![]() ![]() The practice integrates several tools and methods whilst often relying on the combination of 'expert' skills with socially differentiated local knowledge. A good PGIS practice is embedded into long-lasting spatial decision-making processes, is flexible, adapts to different socio-cultural and bio-physical environments, depends on multidisciplinary facilitation and skills and builds essentially on visual language. GIS-based maps and spatial analysis become major conduits in the process. PGIS practice is geared towards community empowerment through measured, demand-driven, user-friendly and integrated applications of geo-spatial technologies. Participatory GIS implies making geographic technologies available to disadvantaged groups in society in order to enhance their capacity in generating, managing, analysing and communicating spatial information. PGIS combines a range of geo-spatial information management tools and methods such as sketch maps, participatory 3D modelling (P3DM), aerial photography, satellite imagery, and global positioning system (GPS) data to represent peoples' spatial knowledge in the forms of (virtual or physical) two- or three-dimensional maps used as interactive vehicles for spatial learning, discussion, information exchange, analysis, decision making and advocacy. PGIS combines Participatory Learning and Action (PLA) methods with geographic information systems (GIS). ![]() Participatory GIS ( PGIS) or public participation geographic information system ( PPGIS) is a participatory approach to spatial planning and spatial information and communications management.
