Description:

Abstract:

The NR_EXTENT spatial database contains a single polygon that identifies the areal or spatial extent of the NR_GEO geologic map spatial database.

Purpose:

NR_EXTENT provides a layer for use in a GIS to define the areal extent of the geologic map compilation represented by the NR_GEO spatial database. It is especially useful for when the user is viewing subsets of the data that may not cover the entire map area.

Supplemental_Information:

The NR_EXTENT spatial database covers an area that includes most of Idaho north of the Snake River Plain, the west half of Montana, and a narrow sliver of northeast Washington.

Use_Constraints:

The NR_EXTENT spatial database is meant to be used with the NR_GEO spatial database and any derivative files. NR_EXTENT is not meant to be used or displayed at any scale larger than 1:250,000 (for example, 1:100,000). Any hardcopies utilizing these datasets shall clearly indicate their source. If the user has modified the data in any way, they are obligated to describe the types of modifications they have performed on the hardcopy map. User specifically agrees not to misrepresent these data sets, nor imply that changes they made were approved by the U.S. Geological Survey.

Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 2; ESRI ArcCatalog 9.0.0.535

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

A visual comparison (onscreen) verified that the NR_EXTENT boundary (for the one and only polygon) matched the spatial extent of the outermost boundary of NR_GEO spatial database and was attributed in the polygon attribute table (NR_EXTENT polygon) as representing the NR_GEO spatial database.

Logical_Consistency_Report: Polygon topology present. No duplicate features.

Completeness_Report:

The NR_EXTENT spatial database portrays the entire geographic area represented by the NR_GEO spatial database.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

The horizontal positional accuracy of the NR_EXTENT spatial database is excellent.

Quantitative_Horizontal_Positional_Accuracy_Assessment:

Horizontal_Positional_Accuracy_Value: 0 meters

Horizontal_Positional_Accuracy_Explanation:

The polygon in the NR_EXTENT spatial database matches the outer spatial extent of the NR_GEO spatial database.
