Thanks to a generous offer from a contact on the Google Crisis Response team, CalTopo is temporarily displaying high-resolution imagery for portions of the fire-affected areas in Napa and Sonoma counties. This imagery was taken by DigitalGlobe on Wed the 11th, and although the fires are still ongoing, it provides some degree of insight into what had burned by that point. While there is a lot of smoke present, in many areas it’s clear enough for a house-by-house assessment.
Because the original imagery is false-color infrared (which gives vegetation a strong red tint), I’m converting it to black-and-white to avoid any possible confusion between the red tint and currently burning areas. I’m told that true-color imagery will be available at some point on Fri, and hopefully I’ll be able to upgrade the layer to match.
