Legion Way Turbine Photosimulation
Below are photosimulations of the wind turbine at the primary legion way site. Single click on a red marker to see a thumbnail photosimulation of the turbine from that point on the map. Double click to see a larger picture. The location of the turbine is marked by the blue icon. Larger pictures: A, B, C, D, E, F.
How the photosimulations were created
The turbine location and size in the photosimulations were calculated in two ways: using geometry, and by floating balloons at the hub height and the blade tip height. These two methods were used together in order to assure accuracy. We assume the length of an object in a picture (such as the tower or a blade) is proportional to the angle of view cut out by the object. This is a good approximation for small angles. In order to calculate the constant of proportionality, we use a real object in the picture with known height and at a known distance to the camera.Below we include a blackboard explanation of how calculating the size of the blade in the picture for photosimulation D. The distance from the camera to the turbine is calculated using Google maps. In this case, the blade size in the picture is estimated to be about half the height of the child in picture.
1000 foot radius around proposed site
The setback from the Legion Way site to the nearest occupied building is 1000 feet. Below is a picture of a circle with that radius centered at the site. The map was produced from the official town map database.
