1 Scope
This standard is established to specify the principles, precision indicators, job methods and technical requirements when using aerial survey line selection technology, aerial survey digital survey technology and Global Positioning System (GPS) to survey overhead transmission lines.
This standard applies to the aerial aerotriangulation work during survey and engineering stage of newly-built overhead transmission line projects at 110 kV and above.

3 General
3.0.1 This standard is established to meet the needs for development of analytical aerotriangulation technology for overhead transmission lines (abbreviated as line aerial survey), unify the technical standards,maintain technically advanced, provide accurate survey materials for construction of overhead transmission line projects and meet the requirements for designing transmission lines so as to optimize the lines route and reduce construction costs.
3.0.2 In order to keep pace with the design stage, the survey stage for overhead transmission line projects shall be divided into the survey in the preliminary design stage (abbreviated as preliminary survey) and the survey in the construction drawings design stage(abbreviated as final survey).
3.0.3 The surveying instruments and tools for both office and field work of aerial survey must be timely inspected and calibrated,periodically repaired as well as maintained and serviced carefully.
3.0.4 The original records of handbooks (including electronic handbooks) for office and field work shall be authentic, legible and complete. Any erasing, obliteration, transcription and supplement afterwards is strictly prohibited.
3.0.5 In addition to this standard, the aerial survey of lines shall conform to the applicable provisions of GB 50167, DL 5001 and CH2001 as well.
