Group: Summary
  Aeromagnetic surveys are used for geophysical prospecting.  Some
  variations in magnetic measurements are caused by rocks that
  contain significant amounts of magnetic minerals (magnetite being
  the most common).  These anomalies reflect variations in the
  amount and type of magnetic material and the shape and depth of
  the body of rock.
  Aeromagnetic anomaly maps are important tools in mapping
  surficial and buried igneous rocks.  The features and patterns
  of aeromagnetic anomalies can also be used to delineate details
  of subsurface geology including the locations of buried faults and
  the thickness of surficial sedimentary rocks.
  
  Aeromagnetic data were collected along flight lines by instruments in an
  aircraft that recorded magnetic-field values and locations.  This dataset
  presents latitude, longitude, altitude, and magnetic-field values.
  
  The U.S. Geological Survey has contracted or flown numerous
  airborne surveys over a long period (1950's to present).  Not
  all flight-line data have been released to the public
  because of lack of personnel to reformat data and service the
  requests.  With the improvement in digital communication
  and the ability to store and transmit large data sets, the
  USGS is now able to release the flight-line data in a
  common format.
  
  A companion CD-ROM/web site has been released containing
  magnetic data that were generated by digitizing analog maps.
  Digital flight-line data used to create the analog maps are
  unavailable.  Reference is in the Cross-Reference section of
  this metadata file.
