Pink Duck, look at the bottom right corner of the map : "(c)CCBYSA 2010 OpenStreetMap.org contributors"

Type of road provides a reasonable default in most cases, so I guess that the focus of explicit speed limits should be where unusual ones apply.

I traced a few roads and artefacts in Benghazi and Tripoli in the last few days. There is indeed lots of high resolution imagery that begs for armchair mappers !

Where is the "report spam" button ?

@Blackadder - For the local technical details of digging trenches to lay fiber, precisely surveyed plans are indeed required and OpenStreetMap cannot compete - we hand Autocad files to the digging crews.

But for higher level planning, deployment and management of the network, OpenStreetMap is totally sufficient - the proprietary map background I have seen in current use are worse than OpenStreetMap and their only value is that they do provide more even coverage in rural areas where OpenStreetMap still lacks.

A large French operator I work for officially uses WMS servers with proprietary data they license for internal use. The WMS background in the GIS software used there can be customized and I have also spotted users with Bing Maps backgrounds - but that is of course not official.

I bounced around the idea of using OpenStreetMap directly and got people quite impressed at the map, but the very idea that it is potentially incomplete and not an "official" source for which they can point fingers at a culprit when problems arise is putting them off - even though no one is deluded enough to think that having a culprit at hand will actually do anything.

I'll try again - I believe that packaged offerings from a reputed vendor such as Maquest or Cloudmade could make acceptance much more likely. At the scale of a large ISP, the cost is not the most important variable and no one has ever been fired from buying from the Institut Geographique National...

Looks much clearer - I like the focus it gives to the important pages. I would drop the shop link too.

Intéressante application du concept. Je serais curieux d'en savoir plus sur les outils que tu as utilisé. As-tu publié ces travaux ailleurs ?

La densité est impressionnante !

Je découvre du même coup l'existence de la reconnaissance de forme... Ca ouvre des perspectives...

Would waychain checking work for motorways in other countries ?

I guess that you already went through the basic instruction material available on this site. If you have questions, please write to the mailing list at [email protected] where you'll find fellow mappers eager to help. You can subscribe at http://lists.openstreetmap.org/listinfo/talk

Oups... Sorry for the duplicate...

By the way, that was found via OpenGeoData - http://opengeodata.org/nice-blog-post-by-someone-getting-started-wit

The "bot" account is a normal account - it just lets you isolate those bulk entries from your personal contributions.

Getting GPS logs from large fleets is a wonderful opportunity - I'm thinking about how to evangelize them about it...

Yes, features must represent the current reality.

Here is how I would tag that one :

highway=unclassified
surface=dirt
motorcar=no
lanes=1

I was going to say "awesome"... And then I found that Adam did it already !

I read about other initiatives such as loaning cheap GPS receivers to bus drivers. Sounds like fleets managers are people we should be talking to, to harvest GPS tracks at a large scale.

I have noticed that in many places, in countries in which Google does not have significant commercial interest, even many villages have part of their street grid mapped. But looking a little closer, this is a partial mapping of a seemingly random subset of the grid, none of those streets have names and the precision is horrendous. To me, this looks like what some grid recognition automaton would produce if configured to only trace the streets it detects with a certainty above a certain threshold. I mentioned that idea a while ago on OSM-talk (http://www.mail-archive.com/[email protected]/msg23852.html) but it did not get much echo. But I cannot believe that human mappers would produce such bad maps.

I like the very clear schematic diagrams. But isn't there a way to distinguish between L1a and L1b ?

@Ævar - I admit I let my enthusiasm get the better of my objectivity. From a rational point of view, you are right. But maybe some exuberance in expressing feelings is a way to attract attention - which then is more receptive to the more rational argument.

Nevertheless, I object that users of Map Maker know exactly what they sign up for : many users do not understand how licensing is key to the whole system. Making noise about it is a start - it may merely be a way to wake them up, but it takes a fully awoken user to start considering things rationally.

Your announcement made me discover TopOSM and I'm in awe of its beauty. With the CORINE land cover imports going on in Europe, it is going to be magnificent there !
