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 32-day period beginning from the first day of the year and continuing to the 352nd day of the year. The last composite of the year, beginning on day 353, will overlap the first composite of the following year by 20 days. All the images from each 32-day period are included in the composite, with the most recent pixel as the composite value.

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. |
