Currently, the creation of road ledgers and road-based underground facilities uses a fragmentary method that checks whether the drawings created by matching the completed electronic drawings with the written information of each facility are correctly created, so there is a limit in detecting errors in underground underground drawings. . In addition, due to errors in the drawing of underground facilities, additional costs may occur and human resources may be wasted, and drawbacks have been drawn that cannot maintain consistent performance. In addition, most inspection methods have a disadvantage in that they cannot be evaluated in comparison with the situation in the field because they are made only of drawings and documents indoors.

Therefore, there is a need for a method to minimize the error rate through inspection by error type, such as positioning error and structured error, and to maintain consistent performance regardless of the characteristics of the worker and the skill of the operation. In addition, in order to smoothly perform these tasks, there is a need for a method to automatically check whether the rules of various guidelines are well applied to the drawing file of the underground facility, and to automatically correct the errors.
