Abstract:
  These data were formerly available from the Montana State Library web site but were removed because they are potentially out of date. Please contact the Federal Superfund Bureau of the Montana Department of Environmental Quality if you want these data so they may tell you if newer or better data are available. If the data are not available from the Department of Environmental Quality, you may request a copy from the Montana State Library data archive.
  Hydrography arcs and points from 1:24,000 scale U.S. Geological Survey quadrangles, Upper Clark Fork Basin, Montana.
  The quadrangles have been joined into a single data set, but have not been edgematched. The USGS major and minor attribute codes have been replaced with the codes shown in this metadata record.
  See http://docs.msl.mt.gov/geoinfo/images/metadata/superfund/ClarkFork24kIndex1989.gif for dates of the source quadrangles.

Data Quality Information:

Attribute accuracy report:
  Attributes were interpreted from the original DLG files by a computer program. The accuracy of this interpretation has not been extensively checked. Attribute accuracy of the original Digital Line Graph data is estimated by the USGS at 98.5 percent, and was tested by them as follows:
  - manual comparison of the source with hard copy plots.
  - symbolized display of the digital line graph on an interactive compter graphic system.
  - Selected attributes that could not be visually verified on plots or on screen, were interactively queried and verified on screen.
  In addition, U.S. Geological Survey (USGS) Production System (PROSYS) software tested the attributes against a master set of valid attributes for the category; it also checked for selected valid attribute combinations, and for valid attributes relative to topology and dimensionality. All attribute data conform to the attribute codes current as of the date of digitizing.
Completeness report:
  The coverage only contains point and node attributes for the 13 quadrangles that were imported in 1997.
  For DLG data, Digital Revision Status = Not revised:
  Data completeness reflects the content of the source quadrangle. Features may have been eliminated or generalized on the source graphic, due to scale and legibility constraints.
  For DLG data, Digital Revision Status = Limited Update:
  This file has undergone limited update digital revision. The file contains only (1) those features that are photoidentifiable on monoscopic source, supplemented with limited ancillary source, and (2) those features, present on the original source quadrangle, that can not be reliably photoidentified but that are not considered particularly prone to change.
  For DLG data, Digital Revision Status = Standard Update:
  This file has undergone standard update digital revision. The data completeness of this file meets National Mapping Division standards for feature content.
Horizontal Positional Accuracy Report:
  Approximate accuracy is 12 meters, assuming the source maps meet National Map Accuracy Standards (NMAS). NMAS horizontal accuracy requires that at least 90 percent of points tested are within 0.02 inches of the true position.
  The digital data are estimated to contain a horizontal positional error of less than or equal to 0.003 inches standard error in the two component directions relative to the source quadrangle. Comparison to the graphic source is used as control to assess digital positional accuracy.
  Cartographic offsets may be present on the graphic source, due to scale and legibility constraints. Digital map elements require edge alignment between data sets. Data along each quadrangle edge are tested against the data set for the adjacent quadrangle using PROSYS; tests check for positional accuracy between data sets within a 0.02 inches tolerance. Features with like dimensionality, and with or without like attribution, that are within the tolerance are adjusted by moving the feature equally in both data sets. Features outside the tolerance are not moved.
