These ESRI shape files are of National Park Service tract and boundary data that was created by the Land Resources Division. Bounds of the tracts and islands are photo interpreted from 1996 ortho photo mosaics created by the University of Rhode Island for the park. Tracts and islands are consistent with the legislated boundaries defined by PL 104-333 which also references map number BOHA 80,002. Tracts are numbered and created by the regional cartographic staff at the Land Resources Program Centers and are associated to the Land Status Maps. This data should be used to display properties that NPS owns and properties that NPS may have some type of interest such as scenic easements or right of ways.
