Title

DEVELOPING SPACE SYNTAX TOOLS FOR FOSS4GIS: AN EXPERIMENT IN OPENJUMP, ORBISGIS, GVSIG, MAPWINDOW, SAGA, QGIS, THUBAN AND OPENEV  

Abstract

The aim of this paper is to reveal the potential of, in general, GIS and, in particular, FOSS4GIS in the Space Syntax (SS) analysis. For this purpose, firstly existing software programs exclusively developed for SS analysis is reviewed in order to reveal both their capacity to produce the key measures of SS and illustrate the lack of cooperation with GIS and SNA software programs. Subsequently, most popular FOSS4GIS is shortly examined in order to reveal their potential for the extraction of the line-networks and the calculation of basic SS parameters. Later, the plug-ins created for the calculation of widely used SS measures and developed by employing the scripting facilities in several FOSS4GIS is introduced by explaining the core algorithm and specific spatial-topological functions used in the respective software programs. What is evident from this paper is that there are rich avenues for future research in the field of analysis of spatial and social networks if the potential of FOSS4GIS and the common (graph theoretical) background of SNA and SS analysis are properly utilized.
