seamless has WMS services; they're not tiled. If you want them tiled get a bunch of hardware, stick tilecache on it and serve WMS-C tiles. Doing it in a sustainable fashion does require some forward thinking but it doesn't require a 10 person committee and weeks of discussion on things like voter eligibility for a non-existent project. OR continue to pressure USGS to do it.
The other answer is that you can just go to ESRI, Google, or Bing and use their tiled services which are going to be free enough for most people. This project isn't like openstreetmap where you'll have people go out and create imagery and upload it. A kite photo mosaic of the US? While that'd be cool it sounds like a nightmare from aesthetic, management, and QC aspects. Right now I still don't see what's compelling about tiling NAIP. - bri On Wed, Dec 9, 2009 at 9:28 AM, Jeffrey Johnson <[email protected]> wrote: > Care to share an endpoint for a tiled version of the entire NAIP dataset? > > USGS are not interested in serving tiles.
