This book features a comprehensive series of the overview articles on all relevant aspects of forest structure estimation from space and related fields. The overview articles in this book discuss the importance of the derived products for earth system science and policy, the latest earth observation system and techniques, aspects of ground data collection for contextualisation and validation and the consistent generation of estimates from multiple data stream.
