The distance of human transportation is an important factor affecting the cost of transmission line engineering.Cost engineers usually measure each tower position on the image map to calculate the average transportation distance.This method is inefficient and has more human factors.This article is based on ArcGIS for secondary development

where transportation roads are made into vectorized data.Based on the already loaded route plan and design information in GIS

the distance calculation of tower positions is quickly achieved.This method is not only fast and accurate in calculation

but also has a high degree of visualization

which can be used as a reference for engineering budget estimation and cost analysis.
