Enhanced Vegetation Index (2012-03-05)

Full description

Global MODIS vegetation indices are designed to provide consistent spatial and temporal comparisons of vegetation conditions. Enhanced Vegetation Index (EVI) minimizes canopy background variations and maintains sensitivity over dense vegetation conditions. The EVI also uses the blue band to remove residual atmosphere contamination caused by smoke and sub-pixel thin cloud clouds. The MODIS NDVI and EVI products are computed from atmospherically corrected bi-directional surface reflectances that have been masked for water, clouds, heavy aerosols, and cloud shadows.

Data are derived from the MODIS Land Products that are distributed by the LPDAAC as tiles from a global sinusoidal projection. Tiles for selected products for Australia have been downloaded and then mosaiced and remapped using the Modis Reprojection Tool (MRT). The products have been split into individual bands to reduce file size and have been reformatted to ensure consistency in SDS and attribute nomenclature.
