No !!! Not my house !!! :)

You seem to have done a good bit of editing already, can you state your question more precisely ? To download the trace data in JOSM, just tick the "raw gps data" box when downloading an area to edit. And for questions like this, http://help.openstreetmap.org/ is better than the diary. The wiki would probably have your answer too.

OSM is usualy ahead (at least in popular areas) for pedestrians and recent modifications. In my city there are even two spots where OSM is ahead of the national mapping authority.

Sometimes it happens at a more impressive scale though : see http://tools.geofabrik.de/mc/?mt0=mapnik&mt1=googlemap&lon=-7.13802&lat=52.61326&zoom=12 for a strech of motorway that has been opened in september 2010, but so far only OSM and the national mapping agency are aware of it (just checked google, bing, ovi(navteq)). The motorway appeared on OSM the very next day after the inauguration.

Or when drivers don't notice the one-way sign or any other sign that contradicts the GPS. All GPS manuals have a "dont trust the GPS as the only source of information" disclaimer for a reason. It's harsh, but dying after driving off the visible road in an omniously-named desert deserves a Darwin Award.

That said, we of course must strive to make the map correct. tracktype, smoothness and surface sound like the main contenders to me in this case. Didn't know about 4wd, but it looks more like an Australia-specific legal designation, not a generic tag.

Amen to that. I wish more people who do not like the ODBL or CT (a tricky question, so it's understandable that views differ) would reallize that accepting the ODBL before stoping contributions (or contributing to a fork) is a possible compromize. Thanks for not making your past contributions a net loss for osm.org, and good luck with the fork.

In that case... Don't map it ? Unless you know for sure (official documents) that it's an area under construction (with a proper ETA), then you could map it as such, so that it can be easily tagged as highway=residential (or whatever) once it's constructed. Otherwise this is like the various forms of "disused" tags : not useful and more likely to cause problems than anything else.

Wenn den weg noch nicht existiert, kannst du dein .gpx direkt benutzen. Wenn es bereit existiert solltest du mehr vorsichtig sein.

Du kanst auch das "average waypoint" menu benutzen, um ein genauerer waypoint zu speichern. Am besten ist es, wenn du mehrere stunden später am gleichem ort kommst, und das "average waipoint" wieder benutzt. Probier ein waypoint zu speichern, der auf satelliten-photos einfach erkennbar ist, dann kannst du es als "survey_point" im OSM eintragen.

PS: Entshuldigung, mein Deutsch is nicht so gut.

Oui le tracé des océans est fait beaucoup moins fréquement, ça peut surprendre. Le plus drole c'est quand l'administrative_boundary a bien bougé sur le rendu, mais la limite terre/mer pas encore (alors que c'est le même way qui définit les deux).

Even appart from copyright issues, street names in googlemap are wrong more often than not for anything but the main roads. I'm sure it depends on the region of the world, but in my city it's ridiculous. And the national mapping agency is better, but not free from errors either (not even talking about copyright-gotcha intentional mistakes). So go out to check the facts; part of the fun is visiting the area :)

Sympas. Les remontées via le forum sont efficaces ? La communauté villavelo prédate le travail sur la carte OSM ?

Il y a un énorme potentiel de crowdsourcing pour OSM par les "non-techniciens", mais il est difficile à utiliser. Le système de mapquest est celui qui je pense a le plus de chances de réussir globalement, mais les initiatives plus spécifiques comme celle-ci ont leur place aussi je pense.

Bon courage ! Et pensez à élargir votre carte à d'autres villes si ça marche bien :)

"Proper" spamers will quickly learn to do a quick edit of the map before posting on the diary. Some might even put spam-like data in the map (imagine if nominatim turned up a viagra add...). I really dont want to tempt spamers anywhere near the map.

I like this use of a namespace, it's fexible and elegant. Although I'm not very keen on mapping disused features in the first place, this method at least doesn't screw up simple users.

You can also say what feature of the object has become disused : maybe the pub still exists but its website hasn't been updated in 15 years. Maybe you're mapping an antena (man_made=tower) that isn't used for communications anymore. In that context, I think that the plain "disused=yes" tag should not be used at all: only put various keys in the "disused:" namespace but do not add a "disused" tag.

