Data quality report - Quantitative attribute accuracy
Measure description
From Bluemle, JP, 1983: The most important source of information used in compiling this map was the test-hole data obtained during drilling by the North Dakota State Water Commission as part of a series of comprehensive groundwater studies of North Dakota. These studies have been underway since about 1960. Agencies cooperating in these studies have been the North Dakota Geologial Survey, North Dakota State WAter Commission, U.S. Geological Survey and The County Commission (or its equivalent). Additional geologic and topographic control for the map was obtained by the use of hte NDGS power auger; by study of exploratory oil well geophysical logs; by study of exploratory coal drilling data; and by examinations of exposures. In certain areas, assorted sources of data such as WPA well scedules, commercial water well driller's records, Minuteman missile site drilling data, and seismic information were utilized in compiling the map. The accurace of the map is dependant upon the density and reliability of the control points. The map is essentially precise in those parts of southwestern North Dakota where surface exposures are widespread and control is nearly continuous. The map is less precise in areas of thick glacial overburden, where only a few test holes have penetrated as deep as the bedrock surface.

Overview Description
Entity and Attribute Overview
Attributes are based on legend from original paper map.

Lithology is subdivided based on if the map unit specifies more than one formally named unit. Genesis1 corresponds to the origin of lith1, genesis2 with lith2, etc.  For example, The Golden Valley Formation has an upper and lower member.  The upper member is lith1, with its origins reported in genesis1.  The lower member lithology is in lith2, with its origin in genesis2.
