Metadata created using Minnesota Geographic Metadata Guidelines

Metadata Summary

Originator | Department of Natural Resources, Division of Lands and Minerals, Mineral Potential Section
Abstract | This dataset includes information gathered in the field. Fieldwork was completed in the fall of 2002 and spring of 2003. It includes approximately 950 field observation sites within Le Sueur County and contains a field description of each site, the dominant type of material encountered, the source of information, type of site, unit thickness, and overburden thickness.

Associated Data Sets | The County Aggregate Mapping Program dataset for Le Sueur County is included in the file lesudata.zip, accessible from the MN DNR Aggregate Mapping web page: http://www.dnr.state.mn.us/lands_minerals/aggregatemaps.html The dataset is also available as aggregate resource data layers stored at drive:\data\resource on the CD (where 'drive' is the CD reader or writer drive on the PC). The data layers include data on sand and gravel potential, crushed stone potential, field observations, rock piles, and test pit quality data.

Attribute Accuracy |
Logical Consistency |
Completeness | The data points were gathered at the location where field observations took place. Additional information is given in the Lineage section.
Horizontal Positional Accuracy | The differential correction of the GPS unit for GPS located sites is +/- 2 meters. Some point locations were located on a 1:24000 USGS topographic map.
Vertical Positional Accuracy | Not applicable.
Lineage | A GPS unit was used to determine some of the locations of the data points. These points were then downloaded and slightly revised based on field observations, topographic maps, and aerial photographs. The GPS unit (with differential correction) is accurate to approximately a few meters. Other points were located on 1:24000 USGS topographic maps and 1:40000 aerial photographs. These coordinates were then checked with field notes and topographic maps to assure accuracy.

Section 5 | Entity and Attribute Information | Top of full metadata | Top of page
Entity and Attribute Overview | This dataset consists of field observation site locations, type of site, unit thickness, and overburden thickness. ArcView specific fields include shape (i.e., feature type = point), area (0 for points), perimeter (0 for points), fieldobs_ (unique id for point, assigned by the software), fieldobs_id (an id usually assigned during theme creation).
