Fire forced the closure and evacuation of Jasper National Park this week, and the Jasper townsite itself was directly hit by flames on Wednesday. Parks Canada estimates about a third of the town’s structures have been destroyed. Municipal officials released a preliminary map today showing the damaged and destroyed buildings in the town. They stress that the information “is based on the damage that is visible from the street. We have not been inside buildings or seen the backside of properties. There may be additional damage to homes and businesses that isn’t visible from the street. Buildings marked as ‘not damaged’ on the map could also have internal damage caused by smoke and water. Consider this a preliminary description of properties affected in Jasper.” CBC News coverage.

Canada’s Early Wildfire Season
Another year, another map from the European Space Agency showing the extent of Canada’s wildfires based on data from the Copernicus Sentinel-5P satellite. It’s not nearly as bad as last year’s, but it’s way earlier. The above is a frame from an animated map showing carbon monoxide concentrations earlier this month. “The extremely high concentrations, depicted in dark shades of orange, can be linked to active fires during this time period.”

Two Ways to Visualize Canada’s Wildfires
The European Space Agency released this map showing the impact on atmospheric carbon monoxide from Canadian forest fires. “Using data from the Copernicus Sentinel-5P mission, the image shows the average concentration of carbon monoxide for 1 May to 13 June. The extremely high concentrations, which are depicted in deep tones of orange, can be linked to active fires during the time. The image also shows how this air pollutant was carried as far as New York in the USA and over the Atlantic.”
Also from the ESA: this animated map of fire outbreaks in Canada during the same period.

Fire and Smoke Forecast Maps
Last week my location was blanketed by smoke from forest fires in northern Quebec, with the air quality index pegged as high as it goes (which is to say, eleven). The iPhone’s default weather app has an air quality map that I made use of—you could actually see the fire hotspots—but there are other wildfire maps out there. For example: NOAA’s experimental interactive map based on its HRRR-Smoke model; AirNow’s Fire and Smoke Map; and the interactive smoke forecast from FireSmoke Canada. [Maps Mania]
Wildfires in Alberta
Here are some links to maps and satellite imagery of the wildfires devastating Alberta right now. The Alberta provincial government’s Alberta Wildfire Status Dashboard shows active wildfires and historical data; CBC News has produced four maps that distill and simplify data from that dashboard. NASA Earth Observatory has images of the wildfires from the Terra satellite’s MODIS instrument.
Wildfire Aware
Wildfire Aware is an interactive map of wildfires in the United States that lists fires by the number of personnel fighting them. Selecting a fire brings up a lot more information, drawn on 22 layers from Esri’s ArcGIS Living Atlas of the World. [ArcGIS Blog]
Google Maps Announcements
Google Maps updates this week: wildfires are getting their own dedicated layer in Google Maps; their tree canopy coverage tool is being expanded to 100 cities; and a new Address Maker app will make it possible to bulk-add Plus Codes to locations without addresses.
Mapping Climate Change’s Impact on California’s Fire Seasons
ProPublica maps the change in California’s fire seasons. “As California continues battling its worst wildfire season on record, new research shows that fall fire weather days—days with high temperatures, low humidity and high wind speeds—will double in parts of the state by the end of the century and will increase 40% by 2065. […] In the north, a summer fire season has been driven by high temperatures and low humidity. In Southern California, fall fire season is driven by east winds. With climate change, though, both the summer and fall fire seasons have grown longer, and are melting into each other, overlapping in time and space.” [Joshua Stevens]
California Wildfires: Mapping the Bigger Picture
Two maps:
John Nelson’s 100 Years of Wildfire is a static map showing a century of California wildfires, simplified into zones of 100 square miles. The map measures the cumulative burn area for each zone over that entire time: this can exceed 100 or even 200 percent if large fires are frequent enough, or the whole damn area burns down more than once.
The California Fire Observatory combines longer-term data about forest cover with up-to-date information about wildfire hotspots and wind speed. “We map the drivers of wildfire hazard across the state—including forest structure, weather, topography & infrastructure—from space. […] By providing these data for free we hope to support the development of data-driven land management strategies that increase wildfire resilience—for forests and communities—enabling people and nature to thrive.” [Maps Mania]
More on the Western U.S. Wildfires
NASA Earth Observatory has had several stories on the western U.S. wildfires, gathered here. This story summarizes the situation; satellite images of the smoke generated by the fires can be seen here, here and here.

Tracking Amazon Fires
Last year saw an uptick in fire activity in the Amazon basin. This year a new tool has been released that aims to help classify the fires being observed. The Amazon Dashboard classifies each fire as a deforestation fire, a savanna fire, a small clearing and agricultural fire, or an understory forest fire, and tracks whether the fire is in a protected or indigenous territory. NASA Earth Observatory:
The fire analysis tool is already bringing new clarity and insight to the 2020 fire season. In July, Brazil announced a 120-day ban on fires in the Amazon rainforest; it was presented as an effort to limit ecological damage from fires this year. However, the NASA-led fire analysis indicates that there has been a proliferation of fires in key deforestation hotspots in the southern Amazon states of Pará, Mato Grosso, and Amazonas.

