AI-generated Key Takeaways
-
This dataset provides Landsat 7 5-year TOA percentile composites, created from images between 1999 and 2008.
-
The composites were generated using all Landsat 7 images from the specified period, excluding those with negative sun elevation metadata, and processed using the
ee.Algorithms.Landsat.simpleComposite()method. -
It includes spectral bands such as Blue, Green, Red, Near Infrared, Shortwave Infrared 1 & 2, and Thermal Infrared, with varying pixel sizes and wavelengths.
-
Landsat datasets are in the public domain and can be used freely, but require acknowledgement of the USGS as the data source.
-
The dataset is accessible through Google Earth Engine, a platform for large-scale geospatial analysis.

Description
These 5-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 |
