I love LIDAR and PTM

by Simon at 19:03 04/10/10 (Blogs::Simon)

Polynomial Texture Mapping combined with LIDAR data is a fabulous way to re-light landscapes and play "I can spot cool stuff" with :-)

For example, on Wessex Archaeology's website, Tom Goskar's blogged about using PTM with the LIDAR data of the Stonehenge World Heritage site. And it has a way cool Java applet you can have a go with.

Now, what I want to know is: Is that a new henge with an avenue aimed at the Winter Solstice sunrise I can see?

I'm sorry, it was a very bad curry I ate at the festival in '84, and there were no toilets...

ROFL! But good point - that's not where the stage was is it? My memory is slightly hazy...

The stage was closer to the stones, I should anotate the picture really before my memory fades :-)

The relative positions are correct, not sure of the absolute the further up the field it gets...

I also spotted this when I first made the PTM, and made a number of images of it. I've mentioned it to a few people, and hopefully some recommendations will be made to have the area looked at. You're the only other person to spot it, as far as I know :-)

Worth a wander up there to see what it's like on the ground?

I've also just spotted that the Stonehenge Riverside Project have got some money from Google for a project called "Google Under-the-earth: Seing beneath Stonehenge" - to make data available. Sounds great: http://www.bournemouth.ac.uk/caah/stonehenge-riverside-project/google_seeing_beneath_stonehenge%20.html
