Secondary forest samples for VCT

The European Space Agency Climate Change Initiative-Land Cover (ESA_CCI-LC) project provides a consistent annual global land cover map with a 300-m spatial resolution for 1992 to 2020. The stable and secondary forest maps were individually derived based on ESA_CCI-LC by yearly overlaying. Pixels of secondary forest were identified as transitions in land cover to forest over the study period. The samples of stable and secondary forests were filtered based on various conditions, including an area > 4,500 m2, random selection, and data conversion. In the dataset, the code of age_cci presents the age of secondary forest calculated from ESA_CCI-LC in 2020, the code of year presents the year of establishment of secondary forest stand.
