Research on Great Wall section protection and user VR experience innovation based on GIS data visualization

VR technology can enable users to be in a realistic virtual environment, thus bringing them an immersive experience. It has great charm and can effectively display scenes that are difficult to reproduce in real life. It can also be used in education and other fields. It has a wide range of applications and can bring great convenience. Under this background, this paper introduces GIS data visualization technology to complete the expansion of VR technology and apply it to the Great Wall section protection research project. This paper has improved a kind of VR system, which can meet the needs of human–computer interaction and create virtual avatars to achieve two-way communication between human and VR experience environment. This system design has the advantages of simple use and powerful functions and is also the design goal of VR experience technology itself. The ease of use of the system is reflected in the visual clarity of interface interaction and system response speed. The practicality is reflected in the stability of system operation and the time required for users to complete feature functions. The security is reflected in the degree of protection of private data. The simulation results show that the system can effectively reduce the magnitude of data after processing and compressing the data set, thus reducing the processing time. Compared with the original processing method, it can be seen that the system improves significantly. By traversing the original dataset, the array can be effectively drawn, which greatly reduces the system processing time and improves the efficiency. In this paper, GIS data visualization technology and VR technology are integrated to complete the research of the Great Wall section protection project.
