That's interesting but not too surprising I guess - do the NAS have anything similar to the cave survey sheets at all? I would have thought someone out there would have done something like this?
NAS do, but this is typically a large A4 sheet pasted onto a chopping board
. Also, their detailed survey techniques involve using tape to take multiple measurements of individual points on each object. Each point is given a 3D position by measuring it's distance from at least two known fixed points on the wreck, which is impractical for our project.
Fred's sheets are fine, after all what we're doing is much more akin to cave survey than what the NAS generally do. We just happen to be laying it over a wreck site rather than through a passage. Al's really only talking about taking out some of the boxes and making others bigger, that's all.
