Re: [talk-ph] OSM contributions - some basics for a newby

[Glen Scott]

Thanks Erwin, all noted.

I'm sure I'll have further questions on conventions or even basic editing
queries - is it best to ask here or via personal email, and if the latter,
who should I ask?

I've seen the PH conventions page, and finding it useful (e.g. tagging fish
farm pond "water") but one example where I'm not 100% clear would be the
pond dividers, where I see there are a few techniques in use, well at least
two (a) leaving some land between the ponds, and (b) making one large pond
and dividing it with lines tagged as embankments.  I see both in use; my
attempts so far have been to leave strips of land, though the embankment
line approach would be quicker.

Cheers

Glen

[talk-ph] Fwd: [OSM-talk] finding overlapping buildings

[Erwin Olario]

This could be useful for the Project NOAH cleanup task[0].

How's that going, anyway? Maning?

John, Pierre,

I made some improvements to the select duplicate buildings script. It now
uses a spatial index, which makes it a lot faster on large datasets. It
also now uses the actual area of the buildings and their intersection, as
opposed to their bounding boxes. I will work on your other requests, but
may not have a lot of time for the next few weeks.

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

Select Duplicate Buildings
Selects duplicate, or near duplicate, area buildings in JOSM's active
datalayer.
A "near duplicate" is a building whose area overlaps another building's
area by more than 50%. Only the first building encountered of an
overlapping pair is selected. This is done so the issue does not have to be
looked at twice. The selected buildings are added to the current
selection.
Currently only works with buildings that are ways (not multipolygons).

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