Preface

During the past few decades, the complexity of global change and its interaction with human activities have posed significant challenges to the scientific community. Driven by the needs of societal and economic development, geospatial technology has become one of the three emerging technologies in the 21st century. As the frontiers of geospatial technology, Earth observation and remote sensing techniques have received an increasing interest in the academic, governments, industries, and the general public, and have been widely applied to monitor, assess and predict global and regional ecosystems, environments, and resources, which provide potential solutions to many key issues in the global change research.
