I have tried the following in order to obtain all the pools of which length is > 10 meters.
/*

The original search was:
““swimming pool””
*/
[out:json][timeout:25];
// gather results
(
// query part for: ““swimming pool””
node"leisure"=“swimming_pool”;
way[“leisure”=“swimming_pool”](if: t[“length”]>25)({{bbox}});
relation"leisure"=“swimming_pool”;
);
// print results
out body;
;
out skel qt;
Out of maybe 500 existing pools known by OSM within the bbox, it highlights only 1, so something is wrong. I guess people do not enter length when creating a pool object.
If you want this type of information, I’d suggest requesting people consider adding it at the talk-gb mailing list. It’s usually known locally, so fellow contributors may be able to improve this aspect of the data quickly.
