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
