Hybrid Land Cover Product: A hybrid circumpolar 1 km land cover product
Abstract
This 1km hybrid land cover map of the Arctic-Boreal region was created by integrating global and regional datasets using a machine learning-based fusion approach. It includes 35 classes such as forest types, shrublands, and wetlands, and captures the fine-scale spatial heterogeneity essential for understanding permafrost dynamics. The product improves upon existing global maps by offering greater thematic detail and consistency across the circumpolar Arctic, supporting ecological research and climate modeling. **This dataset supports the manuscript "Fusing Regional and Global Land Cover Maps: An Application for Ecosystem Modeling Across High Latitudes" which is currently under review.A DOI for the paper will be added here upon publication.

However, global land cover products often fail to capture the spatial heterogeneity and ecological detail required for Arctic-Boreal applications. This circumpolar 1-km land cover map integrates global (ESA-CCI-LC) and regional datasets using a machine learning-based fusion approach to generate 35 detailed land cover classes, including forest, shrubland, and wetland types. The map ensures thematic richness and consistency across the Arctic-Boreal zone, supporting improved climate modeling and ecological analysis. Further methodological details can be found in the associated publication. Figure 1. The overview of the hybrid land cover product Class Class Name 6 Poplar Forest 7 Oak Forest 10 Other Pine Forest
