GLC_FCS30D: global 30-m land-cover dynamic monitoring product with a fine classification system from 1985 to 2022

GLC_FCS30D is the first global fine land cover dynamic product at a 30-meter resolution that adopts continuous change detection. It utilizes a refined classification system containing 35 land categories and covers the time span from 1985 to 2022. Before the year 2000, the update cycle was every 5 years, while after 2000, it is updated annually.
