NAME

natgrid_params - This document briefly describes all the internal parameters of Natgrid.

DESCRIPTION

'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.
