Thank you, Due - valuable info on the GeoEye.

That is INCREDIBLE resolution for Satellite data. (sic. publicly available, even if commercial - vis a vis - military satellite imagery which reputedly has been able to read the brand name on a pack of cigs for well over a decade or two - unconfirmed and unconfirmable sourcing on that tidbit.)

I was unaware of GeoEye.

Definitely on my 'keeper' list - when I am working - this info is worth it's weight in gold.

Went to the NAIP mapping (upon which the USGS dataset is based) - and was APALLED at how poorly the servers are working now. Degraded to almost worthless from a little over 2 years ago. Surprise, surprise - bet their budget hasn't been cut any either.

You're right about much of Google's imagery being aerial. I know for a fact that the NJ imagery is the latest USGS orthophotography.

The highest resolution commercially available satellite imagery is from GeoEye (GEOY). The GeoEye-1 satellite was launched three years ago with .41m/pixel panchromatic and 1.65m/pixel spectral sensors. They combine these to produce .5m resolution color imagery. Earlier standard was the Ikonos satellite with 1m resolution. Check it out.
