As they do after many major weather-related events around the world (such as Moore, Oklahoma last month), Google has just published a Crisis Response map for Alberta to help citizens deal with the incredible flooding.
You can view all of the data on the main Crisis Response map, or download specific KML files to view the data in Google Earth such as this road closure KML, seen here:
The map includes a wealth of information including the road closures seen above, river basin advisories, evacuation zones, shelters, traffic information, and much more. For anyone dealing directly with this situation, this data is invaluable.
The main crisis response page/map is being updated constantly, though you’re encouraged to check out the Recovery Information page from the Alberta Government for the latest official news from the province.
