Blueprint for Realtime Victim Tracking and Tracing

Functionality to

• read data from tags (barcode, RFID) of disaster victims (displaced/injured/deceased persons)
• submit actual location and status information on the particular victim to the Sahana database
• make location and status information available through person-related modules (DVR, DVI)
• render locations and status information on maps

Tracking System

Model

• Store different positions and position-related additional data (e.g. speed, course, ...) of objects/object groups related to time (points/intervals)
• Allow definition of object groups/subgroups and categories/subcategories
• Distinguish between first, past, current and forecasted positions

View

• Display tracks of positions of objects or object groups over a (user-defined) time interval
• Plot traces between positions
• Use certain indicators for additional data (such as speed or course) to mark (selected) positions
• Link additional information from the markers, e.g. free text, wiki-text, URLs

Controller

• CRUD functions for objects and groups/categories (RESTlike?)

• Take up real-time position data of objects from external sources and update the database
• Allow data transmission on multiple/parallel ways, e.g. HTTP, SMS, E-Mail, ...more?
• Transmission should be as easy, available, reliable and energy-efficient as possible
• Use derived/inherited data to minimize data transfer

• Forecast object positions (and other object features)
• Allow splitting of objects/groups into subdivisions

Other clients (e.g. on mobile devices)

• Capture real-time position data (and other information) of objects and send them to the server
• Allow data transfer on multiple ways (even in parallel)
