Kites can be a great scientific tool - it's hard to think of a cheaper aerial platform that can easily lift a kilo or two of equipment hundreds of meters in the air.
We did a multispectral analysis of a part of an ancient Roman road (1st-2nd century BCE) crossing the Ljubljana Marshes. Aerial photos were done in visual light and in infrared (720 nm). False-color NIR-G-B images were done, as were NDVI (normalized difference vegetation index) images. The more data collected, the more clear the road can be seen.
Here is a couple of photos in different wavelengts and imaging techniques - a fuller analysis can be found here
