Perhaps shot from horseback? I say that as I have had classes with
Edward Lanning ("Peru before the Incas" and co-author of "Pre-Hispanic
America") and worked for Joel W. Grossman whose Ph.D. was in
prehistoric Peru and worked for UNESCO there until an assistant was
blown up at a podium, perhaps by "Shining Path" he's related.
Incidentally the forensic college cited, Henry C. Lee Institute of
Forensic Science, has been involved in major public cases, the O.J.
Simpson trial, the Phil Specter trial, etc.

I once worked with close-range photogrammetric developers from Canada,
Prometric Technologies, which tried to demonstrate to the US FBI (and
similar agency in Canada) the benefits of the technique back in the
early 1990s, where we used it for plans and profiles on a couple of
sites, particularly of historically unknown contamination and I
photographed a number of profiles and plans of archaeological
excavations in the West Point Foundry, Cold Spring, NY that way and
rectified and produced 3D data some of it plotted from that then
developing system. It can have many uses in archaeology and
preservation then currently in use in England for automobile accident
investigations.

In the interest in developing standards for this type of recording
shown in the NY Times, I have found that at least in the Bowdoin Park
Dutch Reformed burials back in the 1980s (in former JP Morgan
summerplace, as the federal supplied sewer money ran out) and the
so-called "First Almshouse" burials in 1999 in New York City's City
Hall Park, the oldest city hall still in use as one in America, on the
former green, to be lacking. One with grids made from window screens
taken from a step ladder and other basically just hand sketched in, to
me, troubling procedures after working in more dimensions, the 2D
digitizing from photo interest "points" becoming 3D data for further
use. For example the Metropolitan Cathedral in Mexico City may be
measured after a time of photos to see if any of the stone blocks have
moved, or because of the extreme accuracy that can result, the pipes
in a nuclear power plant.
