D'où l'expression "aller au charbon"

OS Street View Copyright Easter Egg about 1 month ago

Easter Egg and OpenData are not compatible.

It's not because you have accurate data that you have to upload all of them in OSM about 2 months ago

If you don't want to loose all your accurate surveyed points, they are still in version 1 of the way & nodes. Or another solution would be to upload your surveyed points as GPX files. These trace files are preserved in OSM and nobody will modify them.

Go home coastline data, you are drunk 2 months ago

What ! You have the power to remove waves from the coast !! You are stronger than Poseidon ^^

Infrastructure télécom 2 months ago

Une couche de quoi ? en rapport avec OSM ? avec la cartographie ? Tu devrais en dire plus et surtout, utiliser le forum ou la liste de diffusion pour augmenter les chances d'être lu et d'avoir plus de contacts

OrdnanceSurvey does like amateurs 2 months ago

It's a matter of principle. They cannot say in one side that making their maps require professionals (and budget) and cannot be done for free and in the other side, ask for free pictures (because the prize is a joke compared to reproduction rights and amateurs are set at the same level as pros). They ask to photographers what they refuse for cartographers...

nothing to do with OSM -> spam

New Telenav Mapping Project: Dual Carriageways 3 months ago

When I see your profile's image, mvexel's, I'm interested to know if your are the son of Chuck Norris.This striking resemblance, it's disturbing....

Voting is bullshit 3 months ago

We should not vote on new tagging schemes, we should support them - or not.

But this does not work as well. You create multiple and parallel solutions for the same problem, depending only on decision made by a few number of data consumers.

It's true that proposals are often accepted with a low number of votes and where the result is still unsatisfactory. We can all dream about a dictator or great engineer taking perfect decisions making everyone happy but this only exists in books, not in real live.

About the low number of votes, it's like in real democratic system. Only non-voters have to be blamed, not the one who expressed their opinion. But as I said several times in the past, the words "vote" and "approved" are incorrect. We should better say "opinion pole" and "best reply".

Vous noterez la présence sur la photo d'un gâteau qui vole. Bravo au photographe.

Changement du nom de 8 communes 4 months ago

Je ne mettrais pas place=village pour Vermondans. Ca serait possible si l'ancien village était isolé mais comme il fait partie d'une seule agglomération au sein de Pont-de-Roide, il serait plus logique de mettre "place=quarter" (il faut être sûr de l'emplacement)

The diversity-talk list 4 months ago

I just discover this list. It's even missing in the MailingList wiki page. I'm surprised by the answer of Alyssa here which tells me that we should never reply before taking time for a deep breath. Btw, who is the other moderator ? I also had a bad experience on the import list with a moderator that blocked me on the import list (if I remember correctly) several days for really nothing (or something that way maybe overinterpreted when you express yourself in a foreign language). I think we need a coach for our ML moderators or a moderator for moderators ;-)

How to improve OSM: kill the bureaucracy 5 months ago

As I said, it is to discuss about a proposal, not to store the proposal itself. It is not more and not less of what the wiki "Talk" page is doing. Excepted that you don't have the learn the wiki syntax.

How to improve OSM: kill the bureaucracy 5 months ago

I went through the arguments of this wiki-better-than-email but none of them is valid in our context. Our tagging mailing list is not providing "material of any substance". It's just discussions around what will go into the wiki page exactly like we have in the wiki "Talk" pages. The "signal to noise", "search" and "PD" are not relevant as well (use google tip "site:" if you like). Some people don't like mailing list because they simply don't have a correct email client supporting mailing lists.
They are counter arguments about the wiki. The main being that many people simply never used a wiki until they wanted to discuss about a tagging proposal. Don't forget that our audience is not limited to nerds.
I agree on one point : the process to adopt a tag can be heavy and slow. But you can bypass this process and simply use your owns. By doing this, you also take the risk that your tag is undocumented or badly documented and then unproperly used or interpreted by others. You also have to understand that tags are not just a wiki and a k/v in a database. When you create a tag, you also want that this tag is used by others and not only for rendering. Once a tag is adopted by data consumers, it is very hard to modify them (although not impossible, I did this for the tag emergency=aed in the past.

Sentinel-2 satellites imagery can be used for OSM 5 months ago

Launch is planned for april 2015 for the first satellite. About the attribution "contains Copernicus data (year of reception)”, perhaps a mention on the contributors specific attributions on the wiki would be enough.

Entered minor changes, JOSM appeared to hang 6 months ago

The main OSM server(s) has been planned for maintenance and quick downtime the 26th. See the announcement here :

Your josm upload issue is probably related.

New MapRoulette challenge: TIGER Mismatched Ways 6 months ago

One question from a non-US contributor: what is recommended if we find a TIGER imported road in OSM which seems to not exist at all on imagery like this one:

simply delete the way ? or change the tags to 'disused:' or 'razed' ?

Redundancy in Buildings 7 months ago

I think too the relation type=building is the problem. If the block is a single building, then create a multipolygon relation. If it is different buildings, then create a surrounding polygon for the tower (or keep the tower tags only on the tower polygon)

Détérioration très importante de la carte de l'île de la Réunion. 7 months ago

1/ C'est un parvis comme il en existe bcp, généralement piéton et cycle. Celui là est autour d'une église, mais ça peut être une place dallé piétone ou tout autres parvis du même genre. Je dois admetre que je me suis touours demandé comment taguer les trottoirs et ces choses du genre qui sont à la foi area et way.

Pour le parvis, c'est alors highway=pedestrian + area=yes + bicycle=yes

Pour les trottoirs, c'est plus délicat. Peu de gens descendent à ce niveau de détail pour l'instant. Et si on cartographie la surface du trottoir, il faut aussi le faire pour les zones de parquage voiture, les petits coins d'herbes ou de fleurs, etc. En fait, il existe des expériences très locales qui s'arrêtent très vite lorsque les contributeurs se rendent compte de l'ampleur de la tâche...
