Title: Aggregate Resource Mapping Program - Status Map
Abstract: This spatial dataset is a status map of the Aggregate Resource Mapping Program's completed, in-progress, and requested projects, including links to project webpages and data downloads. This data was completed for a compilation of GIS aggregate resources (sand and gravel, crushed stone) reconnaissance scale data spanning twenty-seven county projects completed over a number of years (1987-present) by the DNR's Aggregate Resource Mapping Program (ARMP) and also the Minnesota Geological Survey (MGS).
Purpose: To display the status of completed, in-progress, and requested Aggregate Resource Mappnig Program projects including links to project webpages and data downloads.
About the Aggregate Resource Mapping Program:
The 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 out side 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.

Field Name | Valid Values | Definition | Definition Source

|  | Minnesota Department of Transportation database called Aggregate Source Information Systems. If the location did intersect a gravel pit, the locations were interpreted off of existing gravel pit sheets to relocate the mines to as specified on the sheet. This was ranked highest because of associated quality and texture data. Some locations were modified to better correlate to present gravel pit boundaries and on top of USGS 7.5 Minute Topographic Map symbols. |
| Topographic Map | These gravel pits are located from USGS 7.5 minute quadrangles. This was ranked second highest because of the widespread use of the maps. Where field checked, some of these pit types were changed from gravel to borrow or sand pits to reflect the material excavated. |
| Field Work | These pits were located while in the field. These pits were ranked third highest due to the fact they were directly observed for quality, texture, and spatial accuracy. |
| Soil Survey | The records for these pits are from the Soil Survey Geographic Database (SSURGO) Aitkin County. The dataset was downloaded in June 2010. These pits were ranked fourth highest. |
| Air Photo | Gravel mines were also located and some attributes were interpreted with air photography. These pits were ranked last because they were remotely interpreted. |
| LiDAR | LiDAR is giving an opportunity to see disturbed surfaces like never before. This is a new source. |
Status | enumerated | Mapping status |
| Completed | Completed by either the Aggregate Resource Mapping Program or the Minnesota Geological Survey |
| In Progress | Currently in progress by the Aggregate Resource Mapping Program |
| Not Requested | Not requested to be mapped for aggregate resources |
| Requested | Requested by a County Board Resolution to be mapped by the Aggregate Resource Mapping Program |
