Highways that are under construction are impassable for motor vehicles, but they are often usable

I consider that a very bad advise for OSM consumers.

I recently read somewhere that an OSM contributor is waiting for an OSM fork

It’d be interesting to know more about that - what did they actually say?

All I can say, there are people not waiting for a fork, but restraining from contributing altogether, e.g. OSM Carto issue 1500 has one single such PoV. May not be an issue for OSM to get MLT (more like that or mutton-lettuce-tomato) There will always be others to fill the gap.

Meines Wissens wird das bei der Baubewilligung geprüft und das nicht erst seit gestern. Abweichungen von geltenden Richtlinien (Entfernung, Literleistung, Druck usw.) sind in Absprache mit den lokalen Feuerwehren eventuell zulässig. In welchem Ausmaß weiß ich aber nicht. Am Ende gilt was im Bescheid steht.

Aber ja, es gibt ganz sicher eine Menge in openstreetmap nicht erfasste Hydranten (Ober- wie Unterflur), hab auch schon ein paar erfasst, aber nicht jetzt wirklich gezielt :)

Those assumptions might work well in Europe

Speaking from there, NO, they may fail here just the same. Most often, from what I observe, because there is no “stream” there on site, but only in the data.

On the other hand, such cases do exist: When there is no water in the “stream”, there is no ford – When there is water in the stream, it is not advisable to “ford” it! (Shouldn’t that be tagged ford=no then?)

Funnily, this conundrum results in: Consumers rendering fords very prominently might actually provide useful information: In case of bad weather, this way may not be traversable. At least, when the stream also shows as “intermittent”, that coincidence might be a way of instructing map/app users about possible dangers/inconveniences when planning a trip.

Unfortunately, editor suggestions lack local knowledge that might help decide. Even more unfortunately, people following editor suggestions obviously lack that local knowledge just the same.

Funny that you mention this. During writing of my diary entry, I noticed that there is not many https://taginfo.openstreetmap.org/tags/amenity=shop! When following the path example, the - to some at least - more interesting stuff than that there is a shop there - namely what it has on sale - then would be tagged in attributes like bot_stationary=yes and computer_hardware=yes. When I filter here https://taginfo.openstreetmap.org/keys/shop#values for semicolon “;” I see that 1:n relations are not popular there neither, apart from convenience;gas.

I consciously worded the post as a fairy-tale. Therefore I did not see a need to explicitly mention, that this likely not the way events actually unfolded. Just now happened over https://community.openstreetmap.org/t/rfc-deprecating-highway-road-in-favor-of-highway-unknown/118864/47 – Perhaps it all is about for cars or not for cars? Paths conveniently surveyed from within a car osm.wiki/File:Path-footyes.jpg nevertheless.

Heute in der Zeitung, pardon dem Fernsehen:

Forststraßen länger als Straßennetz

Österreichs Forststraßen übertreffen mit einer Länge von 218.000 Kilometern das Straßennetz bei Weitem, das gerade einmal auf 127.000 Kilometer kommt.

In July I did revert a bunch of really sloppy edits by a power mapper. He returned under a different nick and reverted my revert, saying I have to be more careful, there is good stuff also. In his revert, he again removed houses that obviously were not on his outdated aerial, so much for lacking care.

Meanwhile a DWG member reverted this and lots of other changesets of this picky power mapper. I guess, for the hdyc algorithm these are two separate reverts? I learned to live with 1.3% of all the changes in my whole career being reverted ;) I just hope this number will not get used against me.

Does that happen more often, enough to skew statistics?

The missing GPS data - only your own single capture eg. - use of strava heatmap can help a lot! Coverage is really good. More info in this community forum topic https://community.openstreetmap.org/t/new-strava-heatmap-extension-for-id/100544 - Then there are also the OSM own tracks, but there are not so many.

It would be much easier today, if hedgerows were mapped as barrier=hedgerow on a line, and thick hedges as barrier=hedge on a closed way meant to represent an area. Yet, that ship has sailed.

Nowadays, new tagging has a steep barrier to entry. The OSM-Carto issue on that is just bagatelle.

Overpass length() seems fairly accurate. The two courts linked above output 110.079;110.175:

[out:csv(number,length)];
( way(id:788871677,1029667455); );
make stat https://wiki.openstreetmap.org/wiki/Tag:number=count(ways),length=set(length());
out;

This slightly differs from what JOSM gives, but negligible for our purposes. Curiously, JOSM disregards projection when copy/pasting one to the place of the other - the difference is staggering.

Around here way/678206560 maps 9 courts as a single pitch and the mapper commented the changeset “micromapping sports” ;)

PS: Beware when counting: Doubling length of the outline makes the area fit 3+ courts. 370m circumference, only three times 110, fits 9 courts and the space between.

The biggest promise in mapping sidewalks as separate ways is, that businesses can make a so-called pedestrian router that is just a copy of their car router, but operates on a different grid. The ones to gain the most are people in mobility scooters, a car-like vehicle. The visually impaired here do not use any navigation aids, it so, they use google maps. They know about blind-square. In my opinion, the blind should be the ones to profit the most from a true pedestrian router. That though requires more than just a separately mapped grid - one for pedestrian, one for vehicles. Unfortunately, there is not much money to be made from them.

Noch eine Zahl zu den Forstwegen, für die https://wiki.openstreetmap.org/wiki/Tag:bicycle:conditional=Yes @ (Apr - Oct) gilt - durchs Hintertürl gesehen sind es einmal sicher so um die Drei, Vier- von den 18 Tausend km, wenn man alle in Openstreetmap erfassten MTB-Routen darauf hin anschaut, wo sie über tracks führen - siehe https://overpass-turbo.eu/s/1qHW gibt aktuell 3030 aus - und das mapping ist nicht ganz vollständig
