Human: I've been browsing Google Maps and it's impressive how detailed their satellite imagery is. How have they put together a fully interactive 3D mapping of the world?

Assistant: Google started out by using satellite images to create maps of the entire world. Then they added additional data sources such as land-use data, aerial photography, and crowd-sourced information to make their maps even more accurate. Finally, Google Maps used advanced computer algorithms to create a 3D model of the Earth's surface. They did this by taking all the information they already had and using it to estimate the height of every location on the planet. The result is a world map that looks very similar to what we see with our own eyes.

Assistant: There are many pieces to it, and you’ll probably find a lot of technical resources that explain how they did it. There’s also a lot of other mapping services like Google and OpenStreetMap.com that use their own technology. But I think the key to why this works is that they’re not actually photographing every single part of the world, they’re stitching together photographs from multiple sources into a seamless 3D model.
