Landsat 8 Annual BAI Composite
These Landsat 8 composites are made from Level L1T orthorectified scenes, using the computed top-of-atmosphere (TOA) reflectance. See Chander et al. (2009) for details on the TOA computation.
As of May 1, 2017, the USGS is no longer producing Pre-Collection Landsat, and therefore this collection is complete. Please switch to a Collection 1-based dataset. See this documentation page for more information.
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
这些Landsat 8的合成物是由L1T级正射场景制作的，使用计算的大气层顶部（TOA）反射率。关于TOA计算的细节，见Chander等人（2009）。
从2017年5月1日起，美国地质调查局不再生产预收集的Landsat，因此这个收集已经完成。请切换到基于集合1的数据集。更多信息请参见本文档页面。
烧伤面积指数（BAI）由红色和近红外波段产生，测量每个像素与参考光谱点（测得的木炭反射率）的光谱距离。这个指数的目的是强调火后图像中的木炭信号。详见Chuvieco等人（2002）。
这些合成物是由每个年度的所有场景创建的，从该年的第一天开始，一直到该年的最后一天。每一年的所有图像都包括在合成中，最近的像素为合成值
