AI-generated Key Takeaways
-
This dataset contains annual Normalized Difference Vegetation Index (NDVI) composites from Landsat 7 Level L1T scenes.
-
The dataset covers the period from 1999-01-01 to 2017-01-01 and is no longer being updated as Pre-Collection Landsat production ceased on May 1, 2017.
-
This dataset has been superseded and users should switch to a Collection 1-based dataset like LANDSAT/LE07/C01/T1_ANNUAL_NDVI.
-
The NDVI band has a pixel size of 30 meters and ranges from -1 to 1.
-
Landsat datasets are in the public domain and can be used, transferred, or reproduced without copyright restriction, with suggested acknowledgement to the U.S. Geological Survey (USGS).

Description
These Landsat 7 composites are made from Level L1T orthorectified scenes, using the computed top-of-atmosphere (TOA) reflectance. See Chander et al. (2009) for details on the TOA computation.
As of May 1, 2017, the USGS is no longer producing Pre-Collection Landsat, and therefore this collection is complete. Please switch to a Collection 1-based dataset. See this documentation page for more information.
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.
