[Talk-us] Ohio Statewide Imagery Program

I have recently noticed that Google Earth has incorporated OSIP (Ohio
Statewide Imagery Program,
imagery into their "historical imagery" feature. (Actually, I have to
wonder why it's not used more on the default/current image layer, as
in many places it's newer and/or finer-resolution than that layer.)
Anyway, when the OSIP imagery is visible, the attribution portion of
the window does not use the copyright symbol. Just to be sure about
copyright status, I called Jeff Smith today (his contact info appears
on the OSIP download page) and asked about it. He said that the OSIP
data is all public-domain. (I also asked him if he was aware of OSM,
and he said he was, but I didn't press for more details.)
Since this data is public-domain, and newer and/or sharper than the
Yahoo! imagery*, I think it would be very worthwhile to investigate
ways to easily use it for tracing or general reference in OSM. There
seems to be a WMS service, but I couldn't get JOSM's WMS plugin to
work with it. While I was able to download georeferenced TIFF files
from OSIP, the PicLayer plugin didn't even support TIFF, and I had to
manually align the imagery anyway.
Is there a JOSM plugin that supports geolocated TIFF or MRSID files?
If not, does anyone know a way to align imagery in JOSM other than
fiddling with the move, scale, rotate tools until it fits existing
I suppose I should poke the trac about adding the OSIP WMS to Potlatch.
I acknowledge that using OSIP may be difficult from a programmer's
standpoint, given that it uses Ohio State Plane projections (which are
conics) rather than Mercator.
* OSIP imagery was captured in 2006 and 2007. In central Ohio, it
appears to be the newest imagery Google has. Only Mapquest has newer
imagery, apparently from i-cubed.
