  • USGS ortho detail

    Here is an image of my neighborhood captured from the Terraserver site:



    And here is the same area captured with WW1.3.1 (after reloading cache with F5):



    If Terraserver is providing the images for the urban orthographic illustrations, why can they be accessed via the Terraserver site directly, but not via WW1.3.1?

    Well, for one your not getting in close enough. What is the lat and long of the images? What WW displaces is the same as what terraserver sends out since they are hosting the data.

      When I attempt to move in closer, I see:



      The long/lat indication is included in the photo. Pressing F5 results in a reloading of the tiles. Leaving the system up for an hour or two doesn't download any more tiles.

        I just tried that exact location and I don't get an image as clear as the Terraserver screenshot you posted, but it's definately much better than what your seeing in WW. Not sure what the problem is. Also, I get the same effect if I zoom in too far.

        Maybe something going on with elevation data in that area

          Thats a known bug, try setting vertical exageration to 0 to get higher level images.

            Thank you!!!! Setting the vertical exaggeration to zero did the trick! True, it's not exactly as clear as the Terraserver picture on close examination but very close and certainly much better than that psychedelic experience.
