| Abstract: | With the development of power industry, the tower foundation section of overhead transmission line obtained through the electric power survey is not only important, but also is the structure of professional tower foundation design reference. The current electric power survey method of the tower foundation section acquisition is introduced with DX＇F encoding format by use of the measured large scale digital tower foundation terrain map, AutoLISP programming the digital tower foundation, and the section automatic extraction method of storage. By extracting the tower foundation section and the actual landform contrast, it shows that the method is reliable, accurate, of high degree of automation, which can meet the design requirements, to make up for the traditional methods of data acquisition of the tower foundation section, and to improve the efficiency of data processing. |
