EVI: Malaria Atlas Project Gap-Filled Enhanced Vegetation Index (Monthly 1km)

  • This dataset, part of the Malaria Atlas Project Catalog, provides monthly 1km Enhanced Vegetation Index (EVI) data derived from gap-filled and BRDF-corrected MODIS imagery.

  • The data covers the period from February 2001 to December 2024 and has a spatial resolution of 5000 meters per pixel.

  • The single band available, Mean, represents the mean EVI value with estimated minimum and maximum values clipped to 0 and 1 respectively.

  • The dataset is available under the CC-BY-NC-SA-4.0 terms of use and should be cited using the provided publication by Weiss et al. (2014).

  • Users can explore this dataset within the Google Earth Engine platform, with sample code provided for visualization in the Code Editor.

Description

The underlying dataset for this Enhanced Vegetation Index (EVI) product is MODIS BRDF-corrected imagery (MCD43B4), which was gap-filled using the approach outlined in Weiss et al. (2014) to eliminate missing data caused by factors such as cloud cover. After gap-filling the data was clipped to thresholds of [0, 1] to ensure valid values.

The gap-filled 8-daily ~1km outputs are then aggregated temporally to produce monthly and annual products.
