such as this is lacking very much in the UK, and we're very far behind other countries such as Germany. This sort of action I fear only scares others off from doing the same thing.

[Talk-GB] Tagging Residential & Retail zones
Hi All How do people normally go about tagging a landuse area which has both residential and retail buildings. In many areas buildings often are both residential and retail, in that the upstairs areas are rented apartments, and the downstairs is shop. I'm not sure how to go about correctly tagging the surrounding landuse, but so far I've been doing it predominately on what the majority of the buildings are, i.e. If the majority of the buildings and shops then the area is retail, etc. Tony ___ Talk-GB mailing list Talk-GB@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-gb

Re: [Talk-GB] Road Names Quarterly Project
I've seen numerous examples of this in OS OpenData, including fields marked up as woodland (which aren't on their paid paper maps), also they move things out of the way, e.g. buildings and drains to make way for the roads. Also, if anyone has used the OS VectorData to any extent, they'll notice it's also been altered (simplified) unnecessarily, or random things have been omitted for no apparent reason, e.g. large ponds, whilst the small ones are included. It almost seems to me that the OpenData is purposely created this way to limit its usefulness (e.g. No vector version of StreetView, missing tracks (but they include historical roman roads??), so they've done the absolute minimum to make their data open. Compared with other countries who offer all of their data for public use, it's pretty sad unfortunately. I think it's safe to say that OS OpenData should not be used as an authoritative source.

Re: [Talk-GB] New OS open data now available
Hi All Just had a quick look at the OpenData, in summary: -> Buildings are slightly more detailed, basically vector versions of the one on the streetview raster map -> All of the rest, forests, rivers, are no different than the current Vector data we already have (AFAIK). Forests,rivers etc are the same size as the older data. -> Roads seem to include a few more details, but not enough detail on them for accurate usage in OSM. So basically, it gives us slightly improved buildings, but they are still highly simplified in terms of their pay for products.

Re: [Talk-GB] New OS open data now available
I've just checked the buildings shape file, and every single entry has the same feature code unfortunately, the same with woodland. There is however a functional site shape file which gives outlines of where some key buildings are, along with their names, e.g. Schools, Hospitals. So this will be useful. In the download I did (OpenMap), the waterways weren't connected, but there is a separate download of water features which might be better quality. I'll give it a try shortly and see if it's any better. Tony On 24 March 2015 at 19:34, Rob Nickerson wrote: > My understanding was that the river dataset is now fully connected (and > wasn't before).

Re: [Talk-GB] New OS open data now available
Hi All The river network download is country wide, and does include connecting node information, along with the names. The data is much better quality and more accurate than some of the older imported stuff in OSM. It only includes major rivers and streams and is simplified, it does not include drains, etc.. The road download is also country wide, it includes connecting node information and also the names of the roads. It also seems to include residential roads.

Re: [Talk-GB] Environment Agency LIDAR datasets OGL licensed now available
Hi Chris Would it be possible to somehow use this data with the building outlines from OS OpenMap?. I know that data is somewhat simplified/generalised, but maybe combined together we could get an idea of how the simplified shapes from OS OpenData are terraced and even get their heights. I'm not talking about an import, but an imagery layer with both combined somehow. I've used OS and OSM data combined to produce free scenery for flight simulators http://world2xplane.com/2015/03/30/gb-pro-scenery/. (I've used OpenStreetMap for other countries for great effect, but the UK data lacks detail). Despite the simplified data, I've used various simple algorithms and rules to try and terrace the buildings automatically (It doesn't need to be 100% accurate for the flight-sim), and the results have given realistic looking UK towns and cities. For my next version of the scenery, I'm going to use this data to also get the correct building heights (my subtracting the height from the land mesh underneath). Perhaps this effort could be useful for OSM in some way.

Re: [Talk-GB] Restoring a usable map service!
I much prefer that style in your screengrab. It clearly shows what is or isn't a motorway and I think it's almost universally accepted (In Europe at least), that motorways are shown in blue. The current problem I see with the new default style is that it's very very difficult to now plan routes on a zoomed out map. I can't clearly see, for example, what is or isn't a motorway around Birmingham. Although the new theme looks nice, it is much less practical than the old one On 1 November 2015 at 11:02, Lester Caine wrote: > On 31/10/15 21:51, Frederik Ramm wrote: >> As for the remainder of your posting, about a "single base" and how all >> this is somehow related to a few colours changing on the osm.org map, I >> think you lost me there. > > Answered the colour problem in the thread on New Map Style. > > The problem with setting up a tile server is the GENERATION of the tiles > and how that can be modified to provide the other element I've been > banging on about.
