Each conversion has errors

That is something that should be easy to solve

And I would be okay with one unit per country. But as stated in the post, it is not that simple and makes automated and human consuming too complex IMO.

Is mapping really the process down to the database? I doubt that. Mapping means modeling the real situation with the tools we have. The tools will evolve and so should the mapping process making the database more concise and the mapping process less complex.

but is an OSM maxwight or others like road-width ever used in calculations?

Yes, sure. E.g. if you want to know if a truck of width X fits through it or not.

The best way would be to change the earth use of units to SI ;-)

It is important to keep local things as they are and make the mapping as convenient for the mapper as possible. But again: why would the database need this complexity if we can handle it in the editor?

The OSM project grows, tools get better and so we should make it possible to freeze certain definitions of tags and check them in the most popular editors as it is currently already done.

Interesting! So you check only the connectivity or also the distance changes over time like @flohoff is doing? If the first, then you should be able to easily do this with (a local) GraphHopper, it is called subnetwork calculation and will be much faster and precise with regards to the precise node set. Or just use normal route calculation.

@flohoff let me know if you need support when testing this with graphhopper :)

BTW: GraphHopper is deterministic, even if it does stuff in parallel while import.

For routing we do the same in GraphHopper import as we only need the junctions and end points. But I doubt this makes or will reduce much of the data as the ways are not always this straight in real world. And even if you want to reduce this which difference via douglas-peucker is acceptable 1m, 0.1m or 0.0000m? Reducing the data if it is not 0.00000m difference will reduce the quality in certain cases.

This is just a displaying setting and a dynamic elevation visualization has other problems.

Das war kein Schnellschuss. Das hat ewig gedauert: https://github.com/openstreetmap/openstreetmap-website/pull/716

Aber warum? Weil fast nur Richard wirklich Zeit investierte (ich hatte auch keine). Wahrscheinlich wäre ersteinmal eine Lösung ala http://openstreetmap.de/karte.html besser gewesen.

Ich prangere das an.

Das bringt nicht so wirklich viel. Mitdiskutieren und implementieren schon.

Wir hoffen auch auf Leute die die Router wie: https://graphhopper.com/maps/

und natürlich die Daten für diese verbessern:

Es gibt von esri oder mapbox satellitendaten, von osm natürlich nicht ;)

Klickst Du hier ‘esri’ oben links: https://graphhopper.com/maps/ da gibts auch (outdoor) layer die höhendaten eingebunden haben.

This is what I’ve found from HOTOSM http://www.missingmaps.org/ where there is e.g. this. So the infrastructure is already there and even nice&useful :)

Yeah, also a nice idea! Someone should make a company out of these all so that I can use it ;)

I would have no problems to limit the work to local mappers. Also I would like to see that those local mappers involved somehow. Be it via financial support and direct involvement or as a protection wall for those paid contributions.

Yeah, but I have already too many side projects where I’ll be billionaire afterwards ;)

That is true but normally if you pay for something you look at it even more closely (?)

Yeah, I still think there is potential for a OSM specific site as you could put bounties on OSM notes, select an area and define specific tasks, select specific tags which should be improved or even just a kind of a commercial version of maproulette.

Still wondering why there isn’t one already :)

Yeah, interesting idea. Maybe bountysource or flattr :)

Sorry was just reading the wrong entry. Here is the root post: https://lists.openstreetmap.org/pipermail/osmf-talk/2013-November/002344.html

I mean more to hire several people like for taskrabbit but more for OSM explicitely

@davespod the motivation would be money in the cases I mentioned. I don’t understand the link you are referring to as they don’t discuss paid contribution IMO

Sorry, the road number after the comma was my fault. That is not part of the name that is just the ref: way/51109811

Thanks @Zverik and @d1g ! @d1g - which code is the one for the examples above (e.g. the first example)

What do you recommend to do about it? Leave them as it is or move them (manually) to official_name and provide shorter ‘normal’ street names for navigation and address search? Maybe I’ll also ask the user about this.

The official recommendation for name tags is:

The names should be restricted to the name of the item in question only and should not include categories, types, descriptions, addresses or notes. If something really doesn’t have a name, don’t add one to OpenStreetMap. Any additional information should be included in separate tags (see, e.g., aforementioned links) to identify its meaning.
