I worked in some of the early digital uses for archaeology in particular when Intel 387 chips allowed complex trigonometric processing in hardware. While at Grossman and Associates in NYC we had the use of the then developing Rolleimetric 3D photo recording system allowing aerial photogrammetry “brought to earth” so to speak for many types of investigations, ours, the “least contact” recording of a HAZMAT Superfund site in Cold Spring, NY. Measured and drawn from a digitizing tablet the 3D digital information was traced from field photos, using a documented camera, lens and reseau. Other uses were where wall-mounted maps could be recorded for further digital overlays, i.e., aerial photos, digital maps, digitized historic maps, etc. Other uses have been reported for petroglyph recording, sculpture design, i.e. “Crazy Horse” monument, “as-builts” for historic preservation plans, underwater shipwrecks, etc. The quick exposure and treatment of human remains might be also so documented for further research with these digital tools. Not sure if this fits the AAA idea however.

Photo of a smoker with a Rollei for 5/27 – Roger Ebert’s Journal: “Looks a little like James Dean, check the boots, when he had an apartment in NYC. I used an experimental Rollei then MR2 program, that with 8’x10’s, software, Intel 387, and digitizing tablet, created 3D computer vectors from photos. I heard used by Brits in auto accident studies. Canadians were interested after blizzard covered US military air-crash in Gander, Newfoundland before forensics could be finished. Recently bought by Trimble the GPS, GIS company. By the way, the other driver was at fault not Mr. Dean, according to computer reconstruction of accident.”

Draw the Curtains: Gigapixel Cameras Create Highly Revealing Snapshots [Slide Show]

“Researchers are developing cameras that can take digital snapshots made up of more than a billion pixels”

If they are reading this the site referenced has a picture labeled “Seattle OR” which of course should be Seattle, WA. I worked with a Rollei close-range photogrammetry system, a medium-format camera, though 35mm was also available, in development as Intel 80387 (i387) math chip made the process available from a number of photos registered on a large tablet which allowed 3D measurements from software to be obtained from a sequence of photos, (or photo) with the factory documented camera and lens for aberration or distortion. I think this method might aid the science of close-range photogrammetry, where very accurate measurements are needed. Was that pipe on the oil platform, to be replaced, as it was on the “blueprint”, or how much needs to be adjusted, or other uses, accidents, preservation, “as-builts” etc.

Ship architecture query

Stylized schematic, "plan and profile" ship rib construction


In the New York State Bear Mountain Park, I helped record the remains of two centerboard Hudson River cargo carriers for the SHPO with Grossman & Associates. The frames were part wood and part iron, without nuts. The pieces appear joined with a short iron rod through the frame sections and then planked on the outside. The centerboard box, to lower and raise the centerboard in shallow or deep water and counteract the effect on the large sail tipping the hull and to steer, was also made with iron rods through wood without end attachments. I was wondering if anyone is familiar with this type of ship construction perhaps made in the West Point Foundry in Cold Spring, NY. They held records in sailing from NYC to West Point. These, seen abandoned in the background of a photo of a Henry Hudson “Halve Moon” replica sailing by Bear Mountain in 1939 (? Worlds Fair in NYC? 330 year anniversary, the 400th next year) were perhaps similar to the circa Civil War constructions used in transporting the “green sand” for iron moulding mined nearby.
