Order in movement: a GIS approach to accessibility

The aim of this paper is to extend the range of current analytical procedures that archaeologists use to understand movement. In particular, how a landscape becomes ordered by simply defining a destination. More specifically, this study proposes the derivation of a focal mobility network, i.e. the network of most likely paths towards a given destination, and explores several of its applications within a landscape archaeology framework. The suggested extensions are based on existing standard procedures within most GIS. A series of synthetic control surfaces and an archaeological study focused around Iron Age hillforts in Galicia (NW Spain) are used as case studies to illustrate different analytical possibilities.
