Color Aerials

I'm getting some strange results with the color aerials. Everything is tinted red, I don't think this is what you meant by "color". The image is from Austin, TX.

Unfortunately that's just how they are for Texas (and PA, too).

Check the coverage map here:

You can see that those two states are red (no idea why).  Everywhere else is normal color.

Yup.

Perhaps someone should inquire at your state gov't as to why they'd like to think they live on Mars.

Republicans in TX, no idea about PA.

Just to end the confusion, these "color" aerial photographs are infrared aerial photographs. Below is a short description copied from here.  My guess is these states probably haven't re-flown the state with newer photography yet.

The primary use of color infrared photography is vegetation studies. This is because healthy green vegetation is a very strong reflector of infrared radiation and appears bright red on color infrared photographs.
