Quote:quote:I agree with Mercenary on the potential of close-range colour photogrammetry. The ability to process these images quickly on site and to add layers of interpretative data was essential to the recording process at Silbury, and in my view it worked extremely well. More recently I've seen some fantastic work done at Wilanow Palace near Warsaw by Polish National Heritage Board (Kobidz) archaeologists where colour photogrammetry of soft deposits and masonry structures was carried out, with interpretation added, and the results seemed to be the most effective integration of buildings and excavation recording and presentation that I've seen so far.
The digital photogrammetry from Silbury is impressive. It should be pointed out that it has generated a very large data set Okay, what is a large file today is small tomorrow but can't blindly walk into capturing such large datasets as it has longer term implications. The ADS Big Data project has done some really good work on this http://ads.ahds.ac.uk/project/bigdata/
Any work that relies on 3d scanning or photogrammetry at least for the next few years will require high powered computers and high costs for long-term archiving that can't be ignored.
