LineageRepresents three water level measurements collected in summer and fall of 1992 and spring of 1993. It includes field-measured elevations in domestic and observation wells and field-measured elevations of the major rivers in the study area. The purpose was to establish a potentiometric surface for the deeper regional ground-water system, establish a water table elevation map, and provide information of regional and local ground-water flow in the study area.

The Excel file was converted to an ARC/INFO point coverage using the following method:

  • Two comma separated value files were created, one with only the following three fields: the unique number and x and y coordinates, the other with all fields
  • In ARC, the 'generate' command converted the first comma separated value file into a simple point coverage.
  • In INFO, a data file was created from the second comma separated value file, the one containing all fields..
  • The ARC command, 'joinitem' connected the point coverage with the INFO data file, using the unique number as the relate id.
