GridSplineSmooth2

GridSplineSmooth2 smooths an existing grid by interpolating new points with a cubic spline. Returns a Boolean. Returns 'True', if the operation is successful, otherwise, returns 'False'.

Syntax

object.GridSplineSmooth2( InGrid, nRow, nCol, Method, OutGrid, OutFmt, OutGridOptions )

Parameter	Type	Required/ Optional	Default	Description
InGrid	String	Required		This provides the path and file name of the input grid file.
nRow	Integer	Required		This specifies the number of nodes to insert between rows (Method=srfSplineInsert) or number of rows (
nCol	Integer	Required		This specifies the number of nodes to insert between columns (Method=srfSplineInsert) or number of columns(
Method	SrfSplineMethod	Optional	srfSplineInsert	This specifies the method either insert nodes or recalculate grid.
OutGrid	String	Optional	""	This provides the path and file name of the output grid file.
OutFmt	SrfGridFormat	Optional	srfGridFmtS7	This provides the output grid file format.
OurGridOptions	String	Optional	""	This provides the output option string for the grid format.

Example 1

This example demonstrates how to smooth demogrid.grd by doubling the number of rows and quadrupling the number of columns, saving the result as dgrid1.grd.

SurferApp.GridSplineSmooth2(InGrid:=SurferApp.Path+\Samples

nRow:=2, nCol:=4, Method:=srfSplineInsert, _

OutGrid:="c:\temp\dgrid1.grd", OutFmt:=srfGridFmtS7)

Example 2

This example smoothes diablo.grd with new points interpolated with a cubic spine and saves the spatial reference as an Esri World file.

Surfer.GridSplineSmooth2(InGrid:=InGridPath+"diablo.grd", nRow:=3, nCol:=2, OutGrid:=OutGridPath + "SplineSmooth.grd", OutFmt:=srfGridFmtS7, OutGridOptions:="UseDefaults=1, ForgetOptions=1, SaveRefInfoAsESRIWorld=1")
