{ "currentVersion": 11.3, "cimVersion": "3.3.0", "id": 0, "name": "DNR Sand and Gravel potential", "type": "Feature Layer", "description": "This spatial dataset of sand and gravel resource potential is based on a compilation of GIS aggregate resources (sand and gravel, crushed stone) reconnaissance scale data spanning twenty county projects completed over a number of years (1987-present) by the DNR's Aggregate Resource Mapping Program (ARMP). The attribute data available varies as a result of the varied years of completion and changes in databases structure and verbiage over time. The past project GIS data has been loaded into the current file geodatabase used by the Aggregate Resource Mapping Program. Therefore the data from the most recent completed counties (Kandiyohi, Aitkin, Stearns, Kanabec, Olmsted) have the most complete attribute table, while the earlier mapped counties (Sherburne, Wright, Isanti) have limited attribute data. Digital sand and gravel resource potential has been delineated for the Sherburne County Project completed in 1987 and continues today.This spatial dataset can consist of information about the geology, geological characteristics, and sand and gravel potential for 21 counties in Minnesota. Recent completed maps include data fields related to the surficial geology of the map unit, including a major sediment, minor sediment, landform, surficial geology description, probability (unit certainty), depositional variability, and lobe provenance. Five fields relate to sand and gravel characteristics, including sand and gravel probability, quality, texture, overburden thickness, and sand and gravel thickness. These characteristics were used to calculate the aggregate potential of the map unit for sand and gravel.", "geometryType": "esriGeometryPolygon", "sourceSpatialReference": { "wkid": 26915,
