| Abstract: | Based on geomagnetic data for earthquake prediction, the process of application of geomagnetic data is studied. According to the process and specifications, the frequency spectrum analysis system of geomagnetic data based IDL and DataMiner is designed and implemented. Separating the data processing and the result displaying not only simplified the development of the system, but also improved the expansibility and maintainability of the system, and improved the display effect and the user experience. |
