Abstract Water hyacinth is an aquatic free-floating plant that highly invasive, to the extent it now present in most freshwater bodies sub-tropical and tropical regions worldwide. Due ecological socio-economic damages these plants can cause, monitoring their spatial coverage seasonality key for development of timely efficient mitigation measures. Hyacinth patches are sufficiently large be detec...
