Landsat 4 TM Annual EVI Composite [deprecated]

  • This dataset, consisting of Landsat 4 TM annual composites of Enhanced Vegetation Index (EVI), is now deprecated and has been superseded by LANDSAT/LT04/C01/T1_ANNUAL_EVI.

  • The dataset covers the period from 1982 to 1993 and was produced by the USGS.

  • The EVI band has a pixel size of 30 meters and values range from -1.0 to 1.0.

  • Landsat datasets are in the public domain and can be used without copyright restriction, with acknowledgement of the USGS as the data source.

  • This dataset is complete as of May 1, 2017, when the USGS stopped producing Pre-Collection Landsat.

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.
