Description
These 3-year composites were created from all Landsat 7 images in the specified composite period, excluding images marked with a negative sun elevation in their metadata. The composites were created using the ee.Algorithms.Landsat.simpleComposite() method with its default settings. Reflectance ([0,1]) in bands B1, B2, B3, B4, B5, and B7 is scaled to 8 bits ([0,255]) and temperature in band B6_VCID_2 is converted to units of Kelvin-100.
Bands
Bands
| Name | Pixel Size | Wavelength | Description |
|---|---|---|---|
B1 |
30 meters | 0.45 - 0.52 μm | Blue |
B2 |
30 meters | 0.52 - 0.60 μm | Green |
B3 |
30 meters | 0.63 - 0.69 μm | Red |
B4 |
30 meters | 0.77 - 0.90 μm | Near infrared |
B5 |
30 meters | 1.55 - 1.75 μm | Shortwave infrared 1 |
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. |
B7 |
30 meters | 2.08 - 2.35 μm | Shortwave infrared 2 |
