The Engineer decided a view that would show the Saint Francis turbine at variable distances would be helpful in describing view impacts to residents. POITRA used a view from two miles north of the town on BIA Hwy 1. The wind farm lies just southeast of Saint Francis. Little modification was necessary on the Engineer provided base photograph.
POITRA modelers created a turbine model that matched the supplier's tower and rotor size specifications of those selected for the proposed site. Turbine models were placed at in one mile increments starting at one mile from the camera and ending at ten miles. The distance site model was camera matched, lighted, rendered and composited with the base photograph to complete an accurate photo-realistic distance reference simulation.
Radio antennas, a grain elevator and a water tower with known heights and near the town were used to confirm camera orientation and check perspective.
POITRA graphic artists labled the turbines in the simulation for use at public meetings.
The finished simulation was used in meetings between the Bureau of Indian Affairs (BIA), Sioux Tribal Government and local residents.
