In our next layer of the site data map, we're looking at near infrared imagery collected from the aerial survey.

We'll have a chat with aerial surveyor Adam Stanford, as well as data whizz Pete Spencer, to put these models into context and explain how the various techniques can help us to identify archaeological features or otherwise inform the process of piecing together the past.

Love the maps and models! Would it be possible to show the location of the trenches on these. (I don't mind if this has to be nearer the time of the release of the episode) It gives me some insight as to where you were digging - based on the geophys and aerial information.

ooh. there's all sorts in there when you start to look closely. I guess one can look too closely, though... and see forms that aren't really there? Like rabbits in the clouds?

Graham Stokes

What do these colours mean or designate? Purples, black or dark blue, yellows, reds?

Jill Bray - Author

I am assuming (rightly or wrongly) that the purple areas are the cooler areas - representing trees/vegetation; and the yellow areas are the warmest.

Great images, presumably the IR is reading latent heat stored in the ground, is this greatly effected by time of day and seasonal weather?

Jenna Leigh-Thompson

Is there a clue in where going with map being expanded in one area?

Jenna Leigh-Thompson

Last question, the north eastern enclosure boundary clearly projects around the chapel... as Stewart all ways said, why is it here...so is that actually a trackway or road that extends beyond the site.... time to find the site on map!

Jude Edling

Love the maps, I've got to figure out how to see them side by side.

Eelco Kruidenier

The blue, purple and yellow are not explained in the key. And what is explained in the key is not on the map. And again it is too small to read.

Pia Fredfeldt

I kindly wish for a video, where the different layers get explained.

Hi Pia, we're going to do that in due course. Watch this space.

If you want to make the map and legend larger, click to enlarge, then right click "open image in new tab"...This will allow you to magnify it more. It would be nice if they'd just show them in the original resoulution, so we can actually read the legend!

Kay Theriault

Are reds, oranges and yellows warmer and blue, purple and black cooler? The legend doesn't cover the colour temperatures....

i would imagine it the same as earth versus rock. Darker would be rock compared to earth being red orange as the sun would warm this quicker and take longer to warm rock. so maybe the darker would identify the building materials for example.

Kay Theriault

OK, I hadn't thought of it that way. I appreciate the insight. :)
