Generally, professionals analyze the map data, a professional product is difficult to form, the general map data is large in data volume, and if the general map data is not analyzed, the most critical part for the service usefulness is how to analyze and apply the large data.
By taking attack situation data in a map as an example, in recent years, network security events are layered endlessly, and types and means are diversified, so that great difficulty is brought to network security supervision. How to make the mass data detected in real time, quickly summarized and accurately analyzed into data with practical value, and realize map visualization according to access attack data, and better interactive operation is realized.
Data display based on a map often cannot realize diversified utilization of data, only few data can be displayed one by one, and a large-screen display effect is realized. The operation of a user on data analysis and data integration is little, on the other hand, a huge database is accumulated, but the data size of a platform is large due to the detail of data division, the interface is relatively poor, and due to the complexity and high operation cost of the user, the user needs to spend a lot of time for monitoring, viewing, analyzing and managing data, but the user cannot respond to the requirement of the user in time, and finally the limitation is limited.
For a more sophisticated map operation, if the user operates in a larger map area and there is too much data, the data state on the map is very dense, which may result in the user not being able to clearly see the information. Only a specific area can be enlarged on the map. Existing interaction operations can only move maps, or search and locate, continuously if it is desired to move to other areas. Such interaction will undoubtedly increase the user's operation steps.
