[OSM-talk] finding overlapping buildings

[john whelan]

>
in JOSM
<ctrl-f>
Search Syntax = Mapcss selector (lower left of search dialog)

enter the following for the search string:
area:closed:areaStyle[building] ⧉ area:closed:areaStyle[building]

(The character ⧉ is unicode 29c9)

This works but gives the same results as select buildings then validate
with crossing ways.  I'm not after ever building that overlaps by a small
amount its the duplicates if I can get them.
Thanks John
