海洋地质调查数据是小比例尺下的复杂空间数据,涉及空间二维及三维数据。针对传统属性数据入库管理模式在处理二维及三维海洋地质数据的不足,本文通过对海洋地质调查内容及数据库结构研究设计了一个基于ArcEngine的海洋地质数据入库模型,模型涵盖了属性数据、空间二维数据、三维数据的入库及出库方式。并在广州海洋地质调查局数据库管理系统中得到应用。系统运行良好,保证了数据管理的安全性、稳定性。
Marine geological survey data is a complex spatial data at a small scale, involving two-dimensional and three-dimensional space data. In order to deal with the shortage of two-dimensional and three-dimensional marine geological data, aiming at the problem of traditional attribute data storage management model, this paper designs a marine geological data storage model based on ArcEngine by researching the marine geological survey content and database structure. The model covers attribute data, Space two-dimensional data, three-dimensional data storage and the way out. And in Guangzhou Marine Geological Survey database management system has been applied. The system is running well, ensuring the security and stability of data management.
