The RIGIS mission is to monitor, coordinate, and provide guidance for activities related to the use of geographic information system technology in Rhode Island, to support initiatives to implement or use this technology, and to manage and provide access to a comprehensive database of geographically referenced information. Plenty of data is available including 1:12,000 true color orthophotography from Summer 2003 with a 1 meter pixel resolution... nice!
