The numbers are the number of each arrondissement

The blue stripped zone are those where haussman architecture exists at WWII time

The red stripped zone are those where "suburbs" architecture may have been at WWII time (for the one in 3rd arrondissement it is an area called "the Marais", a very old part of Paris absolutely not modified by Haussmann)

the white lines are the biggest city roads of paris called grand boulevards, they should also form multiple branchs of a star starting from "place de l'
