Simultaneous Visualization of Different Utility Networks for Disaster Management

Abstract

ABSTRACT:Cartographic visualizations of crises are used to create a Common Operational Picture (COP) and enforce Situational Awareness by presenting and representing relevant information. As nearly all crises affect geospatial entities, geo-data representations have to support location-specific decision-making throughout the crises. Since, Operator's attention span and their working memory are limiting factors for the process of getting and interpreting information; the cartographic presentation has to support individuals in coordinating their activities and with handling highly dynamic situations. The Situational Awareness of operators in conjunction with a COP are key aspects of the decision making process and essential for coming to appropriate decisions. Utility networks are one of the most complex and most needed systems within a city. The visualization of utility infrastructure in crisis situations is addressed in this paper. The paper will provide a conceptual approach on how to simplify, aggregate, and visualize multiple utility networks and their components to meet the requirements of the decision-making process and to support Situational Awareness.

Generalized Cartographic and Simultaneous Representation of Utility Networks for Decision-Support Systems and Crisis Management in Urban Environments

“…Each range encodes unique and dedicated information (MacEachren, 2004;MacEachren et al, 2005), within this information process chain. Thus, a new cartographic design schema and related design rules have to be developed to simplify the visualization radically, while preserving as much information as needed (Semm et al, 2012). Having a user-centered design in mind cognitive psychology plays a key role, since complex information has to be visually processed.…”

“…In today's technologically advanced society the dependency of every citizen and company on having a working infrastructure is extremely high [Semm et al, 2012]. Therefore, precise and comprehensive knowledge about 3D urban space, with above and below-ground features, is required for simulation and analyses.…”
