There’s a college in Chicago, i think it’s IIT maybe, that used aerial photography to map out the student cow paths, then they redid all the sidewalks to incorporate those paths.
Edit: they ended up adding a building in a grassy area and maintained all the hall/walkways of the building in line with the sidewalks/cowpaths. Kinda neat.
Good distinction. I imagine anyone typing into a google search bar with an android device nearby could have their keyboard mapped though, if Google ever wanted to do such a thing.
