The Normalized Difference Vegetation Index (NDVI) is a numerical indicator that uses the red and near-infrared spectral bands. NDVI is highly associated with vegetation content. High NDVI values correspond to areas that reflect more in the near-infrared spectrum. Higher reflectance in the near-infrared correspond to denser and healthier vegetation.
NDVI can be used in numerous remote sensing applications, like crop phenology determination, crop type identification, crop health, forest monitoring etc.
Our Spaceye product uses the near-infrared and red spectral bands from various satellites (Landsat 8 OLI, Landsat 5 TM, Sentinel 2 MSI) to calculate the NDVI with the following formulas (one for each satellite):
Our NDVI product is produced for the whole globe from 1985 to today with timely temporal resolution!
