ABSTRACT

Cartographic display of cross-scale phenomena and user-centered design are considered through a discussion of the development of an interactive web map depicting local-to-national economic impacts of hurricane storm surge events in Galveston Bay, Texas. Map development and design (as informed by stakeholder focus groups) is described, including approaches to presenting complex, cross-scale impacts of surge events across multiple years and scenarios. Particular consideration is given to how designs may communicate complexity without overly taxing users’ mental and perceptual resources (measured via NASA task-load index) or outstripping their mapping/domain expertise. The map produced uses linked map views to communicate multiple, cross-scale storm surge impacts. The production process and associated user testing highlighted the importance of matching tool complexity to users’ needs and levels of expertise, including through the use of tiered interface design. Optimizing the design of such maps to meet users’ needs is essential to fostering public hazard literacy.

摘要

通过讨论描述德克萨斯州加尔维斯顿湾飓风风暴潮事件对当地到国家经济影响的交互式网络地图的开发，考虑了跨尺度现象的制图显示和以用户为中心的设计。描述了地图开发和设计（由利益相关者焦点小组提供信息），包括呈现跨多年和情景的浪涌事件复杂、跨规模影响的方法。特别考虑了设计如何在不过度消耗用户的心理和感知资源（通过 NASA 任务负载指数测量）或超出他们的映射/领域专业知识的情况下传达复杂性。生成的地图使用链接的地图视图来传达多个跨尺度的风暴潮影响。生产过程和相关的用户测试强调了将工具的复杂性与用户的需求和专业水平相匹配的重要性，包括通过使用分层界面设计。优化此类地图的设计以满足用户的需求对于培养公共危害素养至关重要。
