Abstract:

Juan Bautista de Anza National Historic Trail Corridor

Purpose:

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

Supplemental information:

One of the three categories of national trails defined in the national Trails System Act of 1968 that can only be established by act of Congress and are administered by Federal agencies, although part or all of thier land base may be owned and managed by others.  national historic trails are generally more than 100 miles long and follow as closely as possible and practicable the original trails or routes of travel of national historic significance.  Thier purpose is identifying and protecting the historic route and its remnants and artifacts for public use and enjoyment.

REQUIRED: The basis on which the time period of content information is determined.

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 PDOGID datasets or to imply that any changes made were approved by BLM PDO.



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.

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 Phoenix District.  It is constantly being reviewed and added to as additional information becomes available.

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.
