摘要
大量新模型新算法的不断涌现,使自动制图综合经过40余年的发展取得了长足的进步。但随着研究的深入,许多学者已经认识到,缺少自动综合的质量控制机制,是不能实现真正意义上的自动综合的,但目前的状况是,多数自动综合工具除了能给用户提供基本的参数设置外,尚不能控制综合的质量。因此,在分析自动综合目前存在的主要问题的基础上,通过对自动综合质量评估研究现状的深入剖析,提出了地图自动综合质量分析与评价标准建立所需的主要研究内容及研究思路。
With many new algorithms and new models coming forth, automatic cartographic generalization has made quite great progress in the past 40 years. As some experimental systems and a spot of commercial systems have contained some functions of automated generalization abroad, some software for automated generalization has been developed and used in China. But with in-depth study on this aspect, many scholars have realized that the automated generalization can＇ t be achieved actually without quality control mechanism. Most automated generalization tools only provide basic parameter settings but can＇ t control the quality of generalization at present. Therefore, on the basis of analyzing primary questions of automatic generalization at present, via embedded anatomy of current research status of automatic generalization quality assessment, main research contents and ideas needed for developing quality analysis and evaluating criterion of automatic map generalization are proposed.
