LiDAR Principles, Processing and Applications in Forest Ecology introduces the principles of LiDAR technology and explains how to collect and process LiDAR data from different platforms based on real-world experience. The book provides state-of the-art algorithms on how to extract forest parameters from LiDAR and explains how to use them in forest ecology. It gives an interdisciplinary view, from the perspective of remote sensing and forest ecology. Because LiDAR is still rapidly developing, researchers must use programming languages to understand and process LiDAR data instead of established software. In response, this book provides Python code examples and sample data. Sections give a brief history and introduce the principles of LiDAR, as well as three commonly seen LiDAR platforms. The book lays out step-by-step coverage of LiDAR data processing and forest structure parameter extraction, complete with Python examples. Given the increasing usefulness of LiDAR in forest ecology, this volume represents an important resource for researchers, students and forest managers to better understand LiDAR technology and its use in forest ecology across the world. The title contains over 15 years of research, as well as contributions from scientists across the world.

An enormous number of burial objects have been unearthed from ancient tombs in archaeological excavations in China. These mingqi were made in all kinds of materials and in a broad range of forms, techniques and craftsmanship. In this book Quinghua Guo examines a particular type of mingqi -- pottery building. The striking realism of the pottery buildings suggests that they were modelled after actual buildings. They bring to life courtyard houses, manors, towers, granaries and pigsty-privies, as well as cooking ranges and well pavilions. These pottery buildings, previously little known, preserve knowledge of antiquity and demonstrate the architectural quality and structural variety of the period. The author identifies the typology of the pottery buildings they signify in terms of ontology and semiology, in order to provide a conceptual map for classification, and identifies building systems reflected by the mingqi to detect architectonic systems of the Han dynasty. Key features of this volume include: Cross-disciplinary research -- architectural study interlocking with archaeological study; architectural study interlocking with graphic study. The Han pottery buildings are important architectural models from the ancient world, and are contrasted with wooden houses of Middle-Kingdom Egypt and brick buildings of the Minor civilisation, Crete, allowing cross-cultural comparisons.
