AI-generated Key Takeaways
-
The dataset provides annual Landsat Collection 2 Tier 1 Level 2 composites, derived from orthorectified scenes, spanning from 1984 to 2024.
-
It features the Normalized Difference Vegetation Index (NDVI), calculated from Near-IR and Red bands, ranging from -1.0 to 1.0, representing vegetation health.
-
Composites include all scenes within each year, prioritizing the most recent pixel for the composite value, with limitations for Landsat 7 and 8 due to orbital drift and pointing issues.
-
The dataset is provided by USGS and is in the public domain, encouraging use with proper citation.
-
Earth Engine provides tools for analysis and visualization of this dataset, offering free access for research, education, and non-profit purposes.

Description
These Landsat Collection 2 Tier 1 Level 2 composites are made from Tier 1 Level 2 orthorectified scenes.
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.
Notes:
Only daytime images with WRS_ROW < 122 are included.
For Landsat 7 , images after 2017-01-01 are excluded due to orbital drift.
For Landsat 8, images before 2013-05-01 are excluded due to pointing issues.
