The above map, from the U.S. Forest Service’s excellent Wildland Fire Assessment System, shows the current Fire Danger Rating based on current and antecedent weather, fuel types, and both live and dead fuel moisture (the classes are explained here).
A group I follow, Understanding Risk, has posted a call for mapping assistance to support the typhoon Yolanda/Haiyan disaster relief efforts. They are recruiting volunteers to use OpenStreetMap to digitize roads, buildings, and other features from satellite imagery made freely available by Microsoft and the US State Department’s Humanitarian Information Unit. The resulting maps will be used by the Red Cross, the United Nations and other responding organizations working in the Philippines. To get started, you can:
The 5th International Conference of Crisis Mappers will be held 18-22 November 2013 in Nairobi, Kenya, and will bring together the most engaged practitioners, scholars, software developers and policymakers at the cutting edge of crisis mapping and humanitarian technology. ICCM 2013 follows successful conferences in 2009, 2010, 2011, & 2012. Register here.
The USDA Forest Service’s Active Fire Mapping Program uses satellite data and interagency information to provide detection and characterization of wildland fires across the United States and Canada. The program acquires temporal image data directly from NASA’s Moderate Resolution Imaging Spectroradiometer (MODIS) satellite for near real-time data coverage for the entire United States and Canada. This imagery is combined with fire intelligence information and GIS technologies to create a suite of geospatial products assessing current fire activity, fire intensity, burned area extent and smoke conditions throughout the U.S. and Canada. You can browse the results at the program’s extraordinary website as GIS datasets and live data services, multi-spectral image subsets, and analytical products/summaries.
And a note of great respect for those acting on this information on the ground, including nineteen members of the Granite Mountain Hotshots that died last week defending lives and property near Yarnell, AZ.
Drones – a.k.a. unmanned airborne vehicles (UAVs) – are poised for domestic use in disaster assessment. UAVs are portable, affordable aircraft that can launch quickly in dangerous situations and could be used to locate survivors or provide data on the impact of a disaster. Earlier this year, the American Red Cross in Oklahoma tested the use of UAV’s in assessing the extent of disasters but the Federal Aviation Administration (FAA) is very restrictive about who can fly a drone and how they can fly it within the United States. The FAA has committed to promulgating regulations by 2015 to govern the domestic U.S. use of UAVs, but in the meantime, disasters like the recent Oklahoma tornadoes will have to make do with satellite imagery.
“There’s a spectrum. On one end is mindless complacency. On the other is paranoia. The challenge is to find that place in the middle where you understand that bad things can happen, but it doesn’t consume your life.”
I have to confess a being more than a little dismayed when the author noted being surprised to hear Redlener say the authorities might not respond promptly in the event of a disaster – that everyone should be prepared to take care of themselves for several days. That is, in fact, part of the National Plan – that the entire community needs to take part in disaster preparedness and response. I guess theadvertisingcampaignhasn’tpaidoff…
Inauguration Day preparations have included adding temporary cell towers along the National Mall in an attempt to avoid the wireless traffic congestion witnessed during the 2009 inauguration. Event organizers have also mounted a public information campaign to encourage people to send text messages rather than call and to avoid watching streaming video of the event. As the infographic at left shows, an SMS text message requires much less data to send than, say, a picture or cellphone conversation. Emergency managers often see wireless traffic overwhelm cellular networks during large events, and this year’s inauguration will likely attract 2 million people.
A map of power outages as predicted by Guikema’s model based on the official National Hurricane Center track and intensity forecast from 18UTC (3 p.m. EDT) on Saturday, Oct. 27.
Johns Hopkins researcher Seth Guikema has used historical storm statistics to estimate that Hurricane Sandy will likely cause 10 million people to lose power, from Virginia Beach to New York City. Guikema’s model uses outage data from 11 hurricanes to estimate the fraction of customers who will lose power, based on expected gust wind speed, expected duration of strong winds greater than 20 meters per second, and population density.
