The web-based gravity and magnetic grid grid data processing tool and its implementation

云计算为地质行业软件提供了新的发展方向,笔者采用云计算技术,研发了一个基于web的在线重磁网格数据处理系统,使得用户无需安装即可便捷获取滤波、延拓、导数计算等数据处理功能。该工具采用了三层架构设计,分别为展现层、计算服务层和逻辑控制层。其中展现层利用web2.0前端技术开发,提供用户交互界面及数据可视化功能。计算服务层封装了一系列网格数据处理算法,用于处理用户提交的数据处理任务并返回数据处理结果,该层包括滤波计算、频率域向上延拓方法和差分迭代向下延拓算法等。逻辑控制层连通展现层和计算服务层,根据用户提交的数据处理请求调用所需算法并返回计算结果。我们利用RGIS软件对比检验了系统可用性,通过不同计算平台对比,验证了系统的跨平台适应性。

Cloud computing provides a new development direction for the geological software. The authors have used cloud computing technology to develop a web-based online grid data processing system that allows users to easily obtain data processing capabilities such as filtering, extension, and derivative calculation without installation. The tool uses a three-layer architecture, namely the presentation layer, the logic layer, and data processing service layer. The presentation layer is developed using web 2.0 front-end technology to provide user interaction interface and data visualization functions. The data layer encapsulates a series of grid data processing algorithms, which are used to process data-processing tasks submitted by users and response data processing results. This layer includes filter calculation, frequency domain upward continuation method, and differential iterative downward continuation algorithm and some other means. The logic layer connects the presentation layer and the data layer, and calls the required algorithm and returns the calculation result according to the data processing request submitted by the user. The authors tested the correctness of the tool using magnetic data from a synthetic model, and verified the cross-platform convenience of the tool by comparative study of this means on different computing platforms.
