Forest Visitor Maps for each national forest and grassland provide forest-wide information on attractions, facilities, services, and opportunities.Many Forest Visitor Maps are also available for purchase as georeferenced PDFs on Avenza, for use on mobile devices. Geological Survey Store, many Forest Service offices and other retail outlets. These maps are available for purchase at the U.S. “ A Guide To Your National Forests” is a free brochure showing locations of national forests and grasslands along with contact information.įorest Visitor Maps, National Forest Atlas, and Wilderness Maps We've released the next generation Interactive Visitor Map! Visitor Map 2.0, provides the public with an online view of Forest Service roads, trails, recreation sites, wilderness areas, and wild & scenic rivers. 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.The Forest Service publishes a variety of map products to help you plan your next adventure or enjoy your next visit! National Overview Maps 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. History shows that when wildfires get out of hand, they can be costly and deadly to people nearby. 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 some 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. And the best part is that it’s never a cloudy day. Google Earth Pro is a handy tool that helps you sight-see the planet.
