Near-infrared kite aerial archaeology

Hi again :-)

We like to do aerial archaeology with our kites, and a couple of days ago the magnificent dr. John Wells donated us an infrared modified camera, a Pentax WG-10 with the IR block filter removed (an amazing gift, we are still in awe - sending big thanks).

So we took it for a test, and we flew the venerable Rokkaku over a field in Kašelj near Ljubljana, Slovenia, where a Roman villa rustica is supposed to be. And maybe - maybe! - we got something. The full report is here on our KAP website, a couple of photos are below.

NDVI (normalized difference vegetation index) created from a near-infrared and a normal photo. NDVI brings out subtle differences in plant growth (wheat in this case) that sometimes correspond to bured walls and ditches.

And we got a preliminary reply from professional archaeologists we send these photos to: "Looks promising, worth a closer look and a second visit!" :-)
