Page Summary
-
The dataset consists of Landsat 7 Collection 1 Tier 1 annual raw composites made from orthorectified scenes.
-
These composites use DN values representing scaled, calibrated at-sensor radiance.
-
Composites are created from all scenes within each annual period, with the most recent pixel used as the composite value.
-
The dataset is available from 1999-01-01T00:00:00Z to 2021-01-01T00:00:00Z.
-
This Landsat dataset is in the public domain and requires acknowledgement of the USGS as the data source when used.

Description
These Landsat 7 Collection 1 Tier 1 composites are made from Tier 1 orthorectified scenes, using the DN values, representing scaled, calibrated at-sensor radiance.
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.

B6_VCID_2 |
60 meters | 10.40 - 12.50 μm | High-gain Thermal Infrared 1. This band has higher radiometric resolution (sensitivity), although it has a more restricted dynamic range. Resampled from 60m to 30m. |
