This paper concisely introduced the basic condition of Google Earth, elaborated its advantages and disadvantages for using with a utility patrolling system. In order to make u Pthe shortcoming of Google Earth and satisfy the request of pipeline inspection system, this paper introduced the thought that Google Earth can be superimposed by the image data and the fundamental geographic data. It introduced the principle and technology in detail and explained the use method. Taking Deyang as an example, the method was realized Finally it proposed several problems during the commercial development of Google Earth.
