SPOT-VGT Data Products
SPOT-VGT (Vegetation) satellite data, operational from 1998 to 2014, offered valuable insights into global vegetation dynamics. It captured imagery primarily in red and near-infrared bands, enabling the calculation of key vegetation indices like NDVI.
Physical products of SPOT VEGETATION (VGT-P)
VGT-P (P= physical) products are adapted for scientific applications requiring highly accurate physical measurements. The data is corrected for system errors (error registration of the different channels, calibration of all the detectors along the line-array detectors for each spectral band) and resampled to predefined geographic projections chosen by the user. The pixel brightness count is the ground area’s apparent reflectance as seen at the top of atmosphere (TOA). Auxiliary data supplied with the products allow users to process the original reflectance values using their own algorithms. The image products cover all or a part of a VEGETATION segment (data strip over land). The VEGETATION instrument is operational since April 1998, first with VGT1, from March 2003 onwards, with VGT2.

Global 1 Day Synthesis of SPOT VEGETATION Images (VGT-S1)
VGT-S1 products (daily synthesis) are composed of the ‘Best available’ ground reflectance measurements of all segments received during one day for the entire surface of the Earth. This is done for each of the images covering the same geographical area. The areas distant from the equator have more overlapping parts so the choice for the best pixel will be out of more data. These products provide data from all spectral bands, the NDVI and auxiliary data on image acquisition parameters. The VEGETATION instrument is operational since April 1998, first with VGT1, from March 2003 onwards, with VGT2.

Global 10 Days Synthesis of SPOT VEGETATION Images (VGT-S10)
The VGT-S10 are near-global, 10-daily composite images which are synthesised from the ‘best available’ observations registered in the course of every ‘dekad’ by the orbiting earth observation system SPOT-VEGETATION. The products provide data from all spectral bands (SWIR, NIR, RED, BLUE), the NDVI and auxiliary data on image acquisition parameters. The VEGETATION system allows operational and near real-time applications, at global, continental and regional scales, in very broad environmentally and socio-economically critical fields. The VEGETATION instrument is operational since April 1998, first with VGT1, from March 2003 onwards, with VGT2.
