Accurate and complete data on fire locations and burned areas are important for a variety of applications. Imagery collected by the family of Landsat sensors is useful and appropriate for monitoring the extent of area burned, and provide spatial and temporal resolutions ideal for science and management applications. In recent years, the Monitoring Trends in Burn Severity Project (MTBS) provided consistent, 30 meter resolution burn severity and perimeters of fires across the United States from 1984-2015 based on Landsat imagery; Australia released its Fire Scars (AFS) products derived from all available Landsat 5, 7 and 8 images. Both 30 meter burned area products can be freely accessed from the website. However, to date, there currently lacks an independent validation to the MTBS and AFS products. In this paper, a study was performed to validate these two 30 meter burned area products. Validation data covered a range of ecosystems and fire regimes, and the acquisition time of the validation data were in different seasons and spanned from 1980s to 2010s. It was found that the accuracy of the MTBS burned area products ranged from 76.67% to 100%, and the average accuracy was 97.24 %. While the AFS product accuracy ranged from 25.71% to 100%, with average accuracy of 81.75 %.
