Problems solved by technology
[0004] Routine data processing and graphing require the repeated use of 3 commercial software, and there are a lot of manual calculation and editing work
Each base tower needs to draw 2 tower base section drawings and 1 tower position topographic map. For a 100-kilometer long-distance transmission line project, there are about 200 base tower positions, and a total of about 400 tower base section drawings and 200 A topographic map of the tower position, the workload is particularly heavy, and error-prone

The invention discloses a data processing and mapping method of topographic surveying of electric transmission line tower positions. The data processing and mapping method comprises the following steps of 1) system initial parameter setting; 2) engineering information inputting; 3) engineering data inputting; 4) data processing; 5) data calculation processing; 6) tower base cross section and tower position topography mapping; 7) data storage; 8) result data incidence relation building; and 9) data outputting. The data processing and mapping method realizes the automatic analysis of the tower base cross section and the computer aided design point, the automatic contour line building and the topographic map generation. The data processing and mapping method is generally applicable to the tower position data collection and processing work in the electric surveying design industry, the data structure and the function design have good popularization value, and the mapping work efficiency and the accuracy rate can be respectively and greatly improved in the practical application.
Description
technical field [0001] The invention relates to a method for automatically drawing a tower position topographic map and a tower base sectional view by using tower position topographic measurement data collected by a total station and GPS for the field survey of a power transmission line, and belongs to the technical field of engineering surveying in the surveying and mapping discipline. Background technique [0002] According to the design requirements of the transmission line project, the topography of the tower position is measured, and the topographic map of the tower position and the cross-sectional view of the tower base are drawn through the measured data, which are used as important basic data for the design of the tower structure. [0003] The National Standard of the People's Republic of China "Specifications for the Survey of 330kV~750kV Overhead Transmission Lines" (GB50548—2010) regulates the surveying and mapping requirements in this area. Section 6.9 of the regu...
