制图综合知识及其应用

Cartographic-generalization-knowledge and Its Application

阐述了制图综合知识的概念、结构和组织方法,提出了基于制图综合知识的综合任务提取、综合算法与结果的评估、综合操作监控以及基于知识的制图综合任务存储等原理和方法。实验表明,制图综合知识的使用,对制图综合各个环节的评价提供了依据,对综合自动化程度的提高有着重要的推动作用。

Cartographic generalization-knowledge （CGK） is vital in the whole process of automatic cartographic generalization. Three main steps were introduced in the following.First, the concept and structure of CGK were defined, and its organization method was given. Second, methods of mining generalization tasks, monitoring user＇s operations and how to assess generalization algorithms and results based on CGK were put forward. Finally, the theory and technique of saving generalization tasks were involved. The experiment demonstrates that CGK is important in cartographic generalization. CGK provides a basic reference for the assessment in generalization.
