Data Quality  

SCOPE OF QUALITY INFORMATION

DATA QUALITY REPORT - COMPLETENESS OMISSION    
MEASURE DESCRIPTION In conducting the mapping, the author(s) evaluated hundreds of water well records, especially those having relatively complete information on well location, static water level, well depth, ground elevation, and lithology. There were areas in the county with sparse information because of lack of well records or incomplete records.
 
DATA QUALITY REPORT - QUANTITATIVE ATTRIBUTE ACCURACY    
MEASURE DESCRIPTION The mapping was conducted after a thorough documentation of well locations and water well record details.
 
DATA QUALITY REPORT - ABSOLUTE EXTERNAL POSITIONAL ACCURACY    
DIMENSION horizontal
MEASURE DESCRIPTION The locations of many wells were field checked and the locations posted on 7.5 minute topographic maps. Visual confirmation of wells was not always possible. Many locations were based only on the street address, driving directions, or other location information provided on the well record.

Lineage  
PROCESS STEP    
WHEN THE PROCESS OCCURRED 2012-04-01T00:00:00 
DESCRIPTION The hand-drawn work maps (scale 1:24,000) showing lines of equal potentiometric surface elevation were digitized and edge matched in ESRI ArcEdit (ArcScan) by Scott H. Dean. The maps were individually georeferenced using a minimum of 4 tics per map. Projection was UTM, Zone 16, NAD83.

PROCESS STEP    
WHEN THE PROCESS OCCURRED 2012-04-01T00:00:00 
DESCRIPTION After the maps were joined, a polyline coverage was created and attributed by Scott H. Dean. Attribute definitions are described below.

PROCESS STEP    
WHEN THE PROCESS OCCURRED 2012-04-01T00:00:00 
DESCRIPTION After selection of water well records was complete, specific well data and other maps and reports were considered in the mapping process. For example, ground elevation, static water level, well depth, aquifer top and bottom elevation and lithology were obtained from well records. Other maps and reports included regional potentiometric surface elevations, hydrogeologic settings, ground-water availability, bedrock topography, and surface topography.
