SetInputGrids

SetInputGrids sets the input grids and coordinate system of a vector map.

Syntax

object.SetInputGrids( GridFileName1, GridFileName2, CoordSys, AngleSys, AngleUnits )

Parameter	Type	Required/ Optional	Default	Description
GridFileName1	String	Required		This provides the one-grid file name, or two-grid X component (angle) grid file name.
GridFileName2	String	Optional	""	This provides the two-grid Y component (length) grid file name.
CoordSys	SrfVecCoordSys	Optional	srfVecCartesian	This provides the two-grid vector map coordinate system.
AngleSys	SrfVecAngleSys	Optional	srfVecBearing	This provides the two-grid vector map angle system for polar coordinates.
AngleUnits	SrfVecAngleUnits	Optional	srfVecDegrees	This provides the two-grid vector map angle units for polar coordinates.

Remarks

The number of grids cannot be changed with this routine. If a vector map was created with two grids, it must remain a two-grid vector map.

Example

This example demonstrates how to specify new grid files for an existing vector map.

VectorLayer.SetInputGrids(GridFileName1:=SurferApp.Path+"\Samples\demogrid.grd")
