2005 Land Use

Dataset:2005 Land Use
Source:CMAP
Data Vintage:2005
Update Frequency:As needed
Description:This polygon file represents land use within northeastern Illinois (comprised of the counties of Cook, DuPage, Kane, Kendall, Lake, McHenry and Will) identified to 49 categories, with additional secondary classifications for selected uses. It was created using color orthorectificed aerial photography that was captured in April, 2005; this photography, in addition to numerous GIS reference layers, commercial datasets and internet resources, were used to compare with the previous (2001) Inventory to identify areas of change. The minimum land use classification area size was 1 acre or 2.5 acres (within the City of Chicago 0.5 acre or 1 acre), depending on the type of land use being classified. Land use categories define homogeneous areas and represent features as they appear on the earth's surface. They are not generalized to any other geography.
