Description:
Abstract: Point locations with characteristics of mines and prospects.
Purpose:
Digitizing this previously published information was prompted by the need for information to support the development of forest management plans by the U.S. Forest Service. But the recovery in digital form of printed information of this nature is a key goal of the mineral occurrence database project of the USGS.

Data_Set_Credit:
Painstaking digitizing and digital entry of these data was carried out by E. G. Boyce of the USGS, with technical assistance from Kelly Habestroh of the USGS library. Rearrangement of the digital information for distribution through web services and download, as well as composition of the metadata, was carried out by Peter Schweitzer of USGS.

Data_Quality_Information:
Logical_Consistency_Report:
It should be noted that more than one mine or prospect may be associated with each map location on the plates. The location numbers are not distinct between map sheets, so in these data the map_number field was adjusted by adding the plate number multiplied by 1000 to each original map number. So map_number values between 2000 and 2999 are located on plate 2, values between 3000 and 3999 are located on plate 3, and so on.

The maps depicted on the plates did not differentiate feature types graphically. Feature types specified in the feature field of the points table are taken from the feature name, and points shown without numbers are presumed to be unnamed prospects.

The map scales of the plates vary. Plates 3 and 6, which show the largest number of features, are mapped at 1:62,500, while plates 2,4, and 5 are mapped at 1:250,000. The consequence of this difference is that we should expect the geographic locations to be more precise if they were plotted on plates 3 or 6 than if they were plotted on plates 2.4. or 5.

The printed text contains numerous instances of words hyphenated across lines. A few of these have been corrected, but some likely remain in the descriptive fields.

Mines and prospect names that appear in parentheses in the report and spreadsheet are separated into Other Names in the shapefiles attribute tables.
Completeness_Report:
Users should note that this information is not a substantive update of the locations or characteristics of these mineral deposits or operations. The report was published by USGS in 1968 and it is likely that changes in the working status of mines and prospects have occurred since then, and it may be that new deposits have been located which were not known to the author of the 1968 report at the time.

The subject dataset was created by digitizing this previously published work.
Process_Step:
Process_Description:
The paper plates and printed reports of USGS Professional Paper 577 were scanned at high resolution. The plates contain maps at 1:62,500 (3 and 6) and 1:250,000 (2, 4, and 5) scale; these were geographically registered and the points digitized using ArcGIS 10.3. Table 4 of the report was converted to digital form using Dragon voice recognition software with the exception of the remarks field, whose contents were obtained by optical character recognition software. The text of the report (pages 1-17) was scanned at high resolution and subject to optical character recognition as well; the result is provided as a PDF document whose text may be selected or searched.

Process_Step:
Process_Description:
Digital copies of the data for each plate (as shapefiles) and for each part of table 4 (as Microsoft Excel documents) were converted to SQL code for entry into the PostgreSQL relational database using PostGIS geographic extensions.

Point and descriptive table row identifiers were disambiguated by including the plate number in each ID field. Where tabular information were listed as coming from plate "5 or 6" the records were matched manually using the names of the sites to assign correct ID values.

A number of simple corrections were made to name fields and other data fields to remove extraneous punctuation, carriage returns, and to establish one-to-one relationships between corresponding rows in the points and descriptions tables.

For each record, an XML and a JSON representation of the complete data record was created so that this information can be flexibly re-expressed in the future using appropriate technology (at this writing, 2016, reports of individual sites are composed by transforming the XML representation of the data into HTML using an XSLT stylesheet).

A geospatial map service was configured to provide these data to the public in the form of an Open Geospatial Consortium Web Map Specification service. The data are provided in an interactive web map interface using this service.

This metadata record was written to provide detailed documentation of the history of this data conversion effort.
