摘要:
地形地貌是影响公路选线的核心因素之一，传统的地貌类型的划分方法过分注重地貌单元的完整性，缺乏有效的针对地貌实体对象的自动提取. 以规则格网数字高程模型为数据源，利用数字地形分析中的地形特征和水系特征等提取技术，提出一种公路选线中地貌实体单元的自动提取方法. 该方法与结合专家知识的人工提取结果吻合，实现了自动划分山地与平原、自动提取嵌套山体界线. 在开展公路初步选线的过程中考虑山体的完整性，相比仅考虑地貌微观因子的选线方法，得到了较好的结果.
Abstract:
Landform is one of the key factors affecting highway route selection. Considering the integrity of topographic entity is of great significance in highway route selection. The traditional classification of landform types focuses on integrity of the entity unit of landform，and lacks an effective method for automatic extraction of geomorphological entity unit. Aiming at solving this problem，this paper puts forward a method for extracting terrain entity unit by using digital elevation model (DEM) as data source and the related extraction technologies of terrain and water characteristics in digital terrain analysis. This method realizes the plain/mountain automatic extraction and the automatic division of nested mountain boundary. The experimental results show that the method is accordant with the results of manual extraction combined with expert knowledge，and thus achieves the automatic division of plain/mountain areas and the extraction of nested mountain boundaries. Furthermore，considering the integrity of mountain in the process of initial highway route selection, we get better results compared with the route selection method only considering the microscopic topographic factors.
