IGIS and UCCE assess the spread of fire in Sonoma and Napa Counties

Reposted from the UC IGIS blog

Recently I was fortunate to work with the IGIS team in Santa Rosa and Sonoma to explore why so many homes and buildings were lost in the October Tubbs and Nuns Fires.  With the IGIS's Shane Feirer we collected drone-based video to record how the fires burned through the vegetation near and around the lost structures.

We observed several sites where there was little fire activity in the forests or woodlands, yet the homes burned.  This type of video helps us document how devastating a wind-driven ember fire can be and of the important lessons we can learn to be better prepared for wildfire.

From this experience I came away with a painful reminder that we all need to do a better job at focusing on fuels near our homes (e.g. combustible wood mulches used in landscaping, lawn furniture, leaf accumulations, dry landscape plants, etc.), especially in the 5 feet immediately adjacent to our homes. While the Tubbs Fire originated in grassy area in Calistoga it easily picked up embers from the burning vegetation which were moved by the 40-70 mph winds and created spot fires ahead of the flaming front. In short time these embers were blasted into homes via attic or soffit vents (critical to let moisture out of a building) or they ignited combustible materials close to buildings; these types of exposures are the primary way the Tubbs Fire started to consume homes. Eventually the Tubbs Fire moved to the more densely populated areas of the Fountain Grove subdivision in Santa Rosa and with each new home that was ignited a new source of embers were created. The embers that came from the burning buildings included 2 x 4s, chunks of wood the size of a frisbee, and other materials. These materials were blasted over Highway 101 on to homes and businesses in the urban center of Santa Rosa- a place most thought could not be impacted by wildfire. The winds persisted till mid-morning on October 9th providing considerable time for an ember to find a weakness in the home. All of us hope we never have a fire like this again, but as history shows us, California's most damaging fires typically occur in the September and October and are often wind-driven. 

For many years UC has worked in educating homeowners about fire preparedness in the Wildland Urban Interface (WUI). These fires have resulted in the largest number of structure losses to date in California and we all need tools to better understand how to learn from these experiences.  I greatly appreciate IGIS's willingness to help me collect some critical data in a time sensitive manner.

IGIS to hold three-day drone bootcamp in July 2017

Reposted from the IGIS blog

IGIS is pleased to announce a three-day "Dronecamp" to be held July 25-27, 2017, in Davis. This bootcamp style workshop will provide "A to Z" training in using drones for research and resource management, including photogrammetry and remote sensing, safety and regulations, mission planning, flight operations (including 1/2 day of hands-on practice), data processing, analysis, and visualization. The workshop content will help participants prepare for the FAA Part 107 Remote Pilot exam. Participants will also hear about the latest technology and trends from researchers and industry representatives.

Dronecamp builds upon a series of workshops that have been developed by IGIS and Sean Hogan starting in 2016. Through these workshops and our experiences with drone research, we've learned that the ability to use mid-range drones as scientifically robust data collection platforms requires a proficiency in a diverse set of skills and knowledge that exceeds what can be covered in a traditional workshop. Dronecamp aims to cover all the bases, helping participants make a great leap forward in their own drone programs.

Dronecamp is open to all but will have a focus on applications in agriculture and natural resources. No experience is necessary. We expect interest to exceed the number of seats, so all interested participants must fill in an application before they can register. Applications are due on April 15, 2017.
