ASSESSING SPATIAL DATA QUALITY OF PARTICIPATORY GIS STUDIES: A CASE STUDY IN CAPE TOWN
K. Musungu Department of Civil Engineering and Surveying, Cape Peninsula University of Technology, Cape Town, South Africa
Keywords: Spatial Quality, Participatory GIS, Informal Settlements, Community-Integrated GIS, Quality criteria Abstract. Participatory GIS (PGIS) has been prescribed by scholars who sought to find a means to enable more equitable access to GIS data, diversifying the types of knowledge captured by a GIS and re-engineering GIS software. The popularity of PGIS is evident in the various studies and contexts in which it has been utilised. These include studies in risk assessment, land administration, resource management, crime mapping and urban design to mention but a few. Despite the popularity of PGIS as a body of research, little has been done in the analysis of the quality of PGIS information. The study investigated the use of data quality criteria commonly used in traditional GIS systems and shows that it is possible to apply the criteria used in traditional GIS to PGIS. It provides a starting point for PGIS studies to assess the quality of the product. Notably, this a reflective exercise on one case study, but the methodologies used in this study have been replicated in many others undertaken by Community Based Organisations as well as Non-Governmental Organisations. Therefore the findings are relevant to such projects.
