[OSM-talk] finding overlapping buildings

[Mike Thompson]

https://github.com/MikeTho16/JOSM-Scripts
SelectDuplicateBuildings.js

To Run:
* Install JOSM's Scripting Plugin
* Place above file in a convenient location on your system
* Click "Scripting" (on top menu bar)
* Click "Run"
* Click "..." button and select this file.
* Click "Run"

Selects duplicate, or near duplicate, area buildings in JOSM's active data
layer. A "near duplicate" is a building whose bounding box overlaps another
building's bounding box by more than 50% (I couldn't get a pure area
compare to work).  Only the first building encountered of an overlapping
pair is selected. The selected buildings are added to the current selection.
