I work smart, not hard.
I am building a compressed mosaic. I took 84 tif files 2.9 GB total and compressed it to one 190 MB file. It covers 112 SQ miles. Here is a very tiny chunk of the image. This is what the middle of nowhere Texas look like. Some engineering company had us fly this for their client. They will be doing some sort of wind power site here.
We did a contour map of this entire area. We flew it in stereo so we can measure the relief of the ground.
