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. ArcCatalog adds hints indicating which FGDC elements are mandatory; these are shown with gray text.

Description:
Abstract:
Desert Tortoise habitat categories as described by the 1988 Range-wide Desert Tortoise Plan.  This called for BLM offices to identify desert tortoise habitat categories.

Purpose:
For regional analysis and display at 1:24,000.  This dataset was prepared/acquired for use in the ASDO resource management planning process.

Supplemental information:
Dataset locally known as dtort_cat.  This dataset and other datasets in the Arizona Strip District Office Geographic Information Database (ASDOGID) represent data for the BLM Arizona Strip District Office, and may include the Arizona Strip Field Office, Vermilion Cliffs National Monument (VCNM) and/or the Grand Canyon-Parashant National Monument (GCPNM or PARA).  The Grand Canyon-Parashant National Monument is managed jointly by the BLM and the National Park Service (NPS).
The category designation for the area was based significantly on personal knowledge and manageability of the land.

Access constraints: Discretionary, contains no sensitive information - generally considered releasable.
Use constraints:
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 ASDOGID datasets or to imply that any changes made were approved by BLM ASDO or NPS.

No warranty is made by the BLM/NPS for use of the data for purposes not intended by BLM/NPS.  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:
This dataset covers the entire BLM Arizona Strip District.  It is constantly being reviewed and added to as additional information becomes available.

Positional accuracy:
Horizontal positional accuracy:
Horizontal positional accuracy report:
The data has been vertically integrated to the Arizona BLM Geographic Coordinate Database (GCDB) and to 1:24,000 scale DLG base data, including transportation, hydrology, and powerlines where appropriate.  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.

Process description:
In 1991, standard USGS maps were used to identify areas below 3,600 feet.  Then, these areas were categorized based on population data, vegetation, and known habitat conditions.  Specific habitat categories were identified based on the categorization data.  In 1993, the boundaries were adjusted based on personal knowledge and ground conditions.
