This function reads data from the designated level fields into the data buffer from the subsetted area of interest.
Examples
In this example, we read data within the subsetted area of interest defined by EOS_PT_DEFBOXREGION from the Longitude and Latitude fields:
regionID = EOS_PT_DEFBOXREGION(pointID, [-145.,-135.], [-15.,-8.])
IF (regionID NE -1) THEN BEGIN
status = EOS_PT_EXTRACTREGION(pointID, regionID, 0, $
"Longitude,Latitude", buffer)
HDF_UNPACKDATA, buffer, dataLong,dataLat,HDF_TYPE=[6,6]
ENDIF
Syntax
Result = EOS_PT_EXTRACTREGION( pointID, regionID, level, fieldlist, buffer)
Return Value
Returns SUCCEED (0) if successful and FAIL (–1) otherwise.
Arguments

regionID
Period id (long) returned by EOS_PT_DEFBOXREGION.
level
Point level (0-based long).
