EOS_GD_DUPREGION

EOS_GD_DUPREGION

This function copies the information stored in a current region or period to a new region or period and generates a new id. It is useful when the user wishes to further subset a region (period) in multiple ways.

Examples


In this example, we first subset a grid with EOS_GD_DEFBOXREGION, duplicate the region creating a new region ID, regionID2, and then perform two different vertical subsets of these (identical) geographic subset regions:

regionID = EOS_GD_DEFBOXREGION(gridID, cornerlon, cornerlat)
regionID2 = EOS_GD_DUPREGION(regionID)
regionID = EOS_GD_DEFVRTREGION(gridID, regionID, "Pressure",$ 
   rangePres)
regionID2 = EOS_GD_DEFVRTREGION(gridID, regionID2, $
   "Temperature", rangeTemp)

Syntax


Result = EOS_GD_DUPREGION(regionID)

Return Value


Returns new region or period ID or FAIL (–1) if the region cannot be duplicated.

Arguments


regionID

Region or period id (long) returned by EOS_GD_DEFBOXREGION or EOS_GD_DEFVRTREGION.
