[josm-dev] Microsoft gains access to aerial imagery

Hi,

There's "corrections" mechanism in twms server
(http://code.google.com/p/twms/source/browse/twms/correctify.py)
The code is not ideal, but it works. (A half a year or so already?)

We're collecting the shifts dataset out of OSM database, for now by
hand. There's already a plugin irsrectify for that.
Shifts are applied to each angle of the request, making sure edges
will glue to on another seamlessly.

There's also unused for now GetCorrections request that can transform
(lon,lat) pairs to their shifted locations on the layer. Can be used
for acquiring initial shifts for simple software, or complex
transformations...

http://play.latlon.org/corr/irs/rectify.txt makes a good overview of
what data we need for the shift.
Any tiled layer can be realigned using twms, including IRS, bing or Yahoo.

What would be nice to have is a software for automatic collection of
those shifts from users' editors.
