For regional analysis and display at 1:24000. This data set was prepared/acquired for use in the PFO resource management planning process.
Ground condition-Publication data
This data should never be used at a scale larger than 1:24000. The data and corresponding attributes are only as accurate as the source maps from which they were obtained, and may vary depending upon the date and method of acquisition. This data is suitable for regional planning, management decision support at intermediate scales, i.e. 1:24000 or smaller, and cartographic purposes. The data is not suitable for the purposes of navigation. This data is not suitable for analysis at scales larger than 1:24000. 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 PFO data sets nor to imply that any changes made were approved by BLM. No warranty is made by the BLM for use of the data for purposes not intended by BLM.

Feature attributes were taken from source material. Assignments are believed to be representative of the source document.
Chain-node topology present. Data was reviewed for correct topological structure. Duplicate lines have been removed and all linework has been edgematched at quadrangle boundaries.
Point, line, or polygon features and attributes are complete for the 75 7.5 minute quadrangles that cover the Phoenix Field Office Add more info if necessary & delete this sentence.
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 throughout editing. Horizontal positional accuracy for the digital data set was tested by visual comparison of the source data with hard copy.
Not Applicable - Lines and attributes.
Aquired for Phoenix. Digitized using USGS 7.5 minute quad as source maps on ADS in 1992. Converted to arc exports and covers than mosaic together.
