AI-generated Key Takeaways
-
This Landsat 7 Collection 1 Tier 1 annual composite dataset has been superseded by a newer version, LANDSAT/COMPOSITES/C02/T1_L2_ANNUAL_BAI.
-
It provides Burn Area Index (BAI) data derived from Landsat 7 imagery, calculated using top-of-atmosphere reflectance.
-
The dataset covers the period from 1999 to 2021, with annual composites created using the most recent pixel as the composite value.
-
BAI measures the spectral distance of a pixel from a charcoal reference, emphasizing burn scars in post-fire images.
-
Landsat datasets are public domain and can be used freely with proper USGS acknowledgement.

Description
These Landsat 7 Collection 1 Tier 1 composites are made from Tier 1 orthorectified scenes, using the computed top-of-atmosphere (TOA) reflectance. See Chander et al. (2009) for details on the TOA computation.
The Burn Area Index (BAI) is generated from the Red and Near-IR bands, and measures the spectral distance of each pixel from a reference spectral point (the measured reflectance of charcoal). This index is intended to emphasize the charcoal signal in post-fire images. See Chuvieco et al. (2002) for details.
These composites are created from all the scenes in each annual period beginning from the first day of the year and continuing to the last day of the year. All the images from each year are included in the composite, with the most recent pixel as the composite value.
