Abstract: Due to the particularity of electric power engineering surveying and mapping, the traditional production mode of electric power engineering surveying and mapping is separated from the internal and external work, which has repetitive labor and low efficiency. To solve this problem, this paper is based on Trimble GNSS system puts forward a new solution, develops a set of internal and external integrated operation system, solves technical problems such as data communication at different equipment ends, unified coding of ground object attributes, base map loading and sketch drawing, and can easily collect survey data and ground object attributes in the field, and automatically generate CASS, DH field operation code files and relevant reports. Through field engineering test, the system not only saves a lot of time, manpower and material resources, but also is intuitive and easy to use, not easy to make mistakes.
