  Description:
    Abstract: This vector point database is a compilation of state-wide drill holes contained in the North Carolina Geological Survey Repository of core, cuttings and geophysical logs.  The count as of 08/03/07 is 875.  These holes are from oil and gas exploration attempts, stratigraphic tests, municipal, domestic and industrial water wells, and mineral exploration efforts.  The fields used are described in the document - Field_Key.txt.
    Purpose: To make available a searchable listing of drill holes in North Carolina that have been archived by the North Carolina Geological Survey and have samples and or geophysical logs.

  Overview_Description:
    Entity_and_Attribute_Overview: The Detail_GM attribute contains geomorphic features mapped for target scale of 1:24,000.  Gen_GM contains generalized geomorphic units into which the Detail_GM features were grouped and would be appropriate at scales significantly smaller than 1:24,000.  Map_area indicates the project map area in which the entity occurs (Bodie Island, Pea Island, Rodanthe, Avon, Buxton or Ocracoke).
