McFaul, G.T. Mason Jr., W.B. Ferguson, and B.R. Lipin, USGS Digital Data Series DDS-52" were converted to shape file format and projected to UTM, zone 11, NAD27 coordinates. This dataset, called "Nv_mils" and containing 7,700 records, was then exported from shape file format to a standard dBaseIII+ format for non graphic applications and use in other GIS type systems. Purpose: To make available USBM MAS/MILS summary digital data on various mine sites located in Nevada. Supplemental_Information: All data manipulations were performed to a standard that maintained the location accuracy of the initial data, i.e., the accuracy of MRDS and MILS data. Therefore the location of data points is only as good as the accuracy and completeness of the original digital data supplied by the U.S. Geological Survey and U.S. Bureau of Mines. In some cases the location information in these databases is of very poor resolution but in most cases the data are sufficiently accurate to convey the needed information for this project. Furthermore, very few records have available information for every field in a record.

DATA_QUALITY_INFORMATION

Attribute_Accuracy: Attribute_Accuracy_Report: All attributes created during the creation process were verified by displaying the points in both the database and the spatial coverage, but no formal tests were performed. Logical_Consistency_Report: These data are believed to be logically consistent, though no tests were performed. Completeness_Report: Data file contains those data points available from identified references at the time of project. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Approximate positional accuracy identified for each point in Pop field (meters). Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Approximate positional accuracy identified for each point in Elp field (meters).
