The
purpose of this study is to argue the prehistoric settlement
from the geostatistical analytics, and to introduce GIScience
theoretical concepts into Archaeology through this process.
The subject area is eastern part of the MUSASHINO upland at
middle Jomon period (cal BP. 5400-4500), and has an area of
about 300 square kilometres, the number of 98 archaeological
sites, and the population in highest stage of development
is estimated to be 2000.
First, a database that has the mutual comparability in the
space and site properties was built by using GIS. And the
following four analyses were practiced. 1) Many digital site
distribution maps, which can refer to miscellaneous properties,
were made, 2) Since the geometrical character of its Diagrams
symbolize the topological individuality, the Voronoi method
(as interpolation), was applied using that, 3) The visual
verification between sites was extracted by application of
Viewshed Analysis, and 4) Trend-surface analysis was enforced
using point properties that are archaeological cultural elements.
Finally, the results of these were lined up along the "unconditional"
time-series. I propose considering this approach as Four-dimensional
"4D" GIS.
