USGS sets earth observation precedent with Landsat Collection 2Dataset.
Landsat Collection 2 marks the second major reprocessing campaign on the USGS Landsat archive since 2016, resulting in several data product improvements that harness recent advancements in data processing, algorithm development, and data access and distribution capabilities. The USGS switched to a collections-based Landsat archive management strategy four years ago in recognition of the need for consistent Landsat 1-8 sensor data and in anticipation of future periodic reprocessing of the archive to reflect new sensor calibration knowledge.
