This report is part of a multiyear research and action project by PolicyLink, the Urban Institute, and the Lincoln Institute of Land Policy to advance the field of parcel data systems and their application to community revitalization and equitable development. (See inside back cover for more information about the participating organizations.) It builds on research summarized in a recent Lincoln Institute working paper, The Potential of Parcel-Based GIS in Community Development and Urban Land Management (Chandler et al. 2006), which was presented to a group of community data systems experts in June 2006. At that meeting, attendees expressed the need for case studies to illustrate the value of integrated parcel data systems for the practice of community development. This report represents a first step toward cataloguing the most promising applications of these land information systems.
