Data Quality and Accuracy Information
General
Information about the fidelity of relationships, data quality and accuracy tests, omissions, selection criteria, generalization, and definitions used to derive the data.
Logical consistency report:
Geologic map data used in compilation was visually compared to original for omissions, line quality or other errors. No duplicates lines. Relationship classes we constructed in ArcGIS to link attributes of geologic objects to various tables for informational and query purposes. Use  schema diagram ("Digital Geologic Map Data Model V3.1xx: ESRI Geodatabase Schema Diagram" available at www.idahogeology.org) to get a overview of data linking possibilities. In ArcGIS 9.2 or greater users can use the identify tool to highlight a geologic object (line, polygon, or point) drill down the data hierarchy to discover information about the object.
Completeness report:
Geologic features and their attributes are assign by mapping geologists (see "sources" table in this data set)  Data presented here represent the best known current geology.
Attribute Accuracy
Accuracy of the identification of data entities, features and assignment of attribute values.
Attribute accuracy report:
Geologic map data are visually checked against original map data for completeness. Accuracy is determined by at least two factors: quality of capture (digitizing) consistency and the quality of the original geology. The quality of the original geology is by far the most important for determining the quality of attribute accuracy
Positional Accuracy
Accuracy of the positional aspects of the data.
Horizontal accuracy report:
Horizontal accuracy is difficult to quantify in geologic mapping of this type. User should use original map scale (linked to source table in this data set  via "source_ID) to determine relative accuracy of groups of map objects in the data set. ---EXAMPLE OF DETERMINING H ACCURACY:  1:24k map objects in the data set have a placement h-accuracy => 80(+/-) feet (.04 inch x 2000 ft/inch @1:24,000)  for a CONTINUOUS line type. Accuracy is proportionally less for smaller scales and even less for other line types (see linetype table for comparison via link on "Linetype" item). Map data used in compilation was visually compared to original for horizontal accuracy.

Metadata Standards
Description of the metadata standard used to document the data and reference to any additional extended profiles to the standard used by the metadata producer.
Standard name: FGDC Content Standards for Digital Geospatial Metadata
Standard version: FGDC-STD-001-1998
Time convention: local time
FGDC Plus Metadata Stylesheet
Stylesheet: FGDC Plus Stylesheet
File name: FGDC Plus.xsl
Version: 2.0
Description: This metadata is displayed using the FGDC Plus Stylesheet, which is an XSL template that can be used with ArcGIS software to display metadata. It displays metadata elements defined in the Content Standard for Digital Geospatial Metadata (CSDGM) - aka FGDC Standard, the ESRI Profile of CSDGM, the Biological Data Profile of CSDGM, and the Shoreline Data Profile of CSDGM. CSDGM is the US Federal Metadata standard. The Federal Geographic Data Committee originally adopted the CSDGM in 1994 and revised it in 1998. According to Executive Order 12096 all Federal agencies are ordered to use this standard to document geospatial data created as of January, 1995. The standard is often referred to as the FGDC Metadata Standard and has been implemented beyond the federal level with State and local governments adopting the metadata standard as well. The Biological Data Profile broadens the application of the CSDGM so that it is more easily applied to biological data that are not explicitly geographic (laboratory results, field notes, specimen collections, research reports) but can be associated with a geographic location. Includes taxonomical vocabulary. The Shoreline Data Profile addresses variability in the definition and mapping of shorelines by providing a standardized set of terms and data elements required to support metadata for shoreline and coastal data sets. The FGDC Plus Stylesheet includes the Dublin Core Metadata Element Set. It supports W3C DOM compatible browsers such as IE7, IE6, Netscape 7, and Mozilla Firefox. It is in the public domain and may be freely used, modified, and redistributed. It is provided "AS-IS" without warranty or technical support.
Instructions: On the top of the page, click on the title of the dataset to toggle opening and closing of all metadata content sections or click section links listed horizontally below the title to open individual sections. Click on a section name (e.g. Description) to open and close section content. Within a section, click on a item name (Status, Key Words, etc.) to open and close individual content items. By default, the Citation information within the Description section is always open for display.
