An Object-oriented Framework For Local Extensions To The WFO-ADVANCED Forecaster Display Workstation, D2d


The Forecast Systems Laboratory (FSL) has been engaged in the development and testing of a series of prototype workstations for use in the modernized National Weather Service (NWS) forecast offices. The central element of the latest system, WFO-Advanced, is the two-dimensional forecaster workstation known as D2D (MacDonald and Wakefield, 1996). Using a new capability in the D2D system, an extension framework, local forecasters and programmers in NWS offices can develop their own extensions to the display system. The extension framework is an object-oriented interface that makes local extensions possible. Such extensions could enable D2D users to display special kinds of data, interactively locate information in geographic databases, compute storm directions, and more. This paper describes the D2D extension framework, compares it to other types of frameworks, and discusses its future directions.
