Classificazione della tessitura USDA a profondità del suolo di 0-20 cm e 20-50 cm.
Nelle aree di giungla fitta (generalmente nell'Africa centrale), l'accuratezza del modello è
bassa e pertanto potrebbero essere visibili artefatti come bande (strisce).
Le previsioni sulle proprietà del suolo sono state effettuate da
Innovative Solutions for Decision Agriculture Ltd. (iSDA)
con dimensioni dei pixel di 30 m utilizzando il machine learning combinato con dati di telerilevamento
e un set di addestramento di oltre 100.000 campioni di suolo analizzati.
