Abstract: Aiming at tackling the current shortcomings of wide field electromagnetic method data processing software such as low integration, cumbersome operation and inability to manage data in a unified manner, the authors developed wide field electromagnetic method data processing and interpretation software. The software adopts client-server architecture and modular design. The project management module developed based on MySQL database can realize the automatic storage and management of project data. The data processing module of wide field electromagnetic method developed by the scientific computing library based on Python can meet the data processing requirements. Based on visualization and interactive operation, this software can greatly simplify the operation process and improve the efficiency of data processing. This software was applied to actual projects and, as a result, large quantities of data were processed, and good results were achieved.