Wonder where you get the "couple of centimeters" metric from. I've had a look at all this and, while a combined system will bring better accuracy, it's not going to be sub-meter yet. Probably have to wait for a chip that does GPS+GLONASS+GALILEO :)

Gnash has had trouble with potlach since potlach got rewriten using actionscrip 3: http://www.gnashdev.org/?q=node/72
I dont follow gnash dev very closely, but I do not think they've made enough catchup work yet :(

Try a non-flash editor instead, like JOSM or meerkartor.

The "planet file" is essentially a backup of the data before CC-licensed data (or edits based on prior cc-licensed data) gets deleted from the main OSM project. It'll certainly be in the usual OSM format, available for anybody to pickup and use to create his own OSM website (as is already possible currently : both data and code have always been avaiable for any determined person to setup a full OSM stack).

But while it's "easy" to setup a mirror OSM website with the old data (you can be sure that some people will, at least out of historical interest), making further edits to it and forking the community would be both difficult (most people are happy with the odbl) and damaging (splitting the efforts instead of working together).

Nobody likes having to change the license, it's a painfull process. But it had to be done, simply because CC licenses are technically not adapted to a database of facts like OSM. CC has been created with artistic work in mind, and to a layer that's an important difference. The fact is that CC-BY-SA could not provide the expected protection in many countries, so another license was needed.

The ODBL may be new and painfull to read (like every license including CC-BY-SA), but its spirit is pretty much the same as the old license. I think that most people who haven't clicked "I agree" are just annoyed at the change (rightfully) and reacted out of spite and/or misunderstanding (wrongfully).

If you want your contributions to be PD, there's a checkbox to do that once you agree the ODBL, although I think it currently is just a statement of intent, not a legaly-binding declaration. If you actually dont like some effect of the ODBL (nevermind the wording), you can still click "I agree" and never contribute again. You'll have saved the bulk of OSM users the bother of having to re-do your contributions under the ODBL license. Wether you agree or not, all data before the cut-off date will remain available in the CC-BY-SA licensed "planet file". And some day, hopefully, you will realize that the ODBL is not such a big deal, and carry on contributing maps for the Greater Good.

J'ai un 62s aussi et - contrairement à l'eTrex que j'avait avant - il se met en mode "clef usb" tout seul. Peut-être qu'il se met dans un mode différent par défaut chez toi parce que tu a installé un driver spécifique (et peu utile) ?

Je n'utilise pas de carte SD, il y a largement assez de place sur la mémoire interne.

N'oublie pas de régler le parametre "setup->routing->lock on road=off", sinon tes traces s'aligneront artificiellement à la carte chargée (ce qui pose en plus un problème de copyright si ce n'est pas une carte libre).

Va aussi faire un tour du coté de "setup->track_log->recording_interval" pour enregistrer plus de points.

Not quite sure what you're looking for.
* To get notified yourself, you can use http://matt.dev.openstreetmap.org/owl_viewer/ to watch for changes in your area.
* If you want to notify the owner of something that got added to the map, I can't imagine how that could be automated. Best is for the mapper to send an email to that person, if the email can be found. Actually, that email is a good opportunity to do some OSM evangelism :)

I think OSM is a product that is in most core ways supperior to GoogleMaps. The main (huge) drawback is the lack of satellite and street view and I don't see how that can be fixed, but the rest is either as good, better, or can be improved. One thing I'd love to see improved to GoogleMap's quality is "share your trip planning, with custom POIs and on an anonymous url" feature. Nominatim needs to get better, too.

The other thing we need to keep working on, my friends, is every-day pervasive PR :
* Wear OSM HVV or Tshirt when mapping
* Use a specialized app to look at the map on your desktop and phone: I use http://edu.kde.org/marble/ and got a lot of "Wow, what maps are you using ? They're fast !" comments
* Show off locations where OSM data is better than $CLOSED_MAP_DATA
* Mention open.mapquest.com and bing, since they're more likely to be known
* Mention all the specialized maps and use cases that $CLOSED_MAP_PROVIDER just won't provide/enable/permit
* Mention the army of contributors and how easy/fun it is to join in (do a demo !)
* etc...

Have fun mapping trails ! They're quite rewarding, since you're often working in an area with very few existing data; even maps from the national maping authority are sometimes not great for trekking. For added fun, you can add 3 hours of off-track walk to your day just to add 500m of OSM-worthy highway=path (like I did last weekend) :)

Can't see anything wrong with the trace you linked to. When mapping trails, the most important tags I think are track/path, tracktype, sac_scale, and trail_visibility. Any shrine or ruins are also usefull to map. Have fun !
