ISpatialReferenceFactory.CreateProjectedCoordinateSystem Method

Creates a predefined projected coordinate system.

[Visual Basic .NET]
Public Function CreateProjectedCoordinateSystem ( _
    ByVal pcsType As Integer _
) As IProjectedCoordinateSystem
public IProjectedCoordinateSystem CreateProjectedCoordinateSystem (
    int pcsType
HRESULT CreateProjectedCoordinateSystem(
  long pcsType,
  IProjectedCoordinateSystem** pcs


pcsType   pcsType is a parameter of type long pcs [out, retval]

  pcs is a parameter of type IProjectedCoordinateSystem

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.


Use an element from the esriSRProjCSType, esriSRProjCS2Type, esriSRProjCS3Type, or esriSRProjCS4Type enumerations as the pcsType to create a particular predefined projected coordinate system.
