地图数据图层级批量综合功能的设计与研制

目前,已有地图综合系统使用过程中需要专业人员深度参与,耗时耗力、自动化程度较低。针对这一问题,从软件工程的角度探讨了图层级批量综合功能的研制。以1∶5万居民地图层数据的综合处理为例,分别从建筑物目标的剖分、特征参量定义与计算、综合操作决策与实施、综合控制规则建立与表达4个方面进行分析,尝试构建"特征诊断→行为决策→操作执行"的完整技术链条。结合样例数据对提出的技术设想进行可行性验证,并对后续工作进行展望。

An Exploration on Design and Development of Layer-Level Automatic Map Generalization

Currently, deep participation of cartographers is demanded in the existing map generalization systems. The process is time-consuming and labor-intensive. To address this problem,we explore the design and development of batch integrated automatic generalization at layer-level. Taking the 1:50 000 generalization of layer data of residential areas as an example, an analysis is conducted from four aspects including the classification of building objects, the definition and calculation of feature parameters, generalization decision making and implementation, and the establishment and expression of generalization rules to build a complete technology chain of "feature recognition, decision making, and operation implementation". And the sample data is applied to verify the effectiveness of the proposed method and the future work is also discussed.
