Vineyard's Biophysical Status Service – High Resolution

The Vineyard’s Biophysical Status Service provides information on the biophysical status of vineyard fields for a user-selected period. Two products are delivered through this EO service: vigor and biomass. The Soil Adjusted Vegetation Index (SAVI) is used to provide information on vineyard vigor, while two different approaches have been used to provide information on biomass. On one side, the enhanced Normalized Difference Vegetation Index (eNDVI) provides biomass information in a categorical manner. On the other side, a more complex approach, the CASA model, using not only optical data but also climate variables, is used to provide biomass rates.

This service can be requested by LEONSEGS' users at High Resolution (HR) or Very High Resolution (VHR). The system selects the best input data from the available options based on the user’s preferences. For the HR option, both vigor and biomass products can be generated using either Sentinel-2 or Landsat 8/9 data, with the system automatically selecting the best available option. Biomass rates based on the CASA model are only delivered when Sentinel-2 data are used, as this product is not available for Landsat 8/9.

This service is part of the set of Earth Observation (EO) services developed in order to illustrate, test, validate and demonstrate the LEONSEGS capabilities. The defined use cases are implemented and tested in two Areas of Interest (AoIs), located in Spain and Austria. This service is only provided for the Spanish use case, focused on vineyard monitoring. 

This record provides examples of the outputs produced by the LEONSEGS system in response to a user requesting the Vineyard’s Biophysical Status service at HR level.

Outputs:
• The Soil Adjusted Vegetation Index (SAVI), used to provide information on vineyard vigor. 
• The biomass, used to provide quantitative information on biomass (g/m2/day)
• The eNDVI, used to provide qualitative information on biomass 

For each output, the following files are provided:
      - GeoTIFF raster containing the original values
      - Categorized GeoTIFF raster
      - RGB visualization GeoTIFF
      - PNG legend associated with the RGB visualization
      - Raster footprint geometry (.wkt)
      - ISO 19115/19139 metadata (.xml)
      - STAC metadata (.geojson)

The categorized values have been specifically adjusted for vineyard crops according to crop phenology; therefore, these values are not applicable to other crop types.

For a given EO product, multiple examples may be available, representing the full range of satellite missions: Landsat 8, Landsat 9, Sentinel-2A, Sentinel-2B, and Sentinel-2C.
