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.

      However, conditions are seldom that clear and vary though each day. To map reduced visibility impacts, following Hadrian et al. (1988), the downward slope of the line of decrease with distance was increased. This had the effect of reducing both the impact of each turbine, by increasing amounts at larger distances, and the distances at which their impacts reached zero.

      It is explained that the visibility of a landmark decreases exponentially by raise of the distance between the observer and the object. To be more precise, the visual impact of the distance of 1000 m diminishes to 25 % in comparison to 500 m distance and decreases drastically to 10 % when the object is 2000 m away (Hadrian, Bishop, & Mitcheltree, 1988; The World Bank, 2007). Some scholars have tried to include the distance impact by defining weighting options (Domingo-Santos et al., 2011; Wagtendonk & Vermaat, 2014).

      This is not to say that researchers have not investigated landscape assessment approaches. For example, Hadrian, Bishop and Mitcheltree (1988) present an approach to using a GIS to assess visual impacts that included the effect of viewing distance and visual magnitude, as well as a number of other features. However, these examples were not adopted by practicing landscape architects and the reasons for this have gone unexamined.

      Visual impact assessment is the relatively straightforward process of describing the visual characteristics of a proposed project, determining its visibility in the surround landscape, and describing the visual magnitude of the project as seen from various viewpoints. The general process for conducting this analysis has been understood for decades (Hadrian, Bishop, & Mitcheltree, 1988). The analysis may be extended to describe the visual contrast of the project with the existing landscape (BLM, 1986b).
