Elevation Method

The method used to verify the location's elevation. The following methods are used:

 

Altimeter

elevation determined by digital Surveyor's altimeter from a known reference elevation on a topographic map or from a known elevation at an existing well

 

Hand Level

elevation determined by hand level from a known elevation on a topographic map or at another existing well

 

None

determining the elevation was not possible, thus no method was used

 

Paulin

elevation determined by a Paulin Surveyor's altimeter from a known reference elevation on a topographic map or from a known elevation at an existing well

 

Topo Map

indicates one of two possibilities based on past practices of the IGS:

 

  1. If the well site was actually visited, Topo Map means that the elevation visually appeared correct when compared to a topographic map (for example, in an area of flat topography), but no instruments were used confirm the elevation.

  2. If the well location was reviewed in the office, but not visited, the location is consistent with the elevation indicated by a topographic map. In such cases, the value for Field Check Status in the main Well Header is entered as "Reviewed."
