I mapped quite a bit of Morocco while traveling through there recently. Interestingly, I find that a lot of sports fields in villages are for both football and basketball, but the basketball structures aren't visible from aerial imagery. Rather you will know they are there only if you actually see the pitch with your own eyes. So, while automatically identifying leisure=pitch might be possible with neural networks, the tagging still needs a human being to visit the site in order to be complete.
