New remote sensing techniques, such as airborne laser scanning (LiDAR), have led to a dramatic increase in terrain information, providing new opportunities for landform analysis. A major advance in using LiDAR‐derived high‐resolution topography (HRT) is the capability to provide an accurate and detailed terrain morphology. This study aims to use LiDAR HRT to identify palaeochannels of the Manawatu River (New Zealand) using an automated procedure based on the statistical analysis of landform curvature. The approach can provide rapid assessment and classification of floodplain topography. The proposed analysis is crucial, especially for intensively used floodplains requiring effective flood management and mitigation.

Manawatu古河道的高分辨率映射

机载激光扫描（LiDAR）等新的遥感技术导致地形信息急剧增加，为地貌分析提供了新的机会。使用LiDAR衍生的高分辨率地形（HRT）的主要进步是能够提供准确而详细的地形形态。这项研究的目的是使用LiDAR HRT通过基于地形曲率统计分析的自动化程序，识别Manawatu河（新西兰）的古河道。该方法可以提供洪泛区地形的快速评估和分类。提出的分析至关重要，特别是对于需要有效管理和缓解洪水的密集使用的洪泛区。
