Why would you want to do *that*??? Are you measuring the angles of intersection of some lines traversing these N-S running streets or something? As a topologist by training, I really cannot see any good reason why you should *care* about angles and such like, if all you are concerned with is following maps to reach particular points. Do you actually look at (and use) the scales printed on your maps? Do you find the (geometrically wildly wrong, but topologically accurate) subway maps in NYC hard to use? or what? -- Michael L.
