Coordinate system: Universal Transverse Mercator

Theme keywords: tortoise, desert tortoise, BLM, Bureau of Land Management, biota, Wildlife

Abstract: Digitized vector data of Desert Tortoise (gopherus agassizii suitable habitat in BLM Lake Havasu Field Office, Arizona and California. Digitized from 1:100,000 scale manuscripts prepared by Field Office Wildlife Specialists or digitized on-screen and edited at 1:100,000 scale or larger by GIS specialists. The criteria used included elevation, terrain, climate and vegetation.

FGDC and ESRI Metadata:

Metadata elements shown with blue text are defined in the Federal Geographic Data Committee's (FGDC) Content Standard for Digital Geospatial Metadata (CSDGM). Elements shown with green text are defined in the ESRI Profile of the CSDGM. Elements shown with a green asterisk (*) will be automatically updated by ArcCatalog.

Access constraints: None. This is considered public information
Use constraints:
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.

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

Completeness report:
Data currently considered complete.

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.
