Yes indeed... have to agree with you on all points. I like this non-invasive archaeological style as well and often wonder if our predessors were not throwing away the most valuable aspects of digs with their more rugged approach...

I like that idea of using electrolytes to measure for corpse location. There was something similar a few years back in Guatemala & Honduras, where a lot of Mayan architecture and structures remain buried in jungles. They found a way of measuring a difference in folliage from outer space via - well, it seems that the stones used to builid certain structures like Tikal/Copan/Palanque use limestone (I think), and that trees and shrubs growing on old sturctures absorb more lime, thus it has some affect on Chlorophyll, so that they could utilise NASA satelites to distinguish and area of the forrest with such an affect with infrared or UV imagery or the likes, and from there they could then send out a team to probe it, as appossed to just prodding around in the dark...

I just finished a book this summer about a Henry Rawlinson deciphering Cuniform around the 1850's out in Persia and Mesopotamia... Very interesting, but when you read the descriptions of how they (his peers) dug into sites and then pryed out great sculptures with crobars to send home to museums in London & Paris... its kind of harsh to modern ears but I guess it was a different time then! .. and sometimes, they even had to cut large stone sculptures in two to make them more transportable and manageable!!!! Ouch.

However, I do like how Dr O'Kelly left a certain percentage of Newgrange unexcavated so that it would be available for future scholars and better techniques... now there's a forward thinking individual who probably would have been a technological innovator had he not passed away so young.

"I often wonder to what extent archaeology is the developer of such technologies, rather than the borrower." Absolutely, good scholars are often multi-disciplinary, so I think that you should always get a fair amount of symbiosis from talented individuals from many facets of the sciences. Also, having people from opposite polar extremes come together, helps to let people see different approaches to using devices/technology in a way or a manner in which an engineer, dentist may never have thought of and vice versa.

Must say... I've enjoyed this thread today, although, shame on me for not having discerned the football pitch that Simon.d refers to in your quoted post. I'll go back and have another look.

Felt the exact same, but Simon.d then uploaded this link which rectifies this problem... and you can to and fro to your heart's content without experiencing a seizure

Just use the left/right arrows to alternate

Definitely agree that destructive archaeology will be somewhat shunned in the future.. Even now it's difficult not to cringe when seeing something like this:

I'm no expert on the technologies like GPR, magnometry, resistivity etc, but I'd be confident all the same that improvements in resolution, material identification and their capacity for 3d representation of what is being scanned is bound to improve in the coming years.. I also think improvements in the post processing of data acquired using such techniques could potentially aid in discerning some of this information, in a similar manner to which photogrammetric post-processing can portray topographical information hidden within photographic data.

Absolutely.
If you look at some of the print-outs from geo-phys surveys from 10-15 years ago compared to today, they look positively primitive (dot matrix printers ).
Having said that, I am a bit surprised at the relatively slow integration of advances in 3d visualisation technology, but I suspect a quantum leap is just around the corner.

Just started down the road of kite aerial photography in the last few weeks, an even more affordable platform than the plane (€40), but more fiddly to get to grips with (so far).. Had the camera up at dusk only to date, so images aren't great.. Will hopefully see a bit of sunshine on a day off sometime soon!..

Does anyone know what mapping system is used in the second image on the above link? Many thanks.

There's a little double page in the National Geographic this month about Satelitte Archaeology. It focuses on the work of one arch, Sarah Parcak, University of Alabama at Birmingham, who has used it to identify previously unseen features in Egypt.
"in 2011, relying on infrared satellite pictures, Parcak and her team identified 17 potential buried pyramids, some 3000 settlements, and 1000 tombs across Egypt." They have an example layered drawing of the city of Tanis.

Nothing ground breaking in the article tbh, it's very short, but if anyone is interested I'm sure her crowd at the University must have released some more specific info on their work to date.

p. 60 by the way !

An interesting piece on photogrammetric modelling.

(by the way hypr3d has been taken over by a biz by the name of 'Cubify' and is no longer free, as far as I can see )

Noticed that the other day too ... 123dcatch (and a few others) are still free, and I'm finding it to be a superior service interms of deciphering detail. Downside with it is it tends to bring in some erroneous crack like features into the model, but not a major issue...
