Many of us have watched in horror and sadness over the previous week as fires consumed much of the beautiful hills and parts of the towns of Napa and Sonoma Counties. Many of us know people who were evacuated with a few minutes' notice - I met a retired man who left his retirement home with the clothes on his back. Many other friends lost everything - house, car, pets. It was a terrible event - or series of events as there were many active fires. During those 8+ days all of us were glued to our screens searching for up-to-date and reliable information on where the fires were, and how they were spreading. This information came from reputable, reliable sources (such as NASA, or the USFS), from affected residents (from Twitter and other social media), and from businesses (like Planet, ESRI, and Digital Globe who were sometimes creating content and sometimes distilling existing content), and from the media (who were ofen using all of the above). As a spatial data scientist, I am always thinking about mapping, and the ways in which geospatial data and analysis plays an increasingly critical role in disaster notification, monitoring, and response. I am collecting information on the technological landscape of the various websites, media and social media, map products, data and imagery that played a role in announcing and monitoring the #TubbsFire, #SonomaFires and #NapaFires. I think a retrospective of how these tools, and in particular how the citizen science aspect of all of this, helped and hindered society will be useful.  

In the literature, the theoretical questions surrounding citizen science or volunteered geography revolve around:

• Accuracy – how accurate are these data? How do we evaluate them?  

• Access – Who has access to the data? Are their technological limits to dissemination?

• Bias (sampling issues)/Motivation (who contributes) are critical.

• Effectiveness – how effective are the sites? Some scholars have argued that VGI can be inhibiting. 

• Control - who controls the data, and how and why?

• Privacy - Are privacy concerns lessened post disaster?

I think I am most interested in the accuracy and effectiveness questions, but all of them are important.  If any of you want to talk more about this or have more resources to discuss, please email me: maggi@berkeley.edu, or Twitter @nmaggikelly.

Summary so far. This will be updated as I get more information.

Outreach from ANR About Fires

• ANR has a number of programs dedicated to fire preparedness, recovery, and prevention.

Core Geospatial Technology During Fires

• Wildfire products

  • Fire perimeters from https://www.geomac.gov/services.shtml

    • The Active Fire Perimeters layer is a product of Geospatial Multi-Agency Coordination (GeoMAC). In order to give fire managers near real-time information, fire perimeter data is updated daily based upon input from incident intelligence sources, GPS data, infrared (IR) imagery from fixed wing and satellite platforms.”

  • MODIS hot spots from USFS Active Fire Mapping Program. MODIS The MODIS instrument is on board NASA's Earth Observing System (EOS) Terra (EOS AM) and Aqua (EOS PM) satellites. In addition to lots of other data, MODIS delivers Channel 31 brightness temperature (in Kelvins) of a hotspot/active fire pixel.
