Method for obtaining routing inspection in-place data of city pipe network

A method for obtaining routing inspection in-place data of a city pipe network is favorable for improving the data accuracy of the routing inspection in-place rate of the city pipe network, thereby more accurately reflecting the routing inspection work quality and more objectively carrying out routing inspection in-place assessment on the whole pipe network. The method is characterized by including the following steps that a pipeline routing inspection area is determined according to the pipeline map of the city pipe network; mesh division is carried out on the routing inspection area, and a mesh matrix overlapped above the routing inspection area is obtained; an area covered by routing inspection is determined according to the meshes passed by the routing inspection track; the number of the meshes occupied by a certain pipeline in the area covered by routing inspection is determined, and the number is recorded as the length of the routing inspection in-place pipeline; the number of the meshes occupied the certain pipeline in the mesh matrix is determined, and the number is recorded as the total length of the pipeline in the routing inspection area; the routing inspection in-place rate is obtained by dividing the total length of the pipeline by the length of the routing inspection in-place pipeline.
