This book aims to summarize and report the major research achievements and validation results of the Global Land Cover initiative led by the Group of Earth Observation (GEO). The first part of the book introduces the major tasks and challenges facing the validation of finer-resolution GLC maps and presents the concepts and overall framework of the GEO-led initiative. Part 2 provides a systematic introduction to the major methodology of finer-resolution GLC map validation, including sampling design, reference data collection, sample labeling, and accuracy assessment. Part 3 introduces the online validation tools that have been developed, including their design, considerations, and functionalities. Part 4 presents the international validation practices and the results of validating GlobeLand30 at country, regional, and global scales. Future directions are also discussed.
