摘要
针对多年份地理国情数据包括多种细分类型数据,且各年份数据标准不完全一致的问题,设计了一种地理国情监测数据库管理系统。通过构建地理国情时空数据模型,利用时间轴管理和展示多年份地理国情数据;通过搭建变化统计分析子系统进行地理国情信息的快速统计和报告制作,大幅提升了地理国情数据的管理和应用水平。研究结果表明,时空数据模型可实现标准有差异的多版本地理信息数据的统一管理,该系统能实现对时空数据的智能化管理、展示以及统计分析等功能。
The multi-year geographical nation data includes a variety of subdivision types, and the data standards of each year are not completely consistent. Aiming at these problems, we designed a set of geographical conditions monitoring database management system. This system used the time axis to control and demonstrate data based on the establishment of geographical nation spatio-temporal data model, and carried out rapid statistics and report production of geographical nation information by the construction of change statistical analysis subsystem, which could dramatically promote management and application level. The results indicate that versions of geographical information data with different standards can be controlled uniformly with the spatio-temporal data model, and the intelligent management, presentation and statistical analysis can be realized by means of the software development system.
