地磁信息系统的设计与实现

The Design and Realization of China Geomagnetic GIS

以中国地磁信息系统(CGGIS)研制为例,探讨了其管理和分析的可行性。结果表明,地磁GIS系统,不仅能够有效地管理海量地磁相关数据,而且,可方便直观地再现地磁观测数据,有效地整合地磁相关空间数据并且充分地发掘地磁场变化规律.是一种值得进一步深入研究和应用的空间型地磁信息系统。介绍了系统的网络结构、总体结构和功能结构设计以及系统特色功能(如地磁测点点志记功能、测点辅助设计功能,地磁模型成图功能等)。

This paper explores the feasibilities of applying GIS to the management of geomagnetic related information, taking the design and realization of the China Geomagnetic Geographic Information System (CGGIS) as an example.It introduces the brief design process, including the network structure, logical structure and functional structure of the system. It also describes some of the key functions that have been successfully realized, such as the E-card function of the geomagnetic observation station, the GIS aided location design function of the geomagnetic observation stations, and the geomagnetic model visualization function, etc.The result shows that the database and its application system based on GIS technology not only can manage the related geomagnetic chart data of sea-amount efficiently, but also can be helpful to present the obtained geomagnetic data expediently and directly, integrate the related spatial data efficiently and discover the hidden laws concerned the geomagnetic field. Such a Spatial Enabled Geomagnetism Information System (SEGIS) deserves further research and application.
