#### Description

Landsat 7 Collection 2 Tier 1 DN values, representing scaled, calibrated at-sensor radiance.

Landsat scenes with the highest available data quality
are placed into Tier 1 and are considered suitable for time-series processing
analysis. Tier 1 includes Level-1 Precision Terrain (L1TP) processed data
that have well-characterized radiometry and are inter-calibrated across the
different Landsat sensors. The georegistration of Tier 1 scenes will be
consistent and within prescribed tolerances \[\<=12 m root mean square error
(RMSE)\]. All Tier 1 Landsat data can be considered consistent and
inter-calibrated (regardless of sensor) across the full collection. See more
information [in the USGS
docs](https://www.usgs.gov/core-science-systems/nli/landsat/landsat-collections).

Note that [Landsat 7's orbit has been drifting to an earlier acquisition time since
2017](https://www.sciencedirect.com/science/article/pii/S2666017221000134?via%3Dihub).
