Description:

Abstract:: This report publishes a geologic digital spatial database (NVGEO) for the geologic map of Nevada by Stewart and Carlson (1978a) which was originally printed on a single sheet of paper at a scale of 1:500,000 (and later reprinted on two sheets in 1991). The spatial digital database (GIS) provided in this report supersedes earlier digital editions by Turner and Bawiec (1991) and Raines and others (1996).
Purpose:: This digital spatial database is one of many being created by the U.S. Geological Survey as an ongoing effort to provide geologic information for use in spatial analysis in a geographic information system (GIS). This database can be queried in many ways to produce a variety of geologic maps. This database is not meant to be used or displayed at any scale larger than 1:500,000 (for example, 1:100,000).
Supplemental_Information:: The digital geologic map of Nevada consists of a single spatial database (NVGEO) which contains map units and lines. The feature attribute tables include a geologic linework table, NVGEO.AAT, that relates to the NVGEO.CON (contacts and boundaries), NVGEO.ST2 (structures), and NVGEO.REF (source reference) files, and a rock unit table, NVGEO.PAT, that relates to the NVGEO.RU (rock unit) and NVGEO.REF (source reference) files.

Data_Set_Credit:

An initial digital edition of the Stewart and Carlson (1978a) geologic map of Nevada was prepared by Turner and Bawiec (1991). Raines and others (1996) revised and updated Turner and Bawiec's (1991) first edition. This third digital edition, prepared by Robert J. Miller with assistance from Steve Ludington and Barry C. Moring, represents further revision of Raines and others' (1996) second edition.

Native_Data_Set_Environment:

Microsoft Windows 2000 Version 5.0 (Build 2195) Service Pack 4; ESRI ArcCatalog 8.3.0.800

Data_Quality_Information:

Logical_Consistency_Report:

Polygon and chain-node topology present. Segments making up the outer and inner boundaries of a polygon tie end-to-end to completely enclose the area. Line segments are a set of sequentially numbered coordinate pairs. No duplicate features exist nor duplicate points in a data string. Intersecting lines are separated into individual line segments at the point of intersection. All nodes are represented by a single coordinate pair, which indicates the beginning or end of a line segment.

Completeness_Report:

All geologic units were compiled from Stewart and Carlson (1978a) at a scale of 1:500,000.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Registration and/or transformation errors for the original digitizing are not available.

Quantitative_Horizontal_Positional_Accuracy_Assessment:

Horizontal_Positional_Accuracy_Value: 200- 500 meters
Horizontal_Positional_Accuracy_Explanation:: Based on comparison of the topographically sensitive linework (i.e., Quaternary sediments in narrow valleys, etc.) with larger scale topographic basemaps.

Process_Step:

Process_Description:: Geologic map was digitized from mylar publication materials and minimally attributed.
Source_Used_Citation_Abbreviation: Stewart and Carlson, 1978a
Process_Date: Unknown
Source_Produced_Citation_Abbreviation: Turner and Bawiec, 1991

Process_Step:

Process_Description:: Katherine A. Connors joined the north and south halves of the first edition of the GIS (Turner and Bawiec, 1991), edited labels, and deleted multiple labels. She added nonprinting lines (where nvlntype = 0) to manage (or take into account) ArcInfo and plotter limitations. And, she selected arcs with same formation on both sides (these should be most of the faults) and calculated nvlntype = 6. Gary L. Raines examined all thrust faults and formation labels on the paper map (Stewart and Carlson, 1978a) and made corrections to the first edition of the GIS (Turner and Bawiec, 1991). He selected and flipped all incorrectly oriented fault arcs, and he added labels for formations to polygons without labels. In all, he edited and corrected over 6,000 fault orientation and formation label errors.

Process_Step:

Process_Description:: Robert J. Miller rubbersheeted the boundary (perimeter) of the State of Nevada (in ESRI ArcInfo coverage format) to match a reference dataset of state boundaries derived from 1:100,000-scale digital line graphs (DLG). He replaced the section of the state boundary which follows the Colorado River with a line from 1:100,000-scale DLG hydrographic files. He updated the metadata to Federal Geographic Data Committee (FGDC) compliance. Steve Ludington designed a table for lithologic information (based on the Digital Geologic Map Data Model, version 4.3 by Johnson and others (1998), and he populated the table with information derived from the description of map units by Stewart and Carlson (1978b) and various other sources. Robert J. Miller attached Ludington's table of lithologic information to the spatial database (ArcInfo GIS). Barry Moring systematically proofed the resultant geologic map database (GIS) against a scanned image of the paper geologic map by Stewart and Carlson (1978a): he made numerous corrections to the GIS with regards to polygon labels, arc attributes, and arc locations, in addition to incorporating hydrologic features.
