GRIB_GETDATA

GRIB_GETDATA

The GRIB_GETDATA function returns the key/value pairs associated with a requested record in the form of an ORDEREDHASH.

Examples


In this example, we locate a GRIB file and ask IDL to return the 2nd record.

file = FILEPATH('atl.grb2',SUBDIRECTORY=['examples','data'])
data = GRIB_GETDATA(file, 2)
 

IDL returns:

help, data
DATA            ORDEREDHASH  <ID=1  NELEMENTS=224>

Syntax


Result = GRIB_GETDATA( filename, record)

Return Value


Returns an ORDEREDHASH of the requested record. The ORDEREDHASH contains all of the keys present in the record.

Arguments


FILENAME

A string denoting the name of the GRIB file for which IDL will return a record.

RECORD

The number of the record in the GRIB file IDL will return.
