Landsat 7 Collection 1 Tier 1 Annual NDVI Composite [deprecated]

AI-generated Key Takeaways

• This dataset, LANDSAT/LE07/C01/T1_ANNUAL_NDVI, has been superseded by a newer version and is considered deprecated.

• It provides Landsat 7 Collection 1 Tier 1 annual composites, calculated using top-of-atmosphere (TOA) reflectance and Normalized Difference Vegetation Index (NDVI).

• The dataset covers the period from 1999 to 2021, with composites created from all scenes within each year.

• Landsat data is public domain and can be freely used, but requires acknowledgement of the USGS as the data source.

• Earth Engine, the platform hosting this dataset, is free for research, education, and nonprofit purposes.

Caution: This dataset has been superseded by LANDSAT/COMPOSITES/C02/T1_L2_ANNUAL_NDVI.

Description

These Landsat 7 Collection 1 Tier 1 composites are made from Tier 1 orthorectified scenes, using the computed top-of-atmosphere (TOA) reflectance. See Chander et al. (2009) for details on the TOA computation.

The Normalized Difference Vegetation Index is generated from the Near-IR and Red bands of each scene as (NIR - Red) / (NIR + Red), and ranges in value from -1.0 to 1.0.

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.
