| Abstract | This data set contains land cover boundaries and associated attributes. From 1999 to 2002 land cover boundaries were created by interpreting, delineating, and digitizing vegetation communities and impervious surfaces. The Minnesota Land Cover Classification System (MLCCS) was used to interpret land cover types. MN DNR color infrared photography was used for interpreting vegetation along with the following GIS data sets: national wetland inventory, county biological survey, hydric soils, physical water features, fieldline boundaries, and woodline boundaries. Land cover boundaries were delineated on 1997 Metropolitan Council Digital Ortho Quarter Quads (DOQQ'S) from 1999 to 2000 (1991 United States Geological Survey DOQQ's were used for high water areas that were flooded on the 1997 DOQQ's), and on 2000 Metropolitan Council DOQQ's from 2000 to 2002. Resulting interpreted and delineated land cover polygons were field checked where visible or accessible from roads or public property. Polygon boundaries were then digitized in ArcInfo at a 1:3,000 scale. Minumum mapping units of 2 acres for cultural areas and 1 acre for semi-natural and natural areas were observed. |

| Purpose | The land cover inventory data set is vital to supporting Dakota SWCD conservation practices in Dakota County. The data set was created as a natural resource planning tool to measure current levels of impervious surfaces and to serve as a natural resource inventory of all vegetation communities within the County. The inventory allows SWCD staff to work more efficiently and effectively by responding to customer requests more quickly and accurately. | |||
