The data processing unit 302 sets different priorities according to the importance levels of survey marks, the database classification unit 303 stores survey mark information in different databases according to different navigation routes, and the survey mark information is sequentially arranged in the database classification unit 303 according to the priority levels of the physical shape information.
It should be noted that, when the data processing unit 302 analyzes the physical shape information of the exploration point and determines the processing priority of the exploration point, the main influencing factors include the three-dimensional volume of the exploration point, the coordinate position of the exploration point, and the influence on road traffic.
According to the above, the invention not only simulates the survey information in real time to generate the survey map in the two-dimensional or three-dimensional direction on the navigation route, but also performs centralized comparative analysis on the survey information, decomposes the survey information from the two-dimensional or three-dimensional direction, summarizes the influence of the survey information corresponding to each survey point on the road, so that the survey mark information is sequentially arranged in the database classification unit 303 according to the influence degree, the survey points arranged at the upper end of the database need to be preferentially processed, and then the survey mark information which does not pass is sequentially processed, thereby facilitating the dispatching of the survey object processing sequence in the road planning by the staff, improving the working efficiency, and facilitating the regulation and control of important information such as planning time, planning cost and the like, so the navigation system plays a role in putting a light weight on the whole road survey planning.
Based on the above, in the embodiment of the invention, the main operation of using the road planning navigation system is divided into the following steps;

then, the user carries out on-site and on-site investigation on each navigation route respectively, and sends the position information and the physical information of the exploration point to the simulation operation terminal 3 in real time;
and finally, the simulation operation terminal 3 carries out background editing on the navigation route, and matches the position information and the physical information to the navigation route at fixed points to generate the navigation route with the reconnaissance marking map.
Based on the GIS geological information system 102 and the GPS navigation system 101, at least 2 survey routes are selected from the starting point to the end point in the area to be planned, that is, a plurality of planned path schemes are provided by combining the power grid information and the GIS technology, and each path scheme is surveyed on the spot, so that the planned scheme is determined.
