It feels like whether or not it's possible to make a model of new york misses the point. This kind of project could just as easily scale up to be an isometric map of the entire world, every city, every forest, every mountain hut, and update continuously as new buildings are built and cities grow. Expensive yes, for now- but the speed and scale to make and maintain such representations will absolutely be outside the realm of what was previously possible. Not just maps of the world, maps of human knowledge, history, to such detail that would entail not just tens of thousands of hours but billions or trillions of hours if done by hand.
