How Spatial Data Analysis Can Make Smart Lighting Smarter

The paper proposes the use of spatial data analysis procedures to automatically determine lighting situations to allow for easy estimation of the predicted power efficiency of lighting retrofit projects. The presented method has been applied to real-world data for a large city, covering over 50,000 lamps. Results show that the accuracy of the algorithm is promising but, more importantly, demonstrate that the traditional estimation methods, based on the existing infrastructure parameters, can lead to highly biased results compared to the proposed method.
