Biophysical Processor Description

Processor Description

The Biophysical Processor LANDSAT8 is optimized to use a LANDSAT8 product as input instead of a Sentinel2 product, however it is only capable of computing LAI, FAPAR and FVC indexes.

I/O Parameters Tab

Source Product Group

Name: Used to select the spectral source product. The source product shall be a LANDSAT8 product. Use the ... button to open a data product currently not opened in the application. The algorithm is calibrated for top-of-canopy reflectances and depends on the acquisition geometry, so it requires slope-effect corrected reflectances to give optimal results

Target Product Group

Name: Used to specify the name of the target product.

Save to: Used to specify whether the target product should be saved to the file system. The combo box presents a list of file formats.

Open in SNAP: Used to specify whether the target product should be opened in the application. When the target product is not saved, it is opened automatically.

Processing Parameters Tab

    Compute LAI:
    Enable/Disable the computation of LAI (Leaf Area Index) in the output product

    Compute FAPAR:
    Enable/Disable the computation of FAPAR (Fraction of Absorbed Photosynthetically Active Radiation) in the output product

    Compute FVC:
    Enable/Disable the computation of FVC (Fraction of Vegetation Cover) in the output product
