Monitoring of biodiversity impact is an important part of windfarm regulations. Spoor offers a solution for long-range detection, continuous monitoring and collision detection of birds near windfarms. It helps windfarm developers and operators to gain insights and guide mitigation measures. The system can track multiple birds and flocks up to 3 kilometers. The software estimates the bird flight paths and visualizes flight patterns before and after construction. The system can even be trained to recognize different bird species.
