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 1:100,000.  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. 1:100,000 or smaller), and cartographic purposes.  The data is not suitable for analysis at scales larger than 1:100,000.

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.

Quantitative attribute accuracy assessment:
Attribute accuracy value: 100%
Attribute accuracy explanation:
Attributes were taken from source documents

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

Completeness report:
The dataset is considered complete for utility corridors in the Lake Havasu Field Office Resource Management Plan (2007).

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.

Quantitative horizontal positional accuracy assessment:
Horizontal positional accuracy value: unknown

Process step:
Process description:
A line layer was screen digitized from a scanned georeferenced Yuma RMP map.  The lines were buffered based on the width described in the RMP to produce the corridors.  The same process was used for utility corridor line data received from KFO which was clipped to the LHFO DRMP map boundary.  A similar process was used for the Lower Gila North and South (Phoenix) corridors except that the line data had to be constructed based on text in the planning documents using ROW data to aid in construction.  The bufferred data was then merged to create the utilcorridorsAlt1 layer.

Overview description:
Entity and attribute overview:
Attribute items are in typical ArcInfo point, line and polygon format.

Entity and attribute detail citation:
The BufferDist field shows the buffer distance used to create the corridors which is half the width of the proposed corridor in miles.  The Label field is used for map labels.  The Name field shows the name associated with the corridor.  Dec_Doc is the name of the decision document that approved the corridor.  Restrict identifies any restrictions to the approved corridor.
