Landsat 4 TM Collection 1 Tier 1 Annual NDVI Composite [deprecated]

AI-generated Key Takeaways

• This Landsat 4 TM dataset provides annual Normalized Difference Vegetation Index (NDVI) composites from 1982 to 1993.

• It has been superseded by a newer dataset, LANDSAT/COMPOSITES/C02/T1_L2_ANNUAL_NDVI, and is considered deprecated.

• The NDVI is calculated using top-of-atmosphere reflectance and ranges from -1.0 to 1.0.

• Landsat datasets are in the public domain and can be used freely with proper USGS acknowledgement.

• Composites include all scenes from each year, with the most recent pixel representing the composite value.

Caution: This dataset has been superseded by LANDSAT/COMPOSITES/C02/T1_L2_ANNUAL_NDVI.

Description

These Landsat 4 TM 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.
