Adding the fourth dimension to participatory 3-D modelling
This article focuses on Participatory 3-D Modelling (P3-DM), a tool which merges Geographic Information System (GIS)-generated data and peoples' knowledge to produce a stand-alone relief model. P3-DM was used in the Philippines, by the National Integrated Protected Areas Programme (NIPAP), to give due weight to the interests of local communities in delineating protected area boundaries, identifying resource-use zones and formulating policies on protected area management. The model provides an efficient, user-friendly and relatively accurate spatial research, planning and management tool.
