Card 9 - FIELDOPTIONS

This optional card specifies the options supported from the interpolation methods in Card 9 - FIELDINTERP.

Parameters: KODE, T1, N1, N2

KODE

KODE is the code FIELDOPTIONS

T1

T1 is ID.

N1

N1 can be:

  • ALGORITHM is a keyword to specify the interpolation algorithm for the LINEAR method
  • APPROXRADIUS is a keyword for the search radius as a fraction of the diagonal used for the INVERSE method.
  • APPROXNUMBER is a keyword for the fraction of all points used for the INVERSE method.
  • APPROXTOLERANCE is a keyword for the nearest neighbor tolerance used for the ANEIGHBOR and INVERSE methods.
  • SHIFT is a keyword for the independent value shift for the LINEAR method.
  • DIVISOR is a keyword for the independent value divisor for the LINEAR method.
  • OUTSIDE

N2

N2 can be:

  • LINEAR_LINEAR (or LOG_LINEAR, LINEAR_LOG, or LOG_LOG) that is the interpolation algorithm used for the LINEAR method.
  • CONSTANT or UNDEFINED or EXTRAPOLATE for the treatment of points that lay OUTSIDE of the field independent variables ranges.
  • A number from 0 to 1 for APPROXRADIUS, APPROXNUMBER, and APPROXTOLERANCE.
  • Any real number for SHIFT and DIVISOR options specified above.
