USGS Landsat 7 Collection 1 Tier 1 and Real-Time data TOA Reflectance (LANDSAT/LE07/C01/T1_RT_TOA)
Landsat 7 Collection 1 Tier 1 and Real-Time data
calibrated top-of-atmosphere (TOA) reflectance.
Calibration coefficients are extracted from the image metadata. See
Chander et al. (2009) for details on the TOA computation.
| Name | Description | Gee:wavelength |
|---|---|---|
| B1 | Blue | 0.45 - 0.52 µm |
| B2 | Green | 0.52 - 0.60 µm |
| B3 | Red | 0.63 - 0.69 µm |
| B4 | Near infrared | 0.77 - 0.90 µm |
| B5 | Shortwave infrared 1 | 1.55 - 1.75 µm |
| B6_VCID_1 | 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. | 10.40 - 12.50 µm |
| B6_VCID_2 | 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. | 10.40 - 12.50 µm |
| B7 | Shortwave infrared 2 | 2.08 - 2.35 µm |
| B8 | Panchromatic | 0.52 - 0.90 µm |
| BQA | Landsat Collection 1 QA Bitmask ([See Landsat QA page](https://landsat.usgs.gov/collectionqualityband)) |
