[Talk-ca] Surrey 2012 imagery

[Paul Norman]

I added the new Surrey 2012 imagery to my TMS server. This imagery was flown
around April 2012 and has a spatial accuracy of <10cm.

Unfortunately I've only got the 40cm resolution version right now, but this
is still the most recent imagery available for the area. When your imagery
is more recent than the OSM data you don't have to worry about if the
feature you don't see in the imagery is still there.

Details (including the coverage) can be found at

The URL for Potlatch2 is
http://${a|b|c|d}.imagery.paulnorman.ca/tiles/Surrey2012/$z/$x/$y.png and
the "Imagery URL" for JOSM is
tms[10,18]:http://{switch:a,b,c,d}.imagery.paulnorman.ca/tiles/surrey2012/{z
oom}/{x}/{y}.png

Note that when I get the 10cm imagery the JOSM Imagery URL will change to
tms[10,20]:http://{switch:a,b,c,d}.imagery.paulnorman.ca/tiles/surrey2012/{z
oom}/{x}/{y}.png
