New Book "Global Land Cover Validation: Methodology, Tools, and Practices" in ISPRS Book Series
Accurate characterization of land cover at global, regional, and local scales is essential for sustainable development monitoring, environmental change studies, natural resource management, disaster assessment and mitigation, and many other applications. The thematic accuracy of these land cover data products can be documented through sample-based validation or comparison with existing reference data. The accuracy assessment results will not only help the users to understand the uncertainty and the scope of data applications but also enable the producers to examine and analyze the types, sources, and spatial distribution of errors.
This book aims to summarize and report the major research achievements and validation results under the global land cover (GLC) 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. Chapters 2–5 provide systematic introductions to the major methodology of finer-resolution GLC map validation, including sampling design, reference data collection, sample labeling, and accuracy assessment. Chapter 6 introduces the online validation tools that have been developed, including their design, considerations, and functionalities. Chapter 7 presents the international validation practices and the results of validating GlobeLand30 at country, regional, and global scales. Future directions are also discussed at the end.
Edited by Jun Chen (National Geomatics Center of China), Xiaohua Tong (Tongji University), Huan Xie (Tongji University), Lijun Chen (National Geomatics Center of China) and Songnian Li (Toronto Metropolitan University), this book offers the following features:
- Presents complete coverage of land cover validation, from concepts, methodology, and collaborative tools to applications.
- Details algorithms, techniques, and methods for land cover validation, including sampling, judgment, and accuracy assessment.
- Reviews some of the software tools that can be used for GLC validation and discusses the issues related to the design, usability, efficiency, and limitations of these tools.
- Highlights case studies of validation at global, regional, and national scales, which can serve as great references for researchers.
- Provides an extensive bibliography covering the whole scope of land cover validation.
Global Land Cover Validation: Methodology, Tools, and Practices serves as a reference for those engaged in land cover validation, especially at a global scale, including students, professionals, researchers, and general practitioners. It is also an excellent resource for professionals involved in
sustainable development monitoring, environmental change studies, natural resource management, disaster assessment and mitigation, and many other applications.
