Abstract

An important component of Early Warning Systems (EWS) for man-made and natural hazards is the command and control unit’s Graphical User Interface (GUI). All relevant information of an EWS is concentrated in this GUI and offered to human operators. However, when designing the GUI, not only the user experience and the GUI’s screens are relevant, but also the frameworks and technologies that the GUI is built on and the implementation of the GUI itself are of great importance. Implementations differ based on their applications in different domains but the design and approaches to implement the GUIs of different EWS often show analogies. The design and development of such GUIs are performed repeatedly on some parts of the system for each EWS. Thus, the generic GUI framework of a geospatial EWS for tsunamis is introduced to enable possible synergistic effects on the development of other new related technology. The results presented here could be adopted and reused in other EWS for man-made and natural hazards.

Methodology

After providing the motivation for the presented results and the application of free and open source software (FOSS), the technological framework for a command and control unit’s GUI to be applied in each EWS for man-made and natural hazards is introduced with a simplified architecture for the Command and Control User Interface (CCUI) used in natural crisis management (NCM) for tsunamis developed in DEWS and TRIDEC. In this context, the selected GUI frameworks and geo frameworks are introduced together with an application oriented Geographic Information System (GIS) and the relevant standards and technologies.
