Wireframes & ZTVs

TNEI’s Technical Team can assist in providing visual representation of wind farms. Wireframes, also known as wire lines, takes into account terrain and turbines dimensions to illustrate the three-dimensional shape of the landscape. They are commonly used to illustrate the expected view from a given location, looking towards the turbines. Wireframes can be drawn at an early stage in the project and are a cost effective visualisation tool.

Zones of Theoretical Visibility (ZTV), also known as Zone of Visual Influence (ZVI), takes into account terrain and turbines dimensions to illustrate the number of turbines that will be seen from any location in the surrounding of a proposed wind farm. Production of ZTVs is usually one of the first steps of Visual Impact Assessments, helping to inform the selection of the study area in which impacts will be considered in more detail.
