allow querying by object area/way length

[matkoniecz]

Usecase example: finding mistagging like https://www.openstreetmap.org/way/222795099#map=19/52.51666/13.41946&layers=N or excluding them in program processing OSM data (I wanted to add this functionality in StreetComplete).

I believe we already have an issue for this, so marking as duplicate of #237.

Not sure what you mean by area “length”. Care to elaborate?

[matkoniecz]

I thought about two cases: way is closed, filtering by area is available and second: way is not closed and length is available

[mmd-osm]

A closed way doesn’t necessarily imply an area in an Overpass sense, e.g. if there’s no name tag... there are dedicated rules for area creation.

[mmd-osm]

Future syntax for non-closed ways with a certain min length will look as follows:

way(if:!is_closed() && length() > 10);
out geom;

Check out the following example: http://overpass-turbo.eu/s/wGT

As there's really nothing left to do here, kindly request to close this issue. Thanks!

[matkoniecz]

Thanks! Is it feasible to allow filtering by size (area) of closed way - like buildings, lakes etc?

[mmd-osm]

I don't recall if Roland already implemented such a function for area sizes, will cross check.
