Description:
Abstract:
GIS dataset of the Extensive Recreational Management Areas (ERMAs) approved for the Lake Havasu Field Office RMP 2007.  These settings apply to BLM lands in Arizona and California within the Lake Havasu Field Office.

Purpose:
For regional analysis and display at 1:24,000.  This dataset was prepared to support decisions in the Lake Havasu Field Office Resource Management Plan.

Supplemental information:
Dataset locally known as LHFO_ERMA,shp.  This dataset and other datasets in the Lake Havasu Field Office Geographic Information Database represent data for the BLM Lake Havasu Field Office.

Access constraints: Discretionary, contains no sensitive information - generally considered releasable.
Use constraints:
This data should be used in conjunction with the Lake Havasu Field Office RMP of 2007.  This data should not be used at a scale larger than 1:24,000.  The data and corresponding attributes are only as accurate as the source maps from which they were obtained, and may vary depending on the data and method of acquisition.

This data is suitable for regional planning, management decision support at intermediate scales (i.e. 1:24,000 or smaller), and cartographic purposes.  The data is not suitable for analysis at scales larger than 1:24,000.

If the Receiving Agency (RA) has modified the data in any way, they are obligated to describe the types of modifications they have performed on hardcopy maps utilizing the data.  RA specifically agrees not to misrepresent LHFO datasets or to imply that any changes made were approved by BLM LHFO.

No warranty is made by the BLM for use of the data for purposes not intended by BLM.  This information may be updated without notification.

Data Quality Information:


Attribute accuracy:
Attribute accuracy report:
Feature attributes were taken from source material.  Code assignments are believed to be representative of the source document.

Logical consistency report:
Data was reviewed for correct topological structure.  Duplicate lines have been removed.

Completeness report:
Dataset is considered complete for the Extensive Recreational Management Areas in the LHFO RMP 2007.  It should be used along with the Special Recreational Management Areas to cover the field office.

Positional accuracy:
Horizontal positional accuracy:
Horizontal positional accuracy report:
Overall horizontal accuracy for this data is not greater than national mapping accuracy standards (NMAS) for USGS source maps.  Snapping and coordinate shift tolerances were maintained at 0.01 meters or less through editing.  Horizontal positional accuracy for the digital data set was tested by visual comparison of the source data with hard copy verification plots.
