Visualizations are our bread and butter since our foundation in the year Do you need a visualization for your project? Fast and accurate? Then let us know! We can visualize your project for you, in an extremely time- and cost-effective way. If we visualize the project for you, you can still try out different variables yourself, such as day, night, shadow impact and wind direction.

Unlike with noise or shadow flicker, there are no formulas to determine the impact or set limits. Instead, the study addresses the potential viewers that could be affected demonstrating if they would be affected, and if so what it would mean. Viewers may include commuters who see the wind park from a road, local residents, but also tourists that may be concerned with their treasured views. In addition, the VIA is assessing how the wind park develoment blends into the overall landscape.
Methodology Visual impact studies may provide. To demonstrate the various parts, we have conjured up a ficticious power plant development with 2 rows of 6 wind turbines.
One row consists of 3MW turbines, the other of 1MW turbines with smaller rotors. Hub heights are roughly the same. As can seen on the map, the 3MW turbines are spaced m from each other. The others only m. In a photo montage a picture is taken from a certain view point, which could be a house or a road or any other visually sensitive point.
We can then show the status quo as well as the photo with the turbines superimposed. Here, the turbines from both rows are clearly visible. Due to the distance of the smaller turbines from the view point, that row adds an entirely separate visual impact.
In a "Zones of Visual Influence" - map, we can show how many turbines would be visible from which point. In this instance, up to 12 turbines could be theoretically visible. Multiple point line of sight looking outwards from any number of points with a common feature code, optionally within a specified surface coded area or all such coded points anywhere in the survey.
This method allows the user to define a grid of 'target' points at a specified grid interval and height above the ground. ZVI Analysis. The user has full control over the colour banding to define the number of points visible from each grid eye location. What can also be produced is a survey containing text boxes whose colour is defined by the number of points visible from the grid point beneath the box and the number contained is the exact counter value.
The target counter option above has determined that there is line of sight from some receptors to some or all of the target points, but it may be necessary to assess which targets are visible. The user may select any location within the DTM and LSS will draw lines radiating out towards every visible target point. What is more, because LSS works on a triangular mesh at all times, the user is free to select any point within the DTM and LSS will interpolate the elevation from the triangular mesh.
The user has control over eye and target heights above the DTM and the calculation will take into account any heighted linear or surface obstructions in the way. This is calculated from a user-defined grid of receptors and can measure either the largest contiguous feature visible, the total of all contiguous features or the maximum spread from the furthest left to the furthest right extent of the development.
The information is stored as a horizontal angle in degrees. Both this command and 'Visibility Surface' are the only true tests of likely impact because the results reflect the effect that distance has on the apparent size of the object a large object up-close has more visual impact than the same sized object further away [all things being equal]. In the above example, we have four distinct objects, A, B, C and D.
Any of these results can be produced for a user-defined grid of receptors and for a user-defined angular interval. What is produced is a model where the elevation of every grid point represents the chosen Horizontal ZTV in degrees. It is then possible to contour this or display coloured bands in order to highlight potentially problematic areas of high 'impact'.
And remember, in LSS if you add your own heighted links or surfaces into the model, these will act as barriers to the ZTV, thus allowing you to calculate a more realistic picture of the likely impact. And, furthermore, if you are using vector mapping information such as MasterMap in the UK LSS is capable of applying surfaces to different features, thus giving you a really quick way to apply heights to objects such as buildings and woodland. Here we define a grid of eye points as above, but we are interested in the degree to which the target s fill the viewers vertical field of view as defined by points within specified surface coded areas.
