Landsat Advisory Group October 2020 Report Cover

During the October 2020 National Geospatial Advisory Committee (NGAC) meeting, the Landsat Advisory Group (LAG) presented the report “Landsat Data: Community Standards for Data Calibration”.

The paper describes how Landsat data have become widely recognized as a radiometric and geometric calibration “gold” standard or  reference for other multi-spectral satellite data. Since Landsat is the longest running, multi-decadal record of calibrated observations of the earth’s surface, it’s possible not only to evaluate change over time but also to register other data sources to Landsat data that were collected in the same timeframe.
