I came across a really great article that compares changes in Google Maps and Apple Maps over a year. It’s really great to see how much Google is experimenting and improving their product.
Similar to how a software engineer refactors their code before expanding it, Google has repeatedly refactored the styling of its map as it has added new datasets. And we see this in the evolution of Google Maps’s cartography:
As Google has added more and more datasets, it has continually rebalanced the colors, weights, and intensities of the items already on its map – each time increasing its map’s capacity for more.
