Kite topographic mapping - UK campus

Here are some of the results of our recent pilot work with kite photography and structure-from-motion topographic mapping.  We were also able to tie in UTM coordinates to the surface we produced. Although not very visible in these photos at left, we established ground control points using chalk spray paint and our GPS. Our Trimble GEOXH gave us coordinates with 0.10 horizontal and 0.20 vertical accuracies after differential correction, which may not be that useful for the small extent and low contrasts in relief shown here.

I would like to continue refining our kite photography and SFM skills. However, there isn't enough time for me to explore this solely  on my own. If you are an undergraduate or graduate student and want to do an independent study, thesis, or dissertation with these techniques, send me an email.
