Storm Surge: Vancouver Case Study

Posted by in Geographical Information Systems

The Greater Vancouver area is developed on a delta which is susceptible to tide changes, specially if there is a sudden change in sea level.  Luckily Vancouver Island’s presence helps decrease the effects of tsunamis from seismic activity, but the area is still at risk of a storm surge.  With large amounts of datasets, I have learned to mine through the data and to represent them based on scenarios.  Below are a few maps of the Greater Vancouver area made in ArcMaps using the ArcGIS software.

Vancouver Template used for the maps.  Layer used represents areas susceptible and intensity for flooding.
