摘　　要：全空间信息系统中,多粒度时空对象建模最终成果主要分为多粒度时空对象交换格式数据和多粒度时空对象数据库数据两种形式。对比分析了两者对多粒度时空对象的组织和存储方式,探讨了对象数据入库流程,设计并实现了基于规则的多粒度时空对象入库方法。该方法主要有两点优势:1)实现了入库工具与源数据格式及目标数据库结构的解耦、减少了编码工作量;2)为应对后续多粒度时空对象建模理论的演进与发展提供了灵活而强大的扩展机制。实验表明该方法为多粒度时空对象数据入库提供了一个可行的解决方案。In pan-spatial information system, the final results of multi-granularity spatio-temporal object modeling are mainly divided into two forms: multi-granularity spatio-temporal object exchange format data and multi-granularity spatio-temporal object database data. This paper compares and analyzes the storage contents and organization forms of these two, probes into the data loading process of the objects, designs and implements a rule-based data loading method for multi-granularity spatio-temporal object. The two main advantages are as follows: 1) Decouples the data loaders, the source data and the target data table structure and greatly reduces the amount of coding work. 2) Provides a flexible and powerful extension mechanism for dealing with the change and development of multi-granularity spatio-temporal object modeling theory. Experiments show that this method provides a feasible solution for multi-granularity spatio-temporal object data loading.
