So we are really into archaeology, and we are thrilled that a kite can be a really useful tool for discovering and monitoring of archaeological sites. Aerial archaeology has been a thing for a couple of years now, and we gladly jumped aboard the hype train – uncovering a Roman villa, documenting a prehistoric landscape, and observing the first road through the Marshes.
Now we made a step further: we acquired a modified action camera specially designed for agriculutre – the AgroCam Geo NDVI.

This near-infrared – green – blue multispectral camera detects small variation in plant growth, and enables simple computation of the NDVI – normalized difference vegetation index. And this is really useful in archaeology, since grasses and crops grow poorly above a bured wall, and much better above a buried ditch.
So we went to test the AgroCam on a kite above a potential archaeological site Otok in the middle of Ljubljana Marshes, and we found …

There are many reasons for that – maybe the remains are buried too deep, maybe the soil is too dense for plants to feel the differences, or maybe there is really nothing there – so we werent really disappointed.
What’s more important, we had fun! We flew two kites and caught one on a near-infrared shot (see the hexagon by the road – it’s our venerable blue Rokkaku!) …
… and we did a NIR selfie! 🙂
And the tumbling AgroCam caught the carrier kite in the sky. The clouds were uniform for a naked eye, but very dramatic in near infrared!
To wrap up this KAP archaeological session – many things were learned, fun havse been had, and there are many sites just waiting for our kites to soar above them!
