From
Ray Di Ciaccio’s Thesis from 2009 which documents his development of a GIS for
ancient sites (he calls his product DAMP):
“One
of the first problems I encountered with the survey data is the lack of global
geographic coordinates for the sites.
Both the AEP and the KSP use different methods for presenting the geographic
locations of their sites; the AEP uses a local coordinate system that
corresponds with a map included in the publication, and the KTS gives the
coordinates as they appear on the British Admiralty Map. Obviously for the purposes of creating a DAMP
map that will include the sites from these projects (or some other survey
projects), the localized coordinates are
of little help; in order to position a location on the map, one needs the
geographic latitude and longitude of that location.
"For
some reason – perhaps because of the relative novelty of GPS technology or the
ease of using local maps to plot the locations of sites – geographic latitude and longitude have not normally been provided for
the sites of a Greek survey project. [54]”
“[54] Even a more recently published survey, PRAP ... does not provide such information about site
location.”
I dropped a couple of Mr. Di Ciaccio's footnotes. The emphases
are mine.
