GeoGraphVis: A Knowledge Graph and Geovisualization Empowered Cyberinfrastructure to Support Disaster Response and Humanitarian Aid

The past decade has witnessed an increasing frequency and intensity of disasters, from extreme weather, drought, wildfires to hurricanes, floods, wars. Providing timely disaster response humanitarian aid these events is a critical topic for decision makers relief experts in order mitigate impacts save lives. When occurs, it important acquire first-hand, real-time information about the potentially affected area, its infrastructure, people develop situational awareness plan address health needs population. This requires rapid assembly multi-source geospatial data that need be organized visualized way support disaster-relief efforts. In this paper, we introduce new cyberinfrastructure solution—GeoGraphVis—that empowered by knowledge graph technology advanced visualization enable intelligent making problem solving. There are three innovative features solution. First, location-aware created link integrate cross-domain make analytics-ready. Second, expert-driven workflows analyzed modeled as machine-understandable paths guide exploration via graph. Third, scene-based strategy developed interactive heuristic visual analytics better comprehend impact situations action plans aid.
