Public understanding of risk and the potential impact and damages from storm surge is based upon information that is communicated mostly through two-dimensional (2D) maps from emergency managers and the media. An NSF-funded project, Communicating Hazard Information in Modern Information Environment (CHIME), aimed to improve hazardous weather risk communication through the use of state-of-the-art technology for communicating storm surge risk and impacts. We developed 2D maps based on cartographic best practices, informational graphics, and, three-dimensional (3D) realistic landscapes to test public perception of individual risk to storm surge. The 2D maps were developed at three specific scales (regions, city level, and neighborhood level). These three scales showed the same storm surge information but with differing levels of detail for the GIS based data. The 3D visualization was an animation showing the landscape being flooded due to storm surge and conveyed the impact from this type of event. This project investigated the use of these types of technologies and products and how innovative approaches to communicating risk can help the public make an educated decision in the face of an approaching storm. This presentation will summarize key aspects of this project and in particular the process, workflow, and lessons learned from the development of the 2D and 3D geospatial visuals.
