The Level-2 VGP SYN product (SY_2_VGP) is produced by the Global Synergy Level-1/2 software and contains 1 km VEGETATION-like product TOA reflectances.
The "1 km VEGETATION-like product" label means that measurements are provided on a regular latitude-longitude grid, with an equatorial sampling distance of approximately 1 km. This product is restricted in longitude, including only filled ones.
This product is referred to as SPOT Continuity Product, adapted for scientific applications requiring highly accurate physical measurements. As a consequence, data are corrected for systematic errors (such as error registration of the different channels or calibration of all the detectors along the line-array detectors for each spectral band) and resamples to predefined geographic projections.
The measurements files focus on four specific spectral bands.
Several additional pieces of information are contained in this product but provided on a sub-sampled grid (every 16th pixel).
