【摘要】：地理信息的自动综合是数字环境下地图学与GIS的国际性难题之一。传统基于数学模型的综合方法由于无法描述地图综合中大量的模糊性问题,所以无法全面解决地图自动综合问题。多要素协同综合思想的提出,在一定程度上减少了综合后要素间的冲突问题,但现有关于多要素协同综合的研究,多集中在某些特定区域类型或分布特征的地区,尚无较为全面的多要素协同综合解决方案。自然环境下的等高线与河网在地理成因上相辅相成,具有天然的耦合关系,因而成为协同综合研究的首选。随着计算机、人工智能技术的发展,Agent所具有的自我工作和思维能力,能够模仿地图综合专家的思维过程,提高地图综合的自动化水平。但由于现有等高线与河网地图综合知识的“深度”和“广度”不够,制约了其智能化综合的发展。将汇水区域纳入到协同综合范畴之中,将有利于进一步统一等高线与河网的结构化综合。并且汇水区域内部等高线与河流空间关系较为简单,能有效的降低冲突问题的复杂性。为了实现本文提出的智能协同综合方法,首先总结了现有等高线与河网的协同综合知识,使用汇水区域边界作为等高线与河网协同综合的约束条件,将汇水区域作为协同综合的最小单元,针对不同类型汇水区域设计了不同的综合方法。在此基础上分析了汇水区域约束下等高线与河网智能协同综合的Agent分类,给出了各个综合Agent的属性与行为。然后对本文提出的汇水区域约束的协同综合方法进行了形式化表达,提出了汇水区域约束下等高线与河网的智能协同综合模型。最后基于JADE开发了地图多要素智能协同综合系统MAPGen,并做了试验验证。通过分析实验结果,证明了本文提出的智能协同综合方法,能够很好的保持多尺度综合后等高线与河网的各种空间与语义关系,有效避免了综合后地图目标之间的冲突。
[Abstract]:Automatic synthesis of geographic information is one of the international problems of cartography and GIS in digital environment. Because the traditional mathematical model based synthesis method can not describe a large number of fuzzy problems in map synthesis, it is unable to solve the problem of map automatic synthesis in an all-round way. The idea of multi-factor synergy synthesis reduces the conflict problem among the elements after synthesis to a certain extent. However, the existing research on multi-factor synergy synthesis is mainly focused on the areas with certain regional types or distribution characteristics. There is no comprehensive multi-factor cooperative solution. The contour line and river network in the natural environment complement each other in geographical origin and have natural coupling relationship, so they become the first choice of collaborative synthesis research. With the development of computer and artificial intelligence technology, Agent has the ability of self-work and thinking, which can imitate the thinking process of map synthesis experts and improve the automation level of map synthesis. However, the existing contour map and river network map synthesis knowledge "depth" and "breadth" is not enough, which restricts the development of its intelligent synthesis. Bringing the catchment area into the category of synergetic synthesis will help to further unify the structural synthesis of contour line and river network. And the relationship between the contour and the river space is relatively simple, which can effectively reduce the complexity of the conflict problem. In order to realize the intelligent cooperative synthesis method proposed in this paper, firstly, the existing knowledge of collaborative synthesis between contour lines and river networks is summarized, and the boundary of catchment area is used as the constraint condition for the collaborative synthesis of contour lines and river networks. Taking the catchment area as the minimum unit of collaborative synthesis, different synthesis methods are designed for different types of catchment areas. On this basis, the Agent classification of intelligent cooperative synthesis of contour line and river network under the constraint of catchment area is analyzed, and the attributes and behaviors of each synthetic Agent are given. Then, the collaborative synthesis method of catchment region constraints proposed in this paper is formalized, and the intelligent cooperative synthesis model of contour line and river network under catchment area constraint is proposed. Finally, the map multi-element intelligent cooperative synthesis system MAPGenbased on JADE is developed and tested. By analyzing the experimental results, it is proved that the intelligent cooperative synthesis method proposed in this paper can maintain the spatial and semantic relationships between contour lines and river networks after multi-scale synthesis, and effectively avoid the conflict between map targets after synthesis.
