Abstract: This paper introduces the GIS technology to seek the application in the reconnaissance and survey of pipeline route. The GIS applied system is consisted of hardware technology, software function and geography-space data. The authors consider that incorporating the GIS technology with GPS technology not only utilizes the latest information in reconnaissance and survey of pipeline route, but also avoids some occurrences due to the way missed with the guiding function of the combined technology. In addition, the GIS technology can also be utilized in the reconnaissance and survey of pipeline route and pre-engineering design including the statistics and analysis of data as well as drawings output of pipeline route.
