I'm not sure what you're asking, but given the spec you have, you'll have to shrink your photo to 638 x 638 pixels to get 4.8 m/pix resolution required for PhotoReal scenery. That will result in about 4 256x256 tiles. This is extremely small coverage, and the area covered will be too obvious - it will look like a patch on top of a default scenery. You need to use a far larger coverage at 4.8 m/pix.Misho

I am not conserned about the area coverage. I am asking, should I select the center of North, South, East, and West coordinates?The area of my photo is 80,000 x 100,000 feet or 15.15 miles x 18.93 miles. 24390 Meters x 30487 Meters or 5134 x 6418 pixel as, I figure. Are you saying this photo would be to small.Richard;

"center of North, South, East, and West coordinates?"I have no Idea what that means. In TerraBuilder, you specify N,S,E and W extents of the scenery. The anchor button is used only when you know the resolution. Since you don't have the resolution, UNLOCK the resolution buttons and enter the extents only.>I am not conserned about the area coverage.

Misho;In my photographs for example, the North West Latitude is higher than the North East, The North West Longatude is higher than the South West Longatude.
