AI-generated Key Takeaways
-
This dataset, LANDSAT/LT4_L1T_ANNUAL_EVI, has been deprecated and users should switch to LANDSAT/LT04/C01/T1_ANNUAL_EVI.
-
It provides Landsat 4 TM annual composites, using top-of-atmosphere (TOA) reflectance, from 1982 to 1993.
-
The Enhanced Vegetation Index (EVI) is calculated from the Near-IR, Red, and Blue bands and ranges from -1.0 to 1.0.
-
This dataset is provided by USGS and resides in the public domain.
-
The USGS should be acknowledged as the data source when using this dataset.

Description
These Landsat 4 TM 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 Enhanced Vegetation Index (EVI) is generated from the Near-IR, Red and Blue bands of each scene, and ranges in value from -1.0 to 1.0. See Huete et al. (2002) for details.
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.
