I saw a bunch of the 3D photo viewers (I won't attempt to spell the names) in an engineering class back in college. A whole room full of them, with piles of the stereo photos just waiting to be tossed I think. On a slow day we set one up and checked it out. It was amazing, totally 3-D. You felt like you could touch the trees! Most of the photos were of the forests in northern idaho, but I'm guessing that photos of more urban areas would be cool too.

I have a question based on one of these recent posts. Driving around Boise here, I've often noticed some large X's or painted in odd places. Could these be some of these markers?

We use aerial photographs quite often in the early stages of design (I'm an architect), to help the building and the site design fit into the area. I love to look at older aerials to see how much this area has changed in the last 50 years. Boise is growing so quickly that it really is amazing to see what was. I can't remember who does it, but someone around here actually "stitches" the photos together and makes a large mosaic of the entire valley each year. You obviously can't see a whole lot of detail fro that high up, but it is nice to see everything at once.

Not that it really applies to this group, but just in case anyone is interested...there are quite a few websites out there with all sorts of aerial photo's. Here in Boise you can get the entire metro area at http://www.compassidaho.org/maps/200...s/2003map.html This is a planning agency and the photos are actually done by the Fed's so they are public domain. I assume that many areas have something similar.

This site... http://www.jpl.nasa.gov/ has photos from way way up from satellites, as does this one...http://www.spaceimaging.com/ which has a nice gallery page.

This site...http://terraserver.microsoft.com/ has all sorts of capabilities, but from what I've found the photos are a bit old. They can be cool too though.
