Interesting Stuff
These are some of the projects that I have worked on in the past.
Red River Flood Animation
This is an animation I created with ArcView 3.2 and the Spatial Analyst extension. It represents a modelled flood which would occur in the area south of Winnipeg along the Red River. This area floods every year so it was of particular interest to me. This scenario is what would happen if the Red River Floodway would not open to divert flood waters. At one point, the Floodway itself is inundated as water passes over the closed gates.
I modelled the flood with a script created by Bill Huber of Quantitative Decisions. I took screen-grabs of the flood at increasing elevations. Screen-grabs were created using Snag-it and I used Coffee-cup animator to create the animated gif file which simulates a flood in progress.Charlottetown Storm Surge Simulation - Part 1 - Part 2
This simulation was created for an internal exercise to test policy reactions to natural disasters. The two images show different versions of a storm surge caused by an Atlantic Ocean hurricane. The hurricane is wreaking havoc with the Northumberland Strait and sends a series of surges toward the coastal city of Charlottetown, Prince Edward Island.St John Storm Surge Simulation
This simulation was made in the same way as the Charlottetown simulation but the flooding was shown with an animation rather than a static map. Both the Charlottetown, Prince Edward Island and St John, New Brunswick floods were created using the ArcView Extension Floodarea. It is a German application (not free) that is excellent at simulating floods. It is able to simulate dam breaches, pipe bursts and rain storms, taking into account the size of the rain cloud and the rate of rainfall, which can change throughout the simulation. For the two storm surges I created, I performed an flood offshore and allowed it to rush toward land, simulating a a series of storm surges.Collegeville
The Emergency Preparedness College trains emergency preparedness officials and professionals. For the exercises that are performed there, locations are needed to make the situations realistic. For that purpose, the town of Collegeville was created. It is based upon Saskatoon of 1975. The problem is that data for 1975 is very hard to come by. To make the map, an older hard copy map of Saskatoon/Collegeville was used. The data was modified to remove all of the new developments until the digital data matched the previous version. This map may not be interesting but it took me 6 months to create the data and polish the map.
