NDVI

The Normalized Difference Vegetation Index (NDVI) data product is derived from satellite data and is available for the period from March 2000 to December 2006.

This file includes Moderate Resolution Imaging Spectroradiometer (MODIS) 250-meter 10-day composite imagery for B1,B2, B3, B4, B5, B6, and B7 top-of-atmosphere reflectance, and geometric data. The NDVI data product is generated from MODIS orbital granules of Level 1B (MOD02) Collection 5. First, the bands 3-7 data are downscaled from original 500-meter to 250-meter resolution using an algorithm developed at CCRS. All 7 bands are reprojected to an LCC map which covers the whole Canada. Then the clearer sky pixels are selected to generate a 10-day composite imagery from which is derived the NDVI data product.
