| 摘 要： | 要提高自动综合的自动化水平,不但要开发自动化、智能化程度高的自动综合算法,同时需要对自动综合算法进行有效地管理和使用。目前国内外研究重点在于前者,而对后者研究较少。本文提出了自动综合算法元数据的概念,并从自动综合算法的适用范围、算法功能、算法参数等关键信息,以及算法基本信息、经验信息、改进信息和综合评价指标等辅助信息,以及自动综合算法优先权等方面着手,分步骤、分层次地设计并构建了自动综合算法的元数据管理体系,从而实现了方便、有效地管理与调用自动综合算法,为提高自动综合的自动化程度和水平提供了有力支持。

| Abstract: | In order to improve the automatization of map generalization, we should not only develop more advantage automatic generalization algorithms, but also manage and use these generalization algorithms effectively. However, most researches now are still in the first space, and we seldom touch the aspect of algorithm management. This paper put forward a new concept termed "metadata of automatic generalization algorithm", and designs and establishes the automatic generalization algorithm metadata based on key items of map use, algorithm operation, algorithm parameters, and assistant items of algorithms basic information, experience information, improvement information and integrate assessment criteria etc. This kind of metadata is vital and more convenient to manage and use automatic generalization algorithms, and makes greater supports to improve automatic generalization automatization and level. |
