Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The accuracy of file data attributes is highly variable, especially for some parts of Africa and Asia. Most locations are believed to be within 5 minutes of the exact location; some locations are for the nearest town, and other locations may be highly inaccurate. Location errors are a result of inadequate or incorrect original data, error caused by multiple locations with the same name, and error introduced by data entry or location format conversion. Data were plotted at a preliminary stage to check that sites plotted in the correct country and the data tables were spot-checked (1 in 5 records) against the original data.
Logical_Consistency_Report:
Location is not given by coordinates for 448 of the 1635 reported sites.
Completeness_Report:
This report is the most complete compilation of phosphate mines, deposits, and occurrences known. However, it is highly likely that there are additional phosphate sites that are not included. In addition, data for many of the sites are incomplete. Determination of latitudes and longitudes for some sites were impossible given the available data.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The horizontal positional accuracy of the digital data was checked to be sure that they plotted within the correct country. The latitudes and longitudes were largely determined using latitude-longitudes given in one of the references or determined from descriptions of the location using the maps available to us or the GEOnet Names server on the National Imagery and Mapping Agency's NIMA database. The accuracy of these locations vary with the detail of the original information.

A consequence of these considerations is that no specific horizontal datum should be preferred for these data. Unfortunately modern GIS software requires that a datum be specified, so the WGS84 datum has been applied. However accuracy and precision of these locations does not warrant concern over the datum.

Entire source of data. Some minor spelling corrections, re-formatting, reduction of non-informative values, and explicit linking of reference information was carried out to create the version found on MRData.usgs.gov.
Process_Step:
Process_Description:
G.J. Orris and C.B. Chernoff compiled the data on world phosphate deposits from previously published compilations, new published sources, "gray" literature, company internet sites, and other sources. Locations were commonly taken from published sources, no effort was made to determine the correctness of these data beyond a preliminary review to be sure they plot in the correct country. Other locations were found using the GEOnet Names server on the National Imagery and Mapping Agency's website, www.nima.mil. Still other locations were determined using available maps of varying scales. Most of the latitudes-longitudes are believed to be within 5 minutes of their true locations, but other locations may be highly inaccurate due to inadequate or incorrect location data.
Process_Date: 2001
Process_Step:
Process_Description:
Reformatting of the data, rearranging into separate relational tables, explicit linking, where possible, of short references with bibliography entries, reduction of non-informative data values. For example, "Unknown" need not be spelled out because a NULL value carries this meaning.

OGC WMS, WFS, search, and data selection and download interfaces developed to enhance visibility and utility of these data.
