黑龙江省交通数字化中元数据创建问题研究

Research on Heilongjiang Province digital traffic metadata creation

交通信息数据内容繁杂且数据量庞大,建立交通数据元数据是对其进行管理及共享的有效、可行的方法。通过对黑龙江省交通信息数据元数据的现状分析,对已有的元数据标准做必要的改进,重新建立黑龙江省交通信息基础元数据集,使黑龙江省交通信息基础元数据管理和应用更加科学、合理、规范。

Traffic information data vary in content and large in amount. Establishment of traffic metadata is an effective and feasible method to manage and share it. Based on the Heilongjiang Provincial existing traffic metadata status, making some necessary improvements on metadata standards, the paper reestablished the basic traffic information metadata set of Heilongjiang Province, and made the metadata management and application of Heilongiiang Province traffic information more scientific and rational.
