Abstract
Through the calculation of cost surface, GIS enables site catchment
analysis to move beyond models with simple geometric circles to allow for
irregular ranges by considering the different costs of transportation over
landscapes. Taking both terrestrial and marine data into consideration, the
different accessibility of resources within a site catchment can be understood in
more detail, and archaeologists can use this information to create a model of
interaction between sites and their environment.
According to the location of six sites from the O-luan-pi III/IV phase, and
through the analysis of cost-surface and viewshed of digital elevation model
(DEM) in GIS, I divide the coastal area of the O-luan-pi peninsula into four
different landscape rooms. Two landscape rooms are separately occupied by a
single site, and the other two landscape rooms each have two sites within them.
It would seem natural to expect that catchments of sites sharing the same
landscape room would overlap and that the activities of the sites on land would
influence each other on land. However, through the analyses of current and
wind data, it appears that sites sharing the same landscape room have
different accessibility to terrestrial and marine environments. These variations
may have led those sites to maintain their independent site catchments rather
than competingwith each other for resources.
