freebeer (2017-04-26 20:47:34+00:00): To followup to meself...
I chose to not adjust anything, as I saw the net distance is some 69 metres, while OSM.de seems to first want to add pitch markings from 80 (or 90?)m.  It would not surprise me if there is a sub-regulation size pitch in use at elementary schools like here, but not being familiar with the custom, I will keep my hands off.
I spent some time in the area and ended up adding some basketball and tennis pitches, with interesting marking rendering results.  In one park, a ways west, I saw a normal and smaller-sized basketball pitch, and only mapped the normal as I cannot authoritatively identify the smaller as perhaps a different sport.  But like with another area I mapped, there I fake-mapped a smaller pitch to get osm.fr to render markings, and once is enough...
It is interesting how the tennis pitches at Trenton Central High School (west) are rendered by osm.fr and osm.de, the latter getting nearly all of them way wrong.  I'm not sure of the reason for this or other observed differences, so time for me to compare the codes.
Anyway, I also wanted to note that in the 2015 aerial imagery available from the New Jersey Department of Information Technology as both infrared and visible imagery, when it finally appears (at least for me), has the pitch markings actually visible in a way that could be used to reposition the pitch, showing as dark lines.  I don't see these marks for the pitch to the northeast that itself is even smaller at some 43m between nets...
I do agree that the additional landuse tagging beyond the pitch leisure tag is a problem, with every renderer showing or failing to show.  But as I only mapped my first pitches a few days ago, and after a lot of false starts, I am but a beginner and in no way an expert.
Sorry for the interruption/annoyance.

Dalkvist (2017-04-14 07:56:28+00:00): Srividya while we appreciate the good work you’all over at mapbox do for OSM please don’t revert all the changes a new user makes unless you are 100% certain that it is vandalism. This user just looks like they need some guidance and we are several people in the Swedish community that keeps an eye on new users.
srividya_c (2017-04-14 09:15:05+00:00): Hi Dalkvist,

Thanks for keeping eye on new users. The edits in this changeset had incorrect buildings and ways which was the main reason for my revert. Will point to documentation in changeset comments for new users if I come across similar edits in future. 

Thank again
Srividya
Dalkvist (2017-04-14 09:39:50+00:00): Well at more recent imagery[1] there looks like there are new buildings and the names were common outbuilding types. They only needed to be changed to the correct subtag, straighten and removed the name. Same with the road it was named driveway in Swedish and just needed to be changed to service.

But this feels like a larger discussion about what to do with low quality edits from new users, I don’t think it is in the best interest of OSM to just delete them, if that had happen to me I’ll been pretty disheartened and less likely to contribute anything more.

Is https://github.com/mapbox/mapping/issues a better place to raise this issue?

Strange, I did not do things completely by hand but used copying, so I am surprised.

Can you give an example? With that I can have a better look and likely check if I made that error more often.

Thanks.
emvee (2017-09-15 20:55:32+00:00): I did a OverPass query for relations with highway=pedestrian and no area=yes and added area=yes to all these, so I think the problem is fixed.

Thanks for letting me know!
GerdP (2017-09-16 05:50:00+00:00): Sorry, seems I forgot to add a link to the object that lead me to this CS :-(
Not sure if that is better. On a single, closed way the tag area:highway is used to map the area covered by the road itself, while highway=pedestrian +  area=yes says that the area within the way is usable for pedestrians. 
You may still find obstacles like an amenity=fountain inside it.
I tried to find the problem relation again but failed :-(
I think I searched for members of MP-relations with a highway tag which don't have a highway tag.
GerdP (2017-09-16 06:04:30+00:00): Think it was this one:
https://www.openstreetmap.org/relation/5673340
emvee (2017-09-16 06:59:15+00:00): Aha, thanks, the original way object (https://www.openstreetmap.org/way/380740812/history) had area:highway=service and now the relation has highway=service.

To find relations with "highway=*" and no area tag, use in JOSM "Download from Overpass API" and past into it:

[out:xml][timeout:60][bbox:{{bbox}}];
(
  relation["highway"][!area];
);
(._;>;);
out meta;

Select an (somewhat larger) area and download.

I did so and see quite some highway=footway that were area:highway=footway in the past. For that I do not understand why not highway=pedestrian + area=yes is used. 

I did not know "area:highway" but just read https://wiki.openstreetmap.org/wiki/Proposed_features/area:highway and https://wiki.openstreetmap.org/wiki/Talk:Proposed_features/area:highway. It is not too clear to my opinion, but I read "Considering that the areas would be mapped in addition to the ways" and that give me some guidelines, it is additional for visual purpose.

I am still wondering how the error happened, I most often used Tools->Update multipolygon (Alt-z) and just tried that once more and I see it does the right thing.
GerdP (2017-09-16 07:06:52+00:00): Yes, area:highway is used by special renderers. 
Looking again at it I think in case of https://www.openstreetmap.org/relation/5673340
you really improved the mapping. 
Sorry for the noise. I found other cases that IMHO did not improve the data, see https://www.openstreetmap.org/changeset/47783387
emvee (2017-09-16 07:49:52+00:00): No problem for the "noise" ;-)

For the particular case of https://www.openstreetmap.org/relation/5673340 I see how area:highway=area could make sense but before going that way, it would make sense to adds ways indicating how to access this service area and how to drive over it.

sebastic seems to have changed area:highway=* into highway=* deliberately, I think I did not do that. For the particular case of https://www.openstreetmap.org/relation/5359290 I think area:highway is more appropriate as there is already an other highway ("for routing") and this is just "additional for visual purpose"
GerdP (2017-09-16 08:00:42+00:00): Yes, and another potential problem here is that one may confuse area:highway=service with highway=services + area=yes as in https://wiki.openstreetmap.org/wiki/Tag:highway=services
