Participatory GIS — a people's GIS?
In a recently published paper Christine Dunn argues that recent years have witnessed a burgeoning of applications of GIS which grant legitimacy to indigenous geographical knowledge as well as to `official' spatial data. By incorporating various forms of community participation these newer framings of Geographical Information Systems as `Participatory GIS' (PGIS) offer a response to the critiques of GIS which were prevalent in the 1990s. This paper reviews PGIS in the context of the `democratization of GIS'. It explores aspects of the control and ownership of geographical information, representations of local and indigenous knowledge, scale and scaling up, web-based approaches and some potential future technical and academic directions.
