Digital Dashboards
• Most important management information needed to support strategic activities (Few, 2006;
Liang and Miranda, 2001)
• Single Screen
• Performance Indicators
• User-friendly
• Drill-down function (Vasiliu, 2006)
• Decision-making faster

Research Problem
• Brazil faces a lot of structural problems:
– Traditional performance indicators are not sufficient
– Real-time information is not easily available
– There is not a standard to connect the information system available
12

Research Problem
• Main research question
How to support the real-time decision-making in flood situations through the rivers monitoring?
13

AGORA-GeoDash
• Processes real-time information
• Enables the interoperability among other information systems (OGC standards)
• Provides performance indicators essentials for flood risk monitoring

AGORA-GeoDash
• The Hazard Index
– Uses depth and water velocity to identify if an adult can be dragged by the water (Rotava et al., 2013)

• Wireless Sensor Network with three sensors using ZigBee for the Data Source Layer
• Communication among sensors and base station via JSON

• The Service layer uses JSP to process and PostGIS to storage the data provided by the previous layer.
• The communication with the Visualization Layer uses SOS Specification specifically the 52 north framework (Jirka et al., 2012).

• Geosensor Dashboard • The Visualization Layer
uses ExtJS with OpenLayers framework to handle the geographic data and integrate with OGC services.

Evaluation
• Flood event on Oct 22-23, 2013
– 2h20m of rain with an amount of 105mm (all Dec)
22
Page 23
Evaluation
• Rainfall on Nov 4, 2013

Conclusion
• Real-time information is essential
• The AGORA-GeoDash presents itself as an important approach to support decision-making
• Hazard Index is an important performance indicator to aid in flood situations
24

Future Work
• Improve the dashboard with other performance indicators
• Integrate Volunteered Geographic Information (VGI) with other sources to provide real-time information (Degrossi & Albuquerque, 2014)
• Interface and usability analysis
