Presentation on Participatory GIS by Danielle Bamford and Chrissa Stroh of NOAA Coastal Services Center and Becky Szivak of ACE Basin NERR (November 5, 2009). Participatory GIS is a practice in which local communities share their knowledge and opinions to help generate maps to inform management and decision-making. Participatory GIS fosters discussion and collaboration among stakeholders and can capture important knowledge from underrepresented groups. This presentation described the use of Participatory GIS in two coastal projects: the Edisto Island Preservation Association’s project to make recommendations on an update to the local county comprehensive plan and the Great Works Regional Land Trust’s project to develop a strategic plan for the land trust's conservation work. The presentation also described new resources for coastal resource managers interested in using Participatory GIS.
