natgrid_params (3NCARG)

Each entry below includes the name of a parameter, its Fortran type (use the obvious equivalents for C), its default value, and a short description of the parameter.

\'ADF\' - Integer - 0

Flags if the data file of algorithmic information for display with nnalg is produced - see parameter alg (0=no; 1=yes).

\'ALG\' - Character - \'nnalg.dat\'

File name for input to the algorithmic display tool nnalg (see parameter adf).

\'ASC\' - Integer - 1

Flags if automatic scaling is allowed (0 = no; 1 = yes).

\'bI\' - Real - 1.5

Tautness factor that increases the effect of the gradient estimates as bI increases.

\'bJ\' - Real - 7.0

Tautness factor that decreases the breadth of the region affected by the gradient estimates as bJ increases.

\'EXT\' - Integer - 1

Flags whether extrapolation is allowed outside the convex hull (0=no; 1=yes).

\'HOR\' - Real - 0.1*(extent of X output grid)

Specifies the amount of horizontal overlap to be included outside of the current region when doing subblocking.

\'IGR\' - Integer - 0

Flag indicating if gradient estimates are to be computed (1=yes; 0=no).

\'MAGX\' - Real - 1.0

Scale factor for X coordinate input values.

\'MAGY\' - Real - 1.0

Scale factor for Y coordinate input values.

\'MAGZ\' - Real - 1.0

Scale factor for Z coordinate input values.

\'MDM\' - Integer - 10

Maximum number of informational messages about duplicate point culls.

\'NON\' - Integer - 0

Flags whether interpolated values are allowed to be negative (0=yes; 1=no).

\'NUL\' - Real - 0.0

The value to be used on output for points outside of the convex hull when extrapolation is not allowed.

\'RAD\' - Integer - 0

Flags if slopes and aspects are returned in radians or degrees (1=radians;0=degrees).

\'SDI\' - Integer - 0

Flags if slopes and aspects are computed (0=no; 1=yes).

\'UPD\' - Integer - 1

Flags if the output array goes from south to north or north to south (0=north to south; 1=south to north).

\'VER\' - Real - 0.1*(extent of Y output grid)

Specifies the amount of vertical overlap to be included outside of the current region when doing subblocking.

\'XAS\' - Real - 1.0

Contains the scale value for automatic scaling of X input values in the most recent interpolation call. For retrieval only.

\'YAS\' - Real - 1.0

Contains the scale value for automatic scaling of Y input values in the most recent interpolation call. For retrieval only.

\'ZAS\' - Real - 1.0

Contains the scale value for automatic scaling of Z input values in the most recent interpolation call. For retrieval only.
