[HOT] Buildings in DR Congo

Sun Jun 10 18:06:22 UTC 2018

Some nice person wrote me a small JOSM script.

https://www.jatws.org/johnw/SelectDuplicateBuildings.zip

You need runscript plugin for JOSM and the todo list.

The way I work is to use an offline version of the area and find the
duplicates.  Then I take a village at a time that contains duplicates and
redownload the small area to have a fresh version since its deleting things
and you don't want two deletions of the building.  Run the script and use
to todo list to check each one.  Repeat for another area.

I agree about the 500 duplicate figure its just tedious doing them one at a
time and if this can be avoided it gives us more amping resources for
somewhere else.  I have tagged more than a hundred untagged buildings with
a HOT tag line in the area as well.
