I forgot to mention that the company representing the Rolleimetric MR2
system, working with them in Germany and with Schneider Instruments in
New York, on Long Island, was/is the Canadian company, Prometric
Technologies with Andrew Lane and Ray Masagin (apologies if the
spellings wrong). They have worked on as-built landmark recording in
Canada, and other projects (petroglyph recording photogrammetrically)
as well as assisting Grossman & Associates, Inc. on the West Point
Foundry deposits in Cold Spring, NY.