Wildfire status tracking. The California Governor’s Office of Emergency Services posts a daily map showing the status of active wildfires in the state. It’s basically a one-page PDF you can print and hand out: decidedly old school and not remotely interactive. The New York Times has a series of maps tracking the various wildfire complexes. See also the Los Angeles Times interactive wildfires map, the address of which will probably work next year too. [Maps Mania/Nicholas Bogel-Burroughs]
Forecasting. NOAA’s High-Resolution Rapid Refresh (HRRR) atmospheric model includes an experimental smoke forecast. It and other smoke and fire models are available as hourly static images (see above) or via this interactive map. [Maps Mania/UWCIMSS]
Google is adding wildfire boundaries to Search and Maps: it will provide warnings to nearby users and have an impact on driving directions. [Engadget/TechCrunch/The Verge]
Australia’s Bushfires and Misleading Maps
Whenever there’s a major news event, there will be an outbreak of fake, misattributed or misleading images that purport to be about that event. That goes for maps as well.
Take the serious situation with Australia’s bushfires at the moment. Social media is jammed with maps showing practically the whole damn continent on fire, or superimposed on another continent to let people there know just how big Australia is (and also on fire). It’s a profoundly serious situation, and as NASA’s Joshua Stevens points out, it’s possible to present an accurate map that shows its seriousness without resorting to hyperbole.
The trouble is, social media thrives on hyperbole, because it thrives on “engagement”—which means outrage and anger and, as Joshua Emmons notes, as we get inured to a certain level of outrage, even more outrage is needed just to get noticed.
Which brings me to this thing, which is showing up all over the social web:

New York Times Maps of the California Wildfires
The New York Times maps ongoing wildfires in California—and the state of things is that I have to specify which: in 2019; the Easy, Getty and Kincade fires in Ventura, Los Angeles and Sonoma counties, respectively. The page also maps where PG&E engaged in preventative power outages to inhibit the spread of fires.
Mapping the Amazon Fires
Let’s start with the current situation map from Brazil’s own space agency, the Instituto Nacional de Pesquisas Espacias (INPE), which I’m surprised is still online. In July Brazil’s president, Jair Bolsonaro, accused the widely respected agency of lying about the scale of deforestation in the Amazon; INPE’s chief, Ricardo Galvão, was forced out earlier this month after defending the agency. After that, INPE said that fires were up 84 percent over the same period last year. (The ESA, for its part, tracked nearly four times as many fires in August as they did last year.)
Other raw data sources include the Copernicus Atmosphere Monitoring Service (CAMS), fire activity data from which can be viewed here; and MODIS data from NASA’s Terra and Aqua satellites. For a live feed of MODIS data on the Amazon fires, see the MODIS Wildfire Dashboard.
Meanwhile, NASA’s Earth Observatory posted MODIS imagery of several Amazon fires, and had this curious statement that seemed to minimize the scale of the problem: “As of August 16, 2019, an analysis of NASA satellite data indicated that total fire activity across the Amazon basin this year has been close to the average in comparison to the past 15 years. […] Though activity appears to be above average in the states of Amazonas and Rondônia, it has so far appeared below average in Mato Grosso and Pará, according to estimates from the Global Fire Emissions Database, a research project that compiles and analyzes NASA data.”
A subsequent NASA Earth Observatory post seems to contradict the one I mentioned earlier, pointing to “a noticeable increase in large, intense, and persistent fires burning along major roads in the central Brazilian Amazon” which “are more consistent with land clearing than with regional drought” and noted fire detections “higher across the Brazilian Amazon” since 2010.
Contextualizing the amount of fires seems to be a recurring theme in the reporting: the number of fires are up sharply over last year, but close to the average when taking a longer view. It’s helped a lot of bad and insincere actors make it harder to get to the heart of what’s going on over there. They can’t, after all, deny the satellite imagery or the remote sensing: we can see the fires. We can detect the emissions of smoke, carbon dioxide and carbon monoxide (1, 2, 3). We can map them. And those maps can help us understand what’s going on.
On the NGO front, InfoAmazonia has produced the above map comparing fires over the last 24 hours with historical fire data. (They have other maps on this subject as well.)
Note, too, the reference above to burning along major roads. Tim Wallace crunches MODIS date from 2012 onward and teases out some patterns in the fires.
And the New York Times, where Tim used to work, has a map correlating the position of the current Amazon fires along the edges of past deforestation. The Times also has maps showing maps on a month-by-month basis and comparing August 2019 with the August average over the past decade.
