[OSM-talk] Another OSM use without attribution (unusual rendering)
In today's Metro free tabloid newspaper in London, there's sponsored article (promoting Expedia), which extolls the virtues of the Shoreditch area of London. Fair enough, they want a map, so they've taken Openstreetmap data, tweaked the rendering to abbreviate street names (Old Street becomes Old St), tweaked the styling, but it looks very much like Mapnik, and an old copy of Openstreetmap data, based on the building outlines (I know, I mapped some of the buildings there). Oh, and they've not attributed Openstreetmap as the map data source. http://www.zymurgy.org/~simon/metro_osm_no_attribution.jpg vs http://www.openstreetmap.org/?lat=51.52694lon=-0.08141zoom=17layers=M Print copy is Metro newspaper, page 33, Monday 22 July 2013. -- Simon Hewison ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Re: [OSM-talk] how are runways related to an airport/aerodrome
Madhav Vodnala wrote: This is a good idea. Is ICAO code same as the airport code as identified by US DOT?. ICAO codes are international, and cover all licenced airfields worldwide. They are four letters long. Those DOT codes seem to be the same three letter codes as the IATA codes (which passengers and travel agents book tickets with), and in the USA, you can easily convert IATA to ICAO codes by prefixing with the letter K, so LAX becomes KLAX. Pilots and Air Traffic Controllers use ICAO codes. In the rest of the world, it's not so easy, so EGLL is LHR = London Heathrow. (E tends to denote Europe, so EG = Europe, Great Britain). Someone once told me there was some reasoning behind the name of the ICAO codes, but it escaped me, and they couldn't name it at the time. France is LF (La France), Germany is ED (Europa Deutschland). eg .

[OSM-talk] different results returned via various APIs
I know that Potlatch uses a different API than the main XML based API.. but I've noticed something really quite weird. http://www.openstreetmap.org/?lat=51.85278lon=-4.89509zoom=15layers=B000FTF If you look at the railway line heading to the southwest from Clarbeston Road, in Potlatch it's a nice curve that follows the NPE maps nicely, but in JOSM - and what gets rendered via mapnik, ti...@home and so on is containing far less nodes. The way in question is 33116814. JOSM thinks it's only 4 nodes, yet if if use the data overlay, and view the data that way, it's a good number of nodes in it. It looks like somehow most of the nodes used are in someway invalid, and only potlatch's AMF api is able to return them from the database. -- Simon Hewison ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Iván Sánchez Ortega wrote: I don't think OSM is the place for statistics... it has been said over and over map what is on the ground. But what we should be able to do is use the OSM data to easily correlate with available statistical sources, which means things like official boundaries and so on in the OSM dataset, so if someone said that statistically, the London Borough of Barnet has less car crime than Moss Side in Manchester, then it should be able to plot those areas on a map. Whether anyone would want to build such overlays into applications like a vehicle navigation system Find the nearest on-street free parking where I'll be able to come back and still likely find all my vehicle intact.. is another matter. Not that any of this matters. Crime maps and statistics are always retrospective. Any crime figures for my street show a very low crime level, but that didn't stop my house being burgled and my car vandalised in the space of a weekend. If we can come up with a method of providing a reliable crime forecast and put it on a map, you've got a very valuable product.

Re: [OSM-talk] New Mapnik Style

Seems like lots of changes have been applied, which has considerably changed the look of the Mapnik Layer. I wondered if there is a summary of changes explained somewhere, and even maybe some of the motivations for those changes? I've spotted that boundaries that used to be rendered when they followed streams, nowadays, Mapnik is only rendering the stream in such cases.

Re: [OSM-talk] ref in roundabouts
On Tue, 2008-10-07 at 11:45 +0200, Celso González wrote: Two options here: -ref is the one or ones that are used in the highway -ref is not needed at all I'd suggest that ref is not needed at all, unless the roundabout itself has one that is unique to itself. Quite often roundabouts are named. I guess that some of them may have some official reference number as well. It shouldn't normally have either name, or reference of any of the joining ways. Any route describing software should pick up on junction=roundabout, and work out which exit of the roundabout to describe the manoeuvre as, and ideally what the signposts might say on that exit. Of course, counting exits needs to count permitted exits - quite often some roundabouts have oneway roads joining them, if they're not leading away from the roundabout, you don't count them. Some examples of roundabouts that might cause problems: The Handy Cross Interchange, High Wycombe: http://www.openstreetmap.org/?lat=51.61291lon=-0.76999zoom=16layers=B000FTF A4 Wellington Street/A412 junction in Slough: Note: This is not grade-separated.

The ways across the top of the roundabout are indeed part of the A4. http://www.openstreetmap.org/?lat=51.50815lon=-0.581066zoom=18layers=B000FTF Then of course, there's got to be the obligatory roundabout with oneway=false. This one is the Magic Roundabout at Hemel Hempstead, but there are others.

Re: [OSM-talk] Australia has Google Street View!
wer-ist-roger wrote: Hello Stefan, Interesting question. Are we allowed to use street view images for mapping (filling in street names, amenities, house numbers) or do we need explicit permission like for aerial images? If your not sure about the legal aspect DON'T use it! And from my point of few it is not allowed to use Googles photos. And if Google were partly evil (though they claim not to be), they might alter their image obfuscating code (to blur people's faces etc) to identify street name signs, and transpose one street sign onto another, and create an easter egg in their creative work. Since they already claim to have the ability to blur vehicle registration plates, and people's faces, if this needs even a little human intervention to achieve, then it could be counted as a creative work, and subject to not only database right (the geolocation / rectification work of the images), and copyright on the eventual image that has has processing done on it. So. I wouldn't trust it, and I wouldn't use it, unless Google can explicitly say we're allowed to do it, and if Google can explicitly say that they're not doctoring the bits of the images that we're interested in - like street names, building names and so on) -- SImon Hewison ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Do you (or anyone else) know what is actually on the ground, as I am sure that having it tagged as motorway is wrong?! That would have been me, who mapped it, in person. I rode my bike along it.. which is maybe illegal, but maybe not. It's really there on the ground, and really is a slip-road, just that either end has crash barriers to prevent people from using it. The hedges either side are overgrown, but is apparently still being maintained sufficiently to be put into place as an exit at short notice should the current real J2 southbound slip road be out of action for a prolonged period. There's even street lights. Microsoft's Bird's Eye view on maps.live.com shoes a fairly accurate representation of what's on the ground. I tagged it as highway=motorway_link; use_status=disused (which was the preferred method of tagging such things at the time), and made sure that neither end are connected - because they are not really accessible from the roads at either end. -- Simon Hewison ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk

Far less friction than a tyre-wall friction dynamo, it doesn't generate that much power, but it's enough to run flashing LEDs. It does just make a 'tick tick tick tick' sound as you move, and it's quite satisfying hearing the beats per minute of the ticking go up as you go faster.
