# GempakRadarHdrRequest
|
|
#
|
|
# This code has been developed by the SIB for use in the AWIPS2 system.
|
|
# Performs a BaseRequest for a radar "image header" from GEMPAK.
|
|
#
|
|
# Usage:
|
|
# import GempakRadarHdrRequest
|
|
# dataRequest = GempakRadarHdrRequest.GempakRadarHdrRequest()
|
|
# dataRequest.setPhysicalElement("...")
|
|
# dataRequest.setSectorID("...")
|
|
# dataRequest.setTime("...")
|
|
# return dataRequest.execute()
