A novel, I believe, adaptation of the Harris Matrix was made by Rick
Ahlstrom (1992), while a Ph.D. candidate in anthropology at the University
of Arizona.
 
Rick's research focused on architectural changes through time at Walpi,
a Hopi Indian village on First Mesa in northeastern Arizona.  His data
base included  a corpus of photographs of the village.  The photographs
were made from a variety of directions, some were dated, others were undated,
mostly from the period 1880-1940.
 
The challenge was to attempt to date the undated photographs to enhance their
value as visual depictions of architectural change.  What Rick did was to
treat each photograph as a unique "stratum" in a Harris Matrix.  The dated
photographs were placed in their (apparently) proper chronological sequences
(separate sequences for each of the principal elevations of the village) and
the undated photographs were compared to the dated sequences by examining the
visible architectural features.  Rick found it possible to place many of the
undated photographs in relative position within the sequences, sometimes to a
fairly narrow range of possible dates.
