Grassroots GIS

The use of Geographic Information Systems (GIS), by community based organisations in society is an important phenomenon to study. This book examines in detail the design and implementation of Public Participation GIS (PPGIS) in Dublin, Ireland and New Orleans, Louisiana. This book spans several years of regular observations of local residents and workers in Community Based Organizations (CBOs) engaged in community development activities and initiatives involving "Grassroots GIS". Public Participation Geographic Information Systems have the potential to affect positive change in the flow of information and increase communications between residents, those working for CBOs, urban planners and decision makers. This book offers insights into various processes of community activism and engagement using these GIS tools. Members of community based organizations seek answers to questions on the nature, quality and usefulness of the various kinds of data and techniques available and readily employed in community development and planning contexts. This book provides these answers and offers sound and practical GIS applications to assist the "grassroots".
