Mapping and analysing medieval built form using GPS and GIS

Abstract

Drawing upon recent research experiences of using a Global Positioning System (GPS) and Geographical Information Systems (GIS), this paper sets out how spatial technologies can be used in the study of medieval built form. The paper focuses particularly on the use of differential GPS and ArcGIS in mapping and analysing the plan of Winchelsea, an English medieval 'new town' established in the 1280s. The approach used to conduct this research is outlined here, with comments on the practicalities of using GPS and GIS in historical urban morphology. Although the research on which this paper is based is at a preliminary stage, the paper offers a working method for those interested in using spatial technologies to build upon existing methods of morphological study, namely town-plan analysis and metrological analysis. Some preliminary research findings relating to the planning of medieval Winchelsea are also presented.
