## 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: The groundwater flow elevations were created using static water-level data (for surficial and buried sand units) from: the County Well Index (CWI) database managed by the Minnesota Department of Health and the Minnesota Geological Survey, measurements by DNR staff in conjunction with well sampling for this atlas project, and river elevation points every 5 kilometers along the Mississippi River. The CWI records represent various climatic and seasonal conditions from 1949 through 2016. This data variability creates some uncertainty in groundwater elevations. Where the dataset included both CWI driller's log information and water levels collected by DNR staff, the DNR data were used. River elevation points are included because the Mississippi River is a major groundwater discharge location for the majority of the county. These data were contoured with the Topo to Raster tool (no drainage enforcement) to produce an elevation raster.
