资源简介：
The MassGIS Land Use datalayer has 37 land use classifications interpreted from 1:25,000 aerial photography. Coverage is complete statewide for 1971, 1985, and 1999. Additionally, more than half the state was interpreted from aerial photography flown during 1990, 1991, 1992, 1995 or 1997. The 15 towns on Cape Cod also contain land use data for 1951. Please see the Land Use Status Map, which displays the years for which land use data were interpreted for each town. In ArcSDE the layer is named LANDUSE_POLY. Note: Complete metadata is available within the downloaded zip file. This metadata can be viewed with ESRI ArcGIS software, and can be exported to FGDC and ISO metadata formats.
