@JensWiesehahn Hi Jens, I believe my approach is similar to "time_in_daylight", which I don't really know enough about. Anyway, my code is mostly Python except the most computationally intensive part of calculating the shadows on each pixel of the DSM for about 250-300 position of the sun in the sky. Ultimately, the "darkness" of a pixel should be proportional to the time spent in the shade when sunlight is present.
