Paul,The screen shots certainly look impressive. There is one item - I have tried photoreal but always thought that the result was less clear than the synthetic scenery. I like to fly around 2000 to 3000ft AGL. Could you show some lower level views, such as a side view from inside the Cessna. And,is my observation true, in your opinion, or did I have something messed up?Finally, where did you get all of the aerial photos???Dick Boley KLBE

Most important you have to have the best data to begin with, I have seen plenty of 2meter products that were sampled badly to 2m and they never would resample as good as some well sampled 5m products so its always good to shop around for data and learn some of the ways things get done.Take care.

Paul, just got back in town...your very welcome if I've helped you. My pleasure has always been to see us all sharing to learn new things. The complements on your work above make me want to see it, but alas...the link seems not to work for me. Not sure why, but I will say one thing, your rochester project always seemed to be just out of reach..hopefully this means you're back...your work has always looked top notch!Best,Bob

Dick, there is a tradeoff that's natural, as the real world doesn't lend itself to low resolution pixelation, and nicely aligned pixels (clear views close up) tend to look more artificial from 3000'. Its more about what floats your boat than anything else. As Paul has said, there are ways to optimize (likely true for both methods), and once you've optimized, you just choose what you prefer. Some combination methods are possible, using vtp2 polygons and photoreal imagry. doing this, you can use default landclass in customized fashion combined with photoreal in patches which may serve to minimize your sense of unclear imagry from low down. Best,Bob B

You wouldn't believe what some of these places do! Droooollll!!!
