Automatic post Santa Rosa fire damage assesment.
About the Map
In October 2017 the Tubbs Fire became one of the most destructive wildfires in the state of California’s History. In total the fire burned across 3 counties, requiring the evacuation of nearly 100,000 people. However, the city of Santa Rosa experienced the most devastation.
Previously, efforts to assess such damage would include individuals from the city government and insurance companies going neighborhood to neighborhood and verifying each site in person. With the help of a couple of cheap, unmodified, consumer drones Hivemapper was able to accomplish the same task in a fraction of the time.
Using Hivemapper’s machine vision technology post-fire video was compared directly to a pre-fire LiDAR scan of the area which allowed for all changes over 50 cm to be clearly identified.
This feature is often used for highlighting small changes such as vegetation growth or moved vehicles and machinery. In Santa Rosa, by setting Change Detection to only show changes greater 3 meters, it was used to quickly identify any major structures leveled by the fire.
|Santa Rosa||Impacted Objects|
|Single Family Homes Destroyed||595|
|Other Structures Destroyed||240|
