We are providing them with the individual files as well. My computer is churning away on that right now. It will be done sometime tomorrow morning.

We fully expect them to complain about the file size. We will point to the bid specs and say that is what was specified. Right now each image covers 6,000 x 6,000 feet, just over a square mile. At the mega resolution they wanted it becomes a 1.6 gig tif file. The only way to make the file smaller is to lower the resolution or cut them up into more pieces. The cool part of geo-coded images is that each image knows where it belongs. So all you have to do is open the file and it pops right into position. The problem is you are looking through a list of hundreds of files to find the next file you need.

In the end we make a really neat file that is a multi-resolution file. If you zoom out to see the entire thing it displays all the information you monitor can show. As you zoom in to an area it bring in more data. That will be a monster file as well. We will have to deliver the project on a 2TB hard drive.

It is cool to keep drilling down into the file and see the detail. You can tell the color of clothes a person is wearing. You can't see anything that would identify them, but you can usually tell if they are male or female.
