【摘要】：随着地理信息系统正在以极速扩张的趋势应用于各个领域，，地理信息系统对空间信息技术的应用需求逐渐增大，空间数据的储存、读取成为各种行业领域应用地理信息系统的基础。面对地理信息世界里多源、海量的空间数据，寻求一种合理的数据组织和综合方式，使之形成一种整体化、综合化的空间信息综合服务网络，实现多源、海量数据集成和管理系统，成为各行业业务新的需求，研究与开发一种实用而又有效的数据管理系统一直是地理空间信息的一个重要课题。可靠、稳定、高效的数据管理系统可为行业部门、地方的应用提供高效、稳定、可靠的数据产品服务和技术支持。本文通过对基于开源GIS的多源数据管理系统的研究，紧密结合863项目“国家统计遥感业务系统关键技术研究与应用”实例，自主开发基于GDAL/OGR和以PostgreSQL为空间数据库的多源数据管理系统，对矢量数据、栅格数据和表格数据存储方法进行了研究。综上所述，本文对多源数据管理系统的开发和研究，主要包括以下方面：（1）总结了研究的背景和意义，并对数据库管理系统的国内外研究现状作了分析比较。（2）进行需求分析和总体设计。按照标准化与规范化的要求建立逻辑上和物理上无缝的多源数据库。（3）设计多源数据管理系统。系统基于GDAL/OGR架构模块，每个模块以dll或exe形式存在，利用面向对象的方法将这些模块集成形成多源数据管理系统。（4）剖析系统开发中的关键技术。包括GDAL/OGR、PostGIS理论技术，以及系统开发中的特色技术，如分布式存储技术、多数据库相结合技术，以及数据存储方法等。（5）开发并实现多源数据管理系统。将以上三部分的设计和思想集成为一个有机整体，形成基础地理空间数据管理系统。最后，通过运行实例证明这种解决方案的可行性。
[Abstract]:With the rapid expansion of geographic information system (GIS) in various fields, the application of GIS to spatial information technology is gradually increasing, and the storage of spatial data. Reading has become the basis for the application of GIS in various industries. In the face of the multi-source and magnanimous spatial data in the geographic information world, we seek a reasonable data organization and synthesis way to form a kind of integrated and integrated spatial information integrated service network to realize the multi-source. Mass data integration and management system (MMS) has become a new requirement of various industries. The research and development of a practical and effective data management system has been an important subject of geospatial information. Reliable, stable and efficient data management system can provide efficient, stable and reliable data products, services and technical support for industry departments and local applications. Based on the research of multi-source data management system based on open source GIS, this paper closely combines with the example of 863 project "Research and Application of key Technologies of National Statistical remote Sensing Business system". A multi-source data management system based on GDAL / OGR and PostgreSQL is developed. The storage methods of vector data raster data and tabular data are studied. To sum up, the development and research of multi-source data management system in this paper mainly include the following aspects: 1) summarize the background and significance of the research. The present situation of database management system at home and abroad is analyzed and compared. According to the requirements of standardization and standardization, a logical and physical seamless multi-source database is established. A multi-source data management system is designed. The system is based on GDAL / OGR architecture module, each module exists in the form of dll or exe, and integrates these modules into multi-source data management system by object-oriented method. Including the GDAL / OGRG PostGIS theory technology, and the characteristic technology in the system development, such as distributed storage technology, multi-database combination technology, and data storage method, etc. 5) develop and implement multi-source data management system. The design and thought of the above three parts are integrated into an organic whole to form the basic geospatial data management system. Finally, the feasibility of the solution is proved by a running example.
