Yes it
is true - the NAIP 2011 data were delivered a few weeks ago. David Kirouac
here at MEGIS is processing the data for WMS, which should be done next
week or so. We will send out a note when the WMS is ready. Based on
just a few samplings, I would say the clarity and color-balance is not as good
as 2009, but definitely better than 2007 (and way way better than 2006 which was
2m resolution). There is some haze in 2011 as well. A sampling in Portland
shows the differences below. Nevertheless, NAIP 2011 will be the most
current data for Maine we have, and thus highly valuable just for that
reason.
We are
in the midst of revamping our orthoviewer to get it out of WebADF, and when that
happens (February-ish) we will also enable the download of JPEG2000 quads for
NAIP 2011 data.
Also I
confirmed with USDA that NAIP 2011 was collected with a fourth infrared
band. This band is not in the county mosaics that you can download (nor do
we have it), but it will be delivered a bit later.

In case there are
others like me - in the dark - I just noticed that the NAIP 2011 imagery
is available from http://datagateway.nrcs.usda.gov/
Glancing over the metadata, resolution looks to be expected on par with
the 2009 stuff. Am waiting for the first extraction to download, so can't just
yet speak to image quality.
