SPECIALIST SURVEYING FEATURE NAVITUS BAY CASE STUDY
environment. Viewers were able to toggle between different turbine sizes layouts and follow the proposed cable route from the wind turbines to a substation at Three Legged Cross near Ringwood.
THE RESULT The model was used
extensively throughout the third phase of public consultations which took place at eight locations along the coast. Around 2,000 visitors attended the exhibitions and they all had the opportunity to use the 3D model to assess realistic views of the wind farm from any requested viewpoints which would otherwise have been impossible to provide.
THE CHALLENGE the Navitus bay wind park, a joint venture between Eneco Wind UK Ltd and EDF Energy, has recently completed the third phase of stakeholder and public consultation. The proposals are for between 136 and 218 offshore turbines in poole Bay at a distance of at least 14 km from the coast.
As always on such schemes, Navitus bay faced a challenge to effectively communicate the appearance of the development when viewed from different locations along the coastline. There was some debate about the
efficacy of traditional photo montages and the number of views that could be offered.
So, the Navitus bay team turned to 3DW, a Manchester based company who specialise in creating interactive 3D computer models of wind farm developments to address visual impact issues in a dynamic and engaging format. To date, the company has produced 3D models to support over 75 on and offshore wind farm projects.
THE SOLUTION Using a combination of ordinance Survey terrain data, aerial imagery, mapping data and over 1,000 local photographs, 3DW created a fully interactive 3D model, encompassing an area of 1,600 km2 which represented prominent locations such as the Needles on the Isle of Wight, bournemouth pier and Durlston Lighthouse as well as the proposed turbine layouts.
The resulting 3D model of the wind farm was one of the most extensive and detailed ever produced and provides accurate views of the proposed wind farm from any location within the 3D

POSITIVE FEEDBACK Feedback on the 3D model was overwhelmingly positive. Irrespective of whether or not individuals agreed with the Navitus bay development, the model clearly presented the proposals in a non- technical and unambiguous way which facilitated open, informed and constructive discussions about the scheme.
