【摘要】：在地学领域中，通过地学模型模拟现实世界，应用地学分析提供事务处理方案，用以解决现实问题，，已经成为了地学研究中的一种常用方法。由于地学空间数据具有多源性、多领域、多尺度、数据量大、共享性强并且具有拓扑特征等特点，对地学空间数据进行合理地存储和管理，成为该方法的基础。因此，对多源地学空间数据进行存储、管理和应用的重要性就显而易见。论文以辽宁省兴城地区的地学情况为数据参考，对建立多源地学空间数据库的相关理论和关键技术进行了研究。本文以辽宁省兴城地区为研究区，首先分析了研究区的地学情况，对地学空间数据及其特点进行了总结，对各种空间数据模型进行了优缺点的比较，重点对应用Geodatabase空间数据模型和ArcSDE技术构建多源地学空间数据库管理系统进行了分析,主要包括数据库建立模式与系统框架构成。该系统以Geodatabase空间数据模型为基础，利用SQL Sever作为数据库平台，应用ArcSDE空间数据引擎和GIS二次开发技术，实现了多源地学空间数据的存储、检索、管理和输出等功能。最后，以兴城地区的地学空间数据为例，对多源空间数据库管理系统的应用进行了简单的演示。多源地学空间数据库的建立对地学空间数据的集中存储和统一管理进行了尝试，多源地学空间数据库管理系统的实现对应用地学数据研究现实问题提供了良好的平台，具有重要的现实意义和应用价值。
[Abstract]:In the field of Geoscience, the real world is simulated by the geoscience model, and the application of geoscience analysis provides a transaction processing scheme to solve practical problems. It has become a common method in the study of Geosciences. The spatial data of Geosciences are stored and managed reasonably. Therefore, the importance of storing, managing and applying the spatial data of multi source geography is obvious. The paper takes the geoscience of Xingcheng area of Liaoning Province as the data reference, and carries out the related theories and key technologies for the establishment of a multi source Geoscience database. The study.
This paper, taking Xingcheng area of Liaoning Province as the research area, first analyzes the geoscience situation in the study area, summarizes the geoscience spatial data and its characteristics, compares the advantages and disadvantages of various spatial data models, and focuses on the construction of the multi source geoscience spatial database management system using the Geodatabase spatial data model and the ArcSDE technology. Based on Geodatabase spatial data model and SQL Sever as the database platform, the system uses the ArcSDE spatial data engine and the two development technology of GIS to realize the storage, retrieval, management and output functions of multi source spatial data. Finally, Xingcheng As an example, the application of multi-source spatial database management system is demonstrated.
The establishment of multi source geoscience spatial database has made an attempt at the centralized storage and unified management of geoscience spatial data. The realization of the multi source geoscience spatial database management system provides a good platform for the practical problems of Applied Geoscience data research, and has important practical significance and application value.
