This technique works well for smaller areas, but when I tried running the
license check plugin on a 5 GB .osm file it was unhappy.
With very large files, I do manage to get a result from the plugin but
JOSM's performance rapidly deteriorates (no doubt due to my hapharzardly
implementing the plugin because as soon as I switch off the license
check layer things work smoothly again).
In these cases I tend to:
1. load very large file
2. run license check
3. visually identify problem area
4. drop license check result layer
5. select (one of a number of) problem area(s)
6. invert selection
7. purge data
8. re-run license check
That way, I can zoom in on problem areas without always having
everything loaded.
I have all the code
written to do this automatically except the logic, which I'm finding oddly
difficult.
In addition to the logic in *my* code being difficult, it is also not
the ultimate algorithm; while there will be little difference between
the WTFE algorithm/license change plugin and the actual license change
bot, there may be situations where they make different decisions.
