Frequently-anticipated questions:

What does this data set describe?
    Title: XYheat_prod
    Abstract:
    Heat Production is a measure of subsurface thermal activity, and is related to heat sources such as radioactive decay and mantle plumes. Values are in microwatts per cubic meter, with a typical range being between 0 and 8.
    Supplemental_Information:
    The original data file was imported from a raw text file into Microsoft Excel. Column headers were added based on previous metadata and information listed at the top of the file. The file was then exported as a database IV (.dbf) file for easy import into the ArcGIS suite. ArcCatalog was used to convert the data into a shapefile and add projection information. The heat flow data was then used to create an Inverse-Distance-Weighted raster of the values.

  6. How does the data set represent geographic features?

    1. How are geographic features stored in the data set?

      This is a Vector data set. It contains the following vector data types (SDTS terminology):

      • Entity point (422)

    2. What coordinate system is used to represent geographic features?

      Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.000001. Longitudes are given to the nearest 0.000001. Latitude and longitude values are specified in Decimal degrees.

      The horizontal datum used is North American Datum of 1927.
      The ellipsoid used is Clarke 1866.
      The semi-major axis of the ellipsoid used is 6378206.400000.
      The flattening of the ellipsoid used is 1/294.978698.
