No, Manhattan as it relates to 90 degree features is the only one of its kind - a geometric property that is named after the geographical layout of a city.

This definition comes from Manhattan distance, which also has other names like taxicab distance, since it describes the actual distance it takes to travel between two points in a city like Manhattan by taxi.

The analogous metric that includes diagonals is known as Chebyshev distance, named after a mathematician. Also known as chessboard distance, as it describes the distance it takes a king to move to a position.

The only other geographically-named metric is Canberra distance, which has nothing to do with diagonals nor the geographical layout of Canberra. Its name comes from its inventors, who lived there.
