Description:
Abstract:
The North Carolina Department of Environment, Health, and
Natural Resources, Division of Land Resources, NC Geological
Survey, in cooperation with the North Carolina Center for
Geographic Information and Analysis, developed the GIS data set
version of the Geology of North Carolina.  The data represents
the digital equivalent of the official State Geology map (1:500,000-scale),
but was digitized from (1:250,000-scale) base maps.  This file
contains the line attributes which identify dikes in North Carolina.
The geologic formation id is the only attribute present.  There
are two additional files which accompany this layer, formations and faults.
These should be used together with the dikes layer. All three files come
together. (Refer to the cross references section for more detail on
the formations and faults).
Purpose:
This data was created to assist governmental agencies and
others in making resource management decisions through use of
a Geographic Information System (GIS).
Supplemental_Information:
This data includes three coverages: geol250, which contains
geologic formations; geol250d, which contains dikes; and
geol250f, which contains faults.

To purchase a hardcopy of this data layer (the official 1985
NC State Geologic Map, shown at a 1:500,000 scale), contact:

(919) 733-2423
As of December, 1995, map cost is approximately $10.00.

This coverage corresponds to the DOT county boundary file.
Other county boundary files may not be compatible with this
layer.

>cleaned and built based on coverage needs.  Raster data was
>projected using ESRI's Grid module and various steps as applicable.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
NCCGIA digitized the geology features and dikes
from mylar stable bases identifying boundary and name attributes of
geologic features.  A review by check plot overlay was used to determine
label discrepancies and found discrepancies were corrected.
Logical_Consistency_Report:
Using ESRI's ARC/INFO GIS software, the
dataset was built for arc topology using the "build" command.
The data set was then cleaned with a fuzzy tolerance of 1 foot.  Topology
has not been edited since the last build or clean.
Completeness_Report:
These data represent dikes found on the official geologic map
of North Carolina.  The information consists of three coverages, which
depict the state's geologic formations, its faults, and its dikes. Only
geology formation names are attributed.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
No official accuracy assessment has be performed on this data
set. The digital files were checked to within a linewidth of
the original base maps.  The base maps were delineated with
geologic extents identified by the U.S. Geological Survey and
the NC Geologic Survey.
