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.

B5
30 meters
1.55 - 1.75 μm
Shortwave infrared 1
B6_VCID_1
60 meters
10.40 - 12.50 μm
Low-gain Thermal Infrared 1. This band has expanded dynamic range
and lower radiometric resolution (sensitivity), with less
saturation at high Digital Number (DN) values. Resampled from
60m to 30m.
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.
