15 صفحه اولTree Crown Mapping in Managed Woodlands (Parklands) of Semi-Arid West Africa Using WorldView-2 Imagery and Geographic Object Based Image Analysis
Detailed information on tree cover structure is critical for research and monitoring programs targeting African woodlands, including agroforestry parklands. High spatial resolution satellite imagery represents a potentially effective alternative to field-based surveys, but requires the development of accurate methods to automate information extraction. This study presents a method for tree crow...
متن کاملRetrieving Tree Heights in African Savanna Woodlands Using Three Stage
African savanna woodlands have an unpredictable spatial and temporal variability of woody biomass densities as a result of the interplay of rainfall, soil nutrients, fire, people and herbivores. These woodlands are characterised by heterogeneous species distribution with irregular vertical structures. A large percentage of rural communities in southern Africa rely on communal woodlands to meet ...
