## Section 2: Data Quality

Attribute Accuracy: 1:100,000
Logical Consistency: Data are topologically correct using ArcGIS 10.6
Completeness: Complete
Horizontal Positional Accuracy: File was snapped to statewide 30 meter LiDAR data.
Vertical Positional Accuracy: NA
Lineage: These files were made with water level information from two general sources: driller's logs from the County Well Index (CWI) database managed by the Minnesota Department of Health and the Minnesota Geological Survey with verified locations and measurements by DNR staff in conjunction with well sampling for this atlas project. The driller's log data represent a dataset that was collected over a period of several decades and spans seasonal and multi-year climatic trends of wet and dry conditions. Where the dataset included both CWI driller's log information and water levels collected by DNR staff, the DNR data were used.
Static water elevation data from CWI and DNR project data as described above for each particular aquifer were posted on individual maps with elevation data from major rivers as a reference. These data were contoured with the Topo to Raster tool (no drainage enforcement) to produce an elevation raster per aquifer unit. The analysis mask was set to the extent of the buried aquifer.

Field Name | Valid Values | Definition | Definition Source
--- | --- | --- | ---
AQUIFER_Q | - | Quaternary aquifer name, usually mapped at county scale. Quaternary aquifers are named after buried sand and gravel units shown on Plate 4, Part A. Bedrock aquifers are represented by "bdrk". |
CONTOUR | - | Elevation of potentiometric surface contour of the buried sand and gravel and bedrock aquifers in feet |
LN_TYPE | enumerated | Potentiometric contours are attributed as dashed or solid lines to communicate uncertainty and association with mapped sand aquifers. |
| Solid | Portion of contour that overlies mapped aquifer polygons. |
| Dashed | Portion of contour between mapped aquifer polygons, displayed for visual continuity and to help the map user understand the overall flow patterns. |
