Abstract: The tracking and analysis of geophysical network data has been fully carried out at stations and central stations, and in the past five years, the effectiveness of the work has gradually become apparent. The event records generated by the tracking and analysis of earthquake precursor data demonstrate the dynamic changes in the observation data of the precursor network, which is beneficial for station personnel to analyze and summarize various events, so that similar problems can be quickly solved in the next encounter. However, in the actual process of data tracking and analysis, some station personnel may have some defects in the production of maps. This article analyzes and explores common problems in selecting mapping time periods, text annotations, missing event recording maps, multi-component measurement item recording maps, earthquake event recording maps, and other common problems in the maps produced by data tracking and analysis, proposes specific methods to solve the problems, and assigns them to practice, Provide useful assistance for station personnel to complete data tracking and analysis research results, and also provide certain reference and reference for encountering other difficulties in work.
