It measures the spectral distance from a reference point using Red and Near-IR bands. The data is a composite of all annual scenes, with the most recent pixel value retained. USGS stopped producing pre-collection Landsat as of May 2017. The dataset is now superseded and is to be replaced. The data is public domain.\n"]]
