# GempakRadarImgLinkRequest
|
|
#
|
|
# This code has been developed by the SIB for use in the AWIPS2 system.
|
|
# Performs a BaseRequest for a radar image from GEMPAK, and stores
|
|
# the image data in the uEngineProducts directory for later transfer.
|
|
#
|
|
# Usage:
|
|
# import GempakRadarImgLinkRequest
|
|
# dataRequest = GempakRadarImgLinkRequest.GempakRadarImgLinkRequest()
|
|
# dataRequest.setProduct("...")
|
|
# dataRequest.setIcao("...")
|
|
# dataRequest.setResolution("...")
|
|
# dataRequest.setAngle("...")
|
|
# dataRequest.setTime("...")
|
|
# return dataRequest.execute()
