This repository includes the algorithm (Random Forest) that was developed to estimate pasture properties of Portuguese Sown biodiverse pastures rich in legumes (SBP) derived from Sentinel-2 data. The considered properties are:

  • Standing biomass (kg/ha)
  • Legumes fraction (-)
  • Nitrogen content (g/kg)
  • Phosphorus content (g/kg)

Used scripts are in folder "train_models" and the best trained models are in folder "models"

Two cross-valiadtion approaches were used, whcih lead to set of models:

  • Random cross-validation (RN-CV): random approach with random selection of the folds
  • Leave-location-and-year-out cross-validation (LLYO-CV): each fold is the set of all observations from each farm and year

Usage

  • Requires scikit-learn library
  • Requires joblib library
  • Download folder "models" folder
  • Prepare input data (see raw data file used in "Raw data folder"
  • Use the individual models in the "models" folder using the input data file

Example of application of the models
