Unmanned Aircraft Systems (UAS) LiDAR (Light Detection and Ranging) survey technology, has been widely used in the survey and design of overhead transmission line projects benefiting from its high precision and efficiency, especially for high-voltage overhead transmission lines in complex terrain areas. To standardize the operation process of UAS LiDAR survey and meet the requirements of survey and design for overhead transmission line projects with a voltage level above 110kV, this standard specifies the technical requirements for various production stages, including the composition of UAS LiDAR systems, flight design and implementation, data processing, 3D (three-dimensional) digital surveying and mapping, field investigation and survey, and 3D digital design. It is applicable to guide the survey of the light and small civilian UAS LiDAR in the survey and design of new and reconstructed overhead transmission line projects and as the reference of the construction, operation, and maintenance, etc.

UAS in combination with LiDAR are effective in DEM generation and land use survey, which are important for transmission lines design. This standard specifies the operational requirements for the workflow, procedure, technical parameters, and quality control of the UAS using LiDAR for above 110 kV overhead transmission line survey and design.
