Automated mapping of visual impacts in utility corridors

Abstract It is widely recognized that linear utilities such as overhead electricity transmission lines have a significant effect on the visual environment. Assessment of aesthetic values along the entire length of a utility corridor is often impractical. The large area of potential impact increases problems of inconsistency and non-repeatability. This paper presents an approach to automated mapping of the visual impacts in utility corridors. Using transmission lines as an example, the system takes account of complex relationships between the transmission structures, the environment and the observer. With further testing and calibration of these relationships the system will be capable of application on a routine basis.
