  Description:
    Abstract:
      This data set includes cities in the United States
      including
      Puerto Rico and the U.S. Virgin Islands. These cities were
      collected from the 1970 National Atlas of the United
      States.
      Where applicable, U.S. Census Bureau codes for named
      populated places were associated with each name to allow
      additional information to be attached. The Geographic
      Names Information System (GNIS) was also used as a source
      for additional information. This is a revised version of
      the February 2000 data set.
    Purpose:
      This data set provides information needed to implement
      Title IV Abandoned Mine Reclamation, of the Surface Mining
      Control and Reclamation Act (SMCRA) of 1977. One of the
      major uses of this data set is for the reporting of annual
      Abandoned Mine Land Program accomplishments to Congress.
      In addition, the data is used in the National Atlas of the
      United States to create electronic and hard copy maps that
      depict various aspects of the nation. The data can be used
      to conduct geographic analysis on national and large
      regional scales. The digital data will provide a basis
      from which future revisions of the atlas can be derived.
    Supplemental_Information:
      The geographical information in the Abandoned Mines Land
      Inventory System (AMLIS) is a point representing each
      Problem Area. For many Problem Areas the point is the
      latitude and longitude of the southeast corner of the USGS
      quadrangle in which the Problem Area is located. For
      others is the center of the Problem Area. For the latest
      information on Problems Areas, see the AMLIS system at:

DATA_QUALITY_INFORMATION

  Attribute_Accuracy:
    Attribute_Accuracy_Report:
  Logical_Consistency_Report:
    The data set was checked for topological consistency using
    the Arc/INFO command BUILD. No other checks for logical
    consistency were performed on this data set.
  Completeness_Report:
    Not all coal related problems are included inthe inventory.
    In most cases, States and Indian tribes are responsible for
    finding problems and entering them into the Abandoned Mine
    Land (AML) Inventory. Some have chosen not to inventory all
    their problems, especially if they have a great many
    problems
    already in the inventory. Also, not all damage to lands and
    water by past coal mining qualifies for inclusion in the
    inventory. To be included as high priority, problems must
    pose a threat to human health, safety, or welfare.

      Attribute_Label: Display
      Attribute_Definition:
        A value used to specify whether a place name text label
        will be shown at the most detailed display scale in the
        National Atlas map browser.  It is determined by a ratio 
        based on population size and distance to nearest town and 
        was set by the following steps:
        1. Distance to the nearest neighbor was calculated for each 
        populated place.
        2. Population density was calculated by adding the 1990
        population values for each county and then dividing the 
        total by the area of the county. The 1990 population values
        of -99999 were set to 1.
        3. A display ratio was calculated using the formula 
        1990 Population x Distance / Population Density.
        4. Display was set to 1 for all points with a minimum 
        result of 15000, and set to 0 for the remainder of points.
