Hello, Congratulations for your first edit! Your ski trail will display on specialized maps, like here: http://www.opensnowmap.org/index.html?zoom=16&lat=60.32423&lon=8.53598 Even if I’m a cross-country skier myself, I have to acknowledge that ski pistes are not of particular importance for the vast majority of people, hence for particular topics like ski or sea navigation, OSM ecosystem will provide another map that fit your needs!

Why the pre-processing? Is ORDER BY “ele” not sufficient?

All in all, underground rivers are not that common. Looking at aerial imagery, in most cases you should be able to spot a bridge or a ford, isn’t it ? In that case, split the road around the river and add bridge=yes, or ford=yes.

The base versionning tool is Git, Github is a web platform to it, Framagit is another.

Ben c’est une très bonne idée ! Une version simplement Web, ce serait possible, tu penses ?

En fait, c’est un browser avec des cartes en bookmarks? C’est malin et pratique, bonne idée !

I would be reluctant to add any access=* restriction if there is no obvious restriction. A simple highway=track make perfect sense without other information. Yves

Your comparison uses a simplified coastline from OSM!!! :-)

The shorter driveway on the map is most certainly one a mapper bother to map. It’s up to every contributor, I guess.

Create an account and move a few nodes of the river in its right place, OpenStreetMap is done exactly for this :)

Maybe you can get data from http://openstreetmapdata.com/data and play with Qgis? Yves

It’s not like nothing happens, your concerns are duly noted here: https://github.com/yvecai/mapnik-opensnowmap.org/issues

Plus, there is something new here, and you can maybe help in proposing some lines styles if you are familiar enough with Inkscape : https://github.com/yvecai/mapnik-opensnowmap.org/issues/19

The DWG as an entity apply policies endorsed by the community or the Osmf. You are welcome to discuss these policies, but personal attacks doesn’t help in any way. DWG members have my deep consideration for their work.

Hi Tractor, Apart for piste:abandoned, good suggestions!

Piste:abandoned is not rendered because there is no more piste there, and even if I can understand nostalgia, it’s not openhistoricalsnowmap.org, I hope you’ll understand.

1) Improve contrast for XC trails against wood/forest and water Good point A bit of background: the default color (when there is no color=* tag in a relation) is closed to the swiss color in my area. But I think I could decrease the saturation of forest, for instance. If there is a default sign color, it could be mapped on relations. I think that’s doable in my area. 2) piste:grooming scooter and backcountry, fair point. I’m not used to those in my area. What do you propose ? 5) ice_skating: it’s a bug I need to correct 6) ski=yes, but how? It’s defined as ‘you have the right to ski here’, like an access permission. I don’t really know something useful mapped as this. To my mind, it’s ski=no that would be interesting to render. But I’ll need some more explanation on the meaning here, because although it’s commonly used (https://taginfo.openstreetmap.org/keys/ski#values) I have very little clue of what it’s really about. Maybe it’s worth to discuss it here: https://wiki.openstreetmap.org/wiki/Talk:Key:ski

3) Relation and grooming: It’s tough. Relations are rendered on top of ways in Opensnowmap. My main use case for relation is to provide feedback to the color=* tag. Look in France for instance, where relation with a color tag are manually offset to be displayed side by side. I tried once to erase a dashed line on top of them but it was quite ugly.

For 1, 2 and 3, could you make some mock-ups on what it would look like in your area? I don’t guarantee your suggestions will be taken as is, but this could help me to come with solutions. You can open issues here if you want: https://github.com/yvecai/mapnik-opensnowmap.org/issues

Bonjour Sylvia, Pour ce type d’aide, alors mieux vaut passer par help.openstreetmap.org, même en français, les réponses sont rapides. Merci d’y préciser le type de carte, et un lien si possible car là, il est difficile de vous aider sans en savoir plus. Yves

I’m so happy to live in an area very well mapped where I can go for a hike under the trees to correct paths mistakenly mapped by a fellow human mapper. Where is the added value in computers mapping from aerial imagery??

If it’s boring you to trace, then leave it out of OSM, add what you like to add instead.

Really Impressive work !

About these “cornet tails”, what about air traffic lanes ?

Yves

What is not completely open-source in OSV?

Merci Virgile, La dernière fois qu’on s’est dit ‘on part en vacance en train et en bus’, on a fini par prendre la voiture faute de trouver des bus. Peut-être quil y’en avait vraiment pas, mais j’espère que la prochaine fois on pourra compter sur OSM.
