Abstract | This dataset consists of information about the quality of Minnesota Department of Transportation's evaluated gravel pits and other aggregate sources. Quality information includes soundness, durability, and mineral content. This table contains the averages and ranges of values for the different quality tests and was summarized by the MN DNR from the Mn/DOT pit sheets. |

Ordering Instructions | The Aggregate Resource Mapping Program's spatial datasets for Carlton County and the Fond du Lac Reservation are included in the file carlton_aggregate_data.zip, accessible from the MN DNR Aggregate Mapping web page: http://www.dnr.state.mn.us/lands_minerals/aggregate_maps/completed/index.html The spatial datasets are also available as shapefiles and a file geodatabase stored at drive:\data\resource on the associated CD (where 'drive' is the CD reader or writer drive on the PC). The spatial datasets include: sand and gravel potential, crushed stone potential, field observations, mining pits, depleted mining lands, Minnesota Geological Survey (MGS) County Well Index (CWI) data points, sieve analysis table of selected field observations, MGS CWI stratigraphy table, and Mn/DOT ASIS pit quality table. Selected aggregate resource datasets from this project can also be viewed in the Aggregate Resource Mapping Program's Aggregate Mapper at: http://www.dnr.state.mn.us/lands_minerals/aggregate_maps/online_maps/index.html Aggregate Mapper allows users the ability to work with the aggregate resource data without having to download additional software. The site can display spatial and tabular aggregate resource data such as sand and gravel potential, crushed stone potential, field observations, mining pits, and depleted mining lands. This information can be overlaid on a variety of base map information from Web Mapping Services (WMS) sources like; 1:24,000-scale DRGs (digital topographic maps), 1991 black-and-white air photos, and 2008 Farm Service Agency color air photos. |

Title | Carlton County and Fond du Lac Reservation Aggregate Resource Evaluation - Mn/DOT Quality Database - carldotqual.dbf | |||
Abstract | This dataset consists of information about the quality of Minnesota Department of Transportation's evaluated gravel pits and other aggregate sources. Quality information includes soundness, durability, and mineral content. This table contains the averages and ranges of values for the different quality tests and was summarized by the MN DNR from the Mn/DOT pit sheets. | |||
Purpose | This table summarizes the quality data that is presented on the Mn/DOT pit sheets. Mn/DOT has specifications that the aggregate must meet to be used for specific jobs. This table summarizes the quality data by averaging the values of the pit and giving the range of values. The data can be joined to carlpits.shp using the 'ASIS_NUMBR' field. | |||

Associated Data Sets | The carlpit shapefile and the carlasis0108 shapefile can be joined to this table's field named 'asis_numbr' using the 'Asis_numbr' field or the 'Sourcenum' field as the primary key in the above mentioned shapefiles. The Aggregate Resource Mapping Program's spatial datasets for Carlton County and the Fond du Lac Reservation are included in the file carlton_aggregate_data.zip, accessible from the MN DNR Aggregate Mapping web page: http://www.dnr.state.mn.us/lands_minerals/aggregate_maps/completed/index.html The spatial datasets are also available as shapefiles and a file geodatabase stored at drive:\data\resource on the associated CD (where 'drive' is the CD reader or writer drive on the PC). The spatial datasets include: sand and gravel potential, crushed stone potential, field observations, mining pits, depleted mining lands, Minnesota Geological Survey (MGS) County Well Index (CWI) data points, sieve analysis table of selected field observations, MGS CWI stratigraphy table, and Mn/DOT ASIS pit quality table.

Section 2 | Data Quality Information | Top of full metadata | Top of page | |
Attribute Accuracy | The ranges of values were taken directly from the Mn/DOT pit sheets. These numbers were also averaged to represent the entire pit. However, a pit may meet specifications on one end and not the other, or the top 10 feet may meet specifications and the bottom layers do not. Thus, care must be taken when interpreting this information. For further detail, refer to the pit sheets from Mn/DOT. | |||

Completeness | All available data were summarized and are incorporated within this table. | |||

Lineage | The ranges of values were taken directly from the Mn/DOT pit sheets. These numbers were also averaged to represent the entire pit. However, a pit may meet specifications on one end and not the other, or the top 10 feet may meet specifications and the bottom layers do not. Thus, care must be taken when interpreting this information. For further detail, refer to the pit sheets from Mn/DOT. | |||

Entity and Attribute Overview | The ranges of values were taken directly from the Mn/DOT pit sheets. These numbers were also averaged to represent the entire pit. However, a pit may meet specifications on one end and not the other, or the top 10 feet may meet specifications and the bottom layers do not. Thus, care must be taken when interpreting this information. For further detail, refer to the pit sheets from Mn/DOT. The data in this table can be related to their spatial locations by using either the carlpits shapefile or the carlasis0108 shapefile. The primary key in carldotqual.dbf is the 'asis_numbr' field which can be related to the corresponding 'Asis_numbr' field in carlpits.shp or to the 'sourcenum' field in carlasis0108.shp. | |||
