To improve the efficiency and accuracy of power data generation

a study on the 3D line selection and mapping platform system for multi-source data is carried out

aiming to achieve efficient 3D mapping and line selection and meet the requirements of power engineering for geographical information analysis and result output.The system supports the import of multi-source data

including orthophotos

vector data

oblique data

real-scene 3D models

and laser point clouds.It precisely depicts the contours

positions

and geometric relationships of spatial objects of interest through points

lines

and polygons

and scientifically organizes attribute data

combining it with spatial feature data to comprehensively describe geographical entities and their interconnections.With the above methods

the system successfully realizes the function of 3D mapping and line selection

and can batch generate power data results such as tower base topographic maps

tower base cross-section maps

and route maps.The results demonstrate that the 3D line selection and mapping platform system for multi-source data

it provides an efficient and accurate solution for generating data results in power engineering

and has significant practical value and application prospects.
