About the DataMost of the data used to create the printable maps available from this site and in the interactive mapping application were developed by the University of Rhode Island's Environmental Data Center for the Rhode Island Geographic Information System (RIGIS). Some data were also developed by R.I. Department of Environmental Management (DEM). All data used on this site are described below with links to metadata records. To download spatial data developed for this site in support of restoration planning, please see Downloadable Data. To download RIGIS data, please visit the RIGIS Web site. Base Layers | Hydrography | Natural Resources | Socioeconomic Data The base layers of the maps available on this site include:
