Minnesota. Department of Natural ResourcesThe Aggregate Resource Mapping Program (ARMP) began in 1984 when the Minnesota Legislature passed a law (Minnnesota Statutes, section 84.94) to: - Identify and classify aggregate resources outside of the Twin Cities metropolitan area; - Give aggregate resource information to local units of government and others for making comprehensive land-use and zoning plans; - Introduce aggregate resource protection; and Promote orderly and environmentally sound development of the resource. Provided here is a compilation of GIS data produced by the DNR's Aggregate Resource Mapping Program. Also provided is the aggregate resource GIS data from the 7-County Metropolitan Area mapped by the Minnesota Geological Survey (MGS).
