Community-engaged map and augmented reality tools for storm surge flooding: Prior work and new directions for coastal hazardscape communication
Storm surge flooding threatens hundreds of thousands of persons and billions of dollars in property in the Houston-Galveston metro area. In a series of studies, cartographic and augmented reality (AR) visualizations of storm surge hazard and impact zones in the Galveston Bay Area were developed and user-tested. Results from these studies are presented, with emphases on community-engaged design and how data management and design decisions (e.g., scale, data variable selection, level of aggregation, filtering, symbology, and perspective) can radically alter the shape and character of the hazard zone. While some quantitative results are presented, particular consideration is given to qualitative assessments of how such data and design decisions situate the hazard relative to the users of these map and AR-based tools.
