The FSSCAT products are freely accessible in accordance with ESA's Earth observation data policy.

The FSSCat collection provides hyperspectral data coverage over a number of locations around the world, as measured by the HyperScout 2 sensor.

The FSSCat hyperspectral data products are comprised of 50 spectral bands, covering a spectral range of 450–950 nm with a spectral resolution of 18 nm (at FWHM). Imagery is available with an along-track ground sampling distance (GSD) of 75 m. To ensure a high degree of radiometric accuracy, HyperScout 2 data are validated through comparison with Sentinel-2 data products.

The processing level of the data is L1C – calibrated top-of-atmosphere radiance, reflectance, or brightness temperature. The raster type of the L1C data product is a GRID – a 2D or 3D raster where the (geo)location of the data is uniquely defined by:

• the upper left pixel location of the raster,
• the pixel size, and
• the projection parameters (if georeferenced). 

The third dimension can, for example, represent a spectral or third spatial dimension. 

The L1C VNIR data product includes a hyperspectral cube of TOA reflectance in the VNIR range, as well as relevant metadata that adheres to EDAP's best practice guidelines. This product consists of georeferenced and ortho-rectified image tiles containing spectral reflectance data at the top of the atmosphere. 

Each image tile includes radiometrically corrected and ortho-rectified band images projected onto a map, together with geolocation information and the coordinate system used. Each image pixel provides TOA spectral reflectance data in scaled integers, conversion coefficients for spectral radiance units, viewing and solar zenith and azimuth angles, and quality flags.
