Landsat’s Role in Managing Wildland Fires
Worldwide, fire plays a critical role in maintaining healthy forests, but fire can also be damaging. Homes are destroyed and the effects on air quality can be felt for miles. Forest fires are occurring more often and with greater intensity than in years past, and Landsat plays a critical role in understanding the impact. Landsat data enables land managers and scientists to assess the severity and extent of large fires as they plan recovery efforts; to improve safety and prevent damage to life, property and natural resources; to estimate how much pollution burning releases into the air; and to monitor the post-fire recovery of burned areas. Landsat satellites have been collecting information about forest fires since the 1970s. Landsat plays an important role in assessing the impact of fires on forest ecosystems and human society. Landsat satellites document the location and extent of burned areas, how severely fires burn, and the subsequent regrowth of the land after a forest fire. All this information helps land managers better manage our forests and other natural resources in the context of fire.
Over the past few years, machine learning techniques have been increasingly used to analyze the vast amount of data collected by the Landsat mission, which has been circling the globe for over 50 years.
Merging data from multiple satellites, OPERA can help government agencies, disaster responders, and the public access data about natural and human impacts to the land.
Thirty-meter Landsat 8 and 9 data have been added to NASA’s Fire Information for Resource Management System (FIRMS).
Landsat has shown that wildfires and climbing temperatures have caused a 6.7 percent decline in California tree cover since 1985.
