![]() ![]() Because of its finer spatial resolution (375 meters), it can detect smaller fires on the ground with a bit more accuracy.ĭetecting forest fires is just one of the hundreds of remote sensing and satellite applications in use today. ![]() VIIRS: Likewise, VIIRS on board the NASA/NOAA Suomi NPP detects active forest fires based on thermal anomalies.As explained above, it detects active fires by comparing temperature to neighboring pixels but it depends on the severity and extent of the fire. MODIS: On board Terra and Aqua satellites, MODIS has a pixel resolution of 1 km.But if the fire is too small to detect due to the spatial resolution of the sensor, the satellite won’t be able to detect it. If the difference is over a given threshold, it confirms the “hot spot” as an active wildfire. The fire detection algorithm compares the temperature of a potential fire with the temperature of the land around it. Fortunately, satellites can track forest fires and deliver warnings to emergency crews. is visible in this image, acquired on August 6, 2021, with the Geostationary Operational Environmental Satellite 17 (GOES-17) (above). History shows that when wildfires get out of hand, they can be costly and deadly to people nearby. The enormous blanket of smoke from the Dixie fire and dozens of others burning across the western U.S. Monitoring Real-Time Forest Fires with MODIS and VIIRS As you can see below, here is a satellite view of the December 2017 wildfires in California. If you downloaded the correct date and time, you should be able to see the forest fire. Finally, drag and drop the Landsat image into Google Earth Pro without any extra processing. The image type you want is Landsat Look with Geographic Reference (about 10MB). If you want to see a snapshot of the fire, your best chance is to use a Landsat scene from the USGS Earth Explorer.įortunately, we have a tutorial on how to download Landsat data. As you can see above, the latest forest fires will pop up with fire symbols. Next, drag and drop the KMZ into Google Earth Pro. But really, all it takes is a bit of legwork to get started.įirst, download the latest active fire data from NASA. ![]() Even though the imagery is usually less than a year old, chances are that you won’t see a forest fire in the application. The legacy geospatial data, products and services as well as new AFM capabilities are now available. ![]() And the best part is that it’s never a cloudy day. The Active Fire Mapping (AFM) website is now retired. Google Earth Pro is a handy tool that helps you sight-see the planet. ![]()
