EOS_SW_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.

Syntax

Result = EOS_SW_DUPREGION(regionID)

Return Value

Returns new region or period ID or FAIL (–1) on error.

Arguments

regionID

Region or period id (long) returned by EOS_SW_DEFBOXREGION, EOS_SW_DEFTIMEPERIOD, or EOS_SW_DEFVRTREGION.

Keywords

None

Examples

In this example, we first subset a swath with EOS_SW_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_SW_DEFBOXREGION(swathID, cornerlon, $  
   cornerlat, 0)  
regionID2 = EOS_SW_DUPREGION(regionID)  
regionID = EOS_SW_DEFVRTREGION(swathID, regionID, $  
   "Pressure", rangePres)  
regionID2 = EOS_SW_DEFVRTREGION(swathID, regionID2, $  
   "Temperature", rangeTemp)
