摘要：Communication of natural hazard assessment results is crucial to protect people and infrastructure from devastating impacts of extremeevents. While hazard maps provide important information on potential impacts, their interpretation and the general knowledge exchangebetween stakeholders is often difficult. Web-based information systems contain the potential to support hazard management tasks by fastdistribution and customization of hazard visualizations through interactive functionality. However, cartographic principles are oftenignored in existing web-based visualizations which leads to poor graphical results and consequently to an impairment of the informationflow. While these issues need to be solved, a new task is already waiting: the integration of uncertainty information into hazardvisualizations. Since many hazard management activities rely on hazard assessment results, communication of associated uncertaintiesamong experts is vital.The challenge of this research is to overcome these existing shortcomings by combining high quality cartographic visualizations ofnatural hazard data as well as associated uncertainties with interactive functionality. The resulting web-based cartographic informationsystem will convene the needs of natural hazard specialists by offering a high level of customization: the suggested visualizations includevarious cartographic techniques such as the application of textures, bars, and interpolated surfaces. The possibility to interactively selectparticular data sets, customize colors, choose dimensions, query attribute data, and include uncertainty information facilitates theinterpretation of complex data and finally the communication among natural hazard specialists
