GIS Lookup: Detailed Data Layer Listing

Data Layer GraphicTitle: "Geology - North Carolina (1:250,000)" (2007)
 
Description: 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. The geologic formation id is the only attribute present. There are two additional files which accompany this layer, dikes and faults. These should be used together with the Geology formations layer. All three files come together. (Refer to the cross references section for more detail on the dikes and faults). This data was created to assist governmental agencies and others in making resource management decisions through use of a Geographic Information System (GIS).

Use the ESRI layer file = geol250_polygons_92.lyr for proper symbolization as depicted on the published 1985 map; link to field 'GEOCODE'.

A README file (txt) describes 2007 attribute updates and the "age_ref.dbf" file that is also available for download from the /NCOM200911 folder linked below.
