Forty years of geologic investigations at the Nevada Test Site (NTS)
have been digitized. These data include all geologic information that:
(1) has been collected, and
(2) can be represented on a map within the map borders at the map
scale is included in the map digital coverages.
The following coverages are included with this dataset:
Coverage Type Description
------------------------------------------
geolpoly Polygon Geologic outcrops
geolflts line Fault traces
geolatts Point Bedding attitudes, etc.
geolcald line Caldera boundaries
geollins line Interpreted lineaments
geolmeta line Metamorphic gradients
These coverages are attributed with numeric values and interpreted
information. The entity files documented below show the data associated
with each coverage.
/* Procedures_Used
The original digital data came from the SCITEX scan used to print the
first NTS geologic map. More detailed information was compiled from
unpublished digital geologic data at a scale of 1:24,000 and generalized
for presentation at 1:100,000. Digital data was compiled from aerial
photography annotated with field geologic data. Further data was
supplied from unpublished geologic map information in many forms.
/* Revisions
This is Revision 3 of this data set. See references for previous revisions.
/* Reviews_Applied_to_Data:
The geologic data content has been reviewed by geologists of the
National Cooperative Geologic Mapping Program and the data structures
by GIS specialists also of the National Cooperative Geologic Mapping
Program.
/* Related_Spatial_and_Tabular_Data_Sets:
The following coverages are related to the main database and are
included with the database. Other than the descriptions below, these
data are not attributed.
