This infographic employs open data to examine potential impacts of the Saint John flood plain on designated evacuation routes and fire station service zones.

Gaps in open data suggest the need open data sources that could improve analysis of and real time responses to flooding events.

Objectives

Visualize the extents of potential flooding in Saint John, New Brunswick. Visualize specific risks due to this flooding. Visualize combinatorial risks due to this flooding. Identify opportunities to improve monitoring and response to flooding using open data sources in the City of Saint John's Open Data Catalogue.

Risk :- “effect of uncertainty on objectives.”

“Risk is often expressed in terms of a combination of the consequences of an event (including changes in circumstances) and the associated likelihood [...] of occurrence.”

Combinatorial Risk :- a risk that arises only through the combination of multiple risks.
