Zone of Visual Influence
From Wikipedia, the free encyclopedia
A Zone of Visual Influence is used to identify where a development is theoretically visible from. It is usually represented as a map using color to indicate visibility.
Zones of Visual Influence are used to identify the parts of a landscape that will be affected by a development. They are of particular use to Landscape Architects in determining visual intrusion as part of an Environmental Impact Assessment. Zones of Visual Influence have been used extensively in wind farm development. A map will be created showing the number of Wind Turbine that are visible from a particular area. A cumulative Zone of Visual Influence is used to define the cumulative effects of many developments.
Zones of Visual Influence are created using GIS tools such as ESRIs 3D analyst.
