The Manhattan Grid extended to every point on Earth

This will greatly simplify trips between NY and my home in MN: "Driver, drop me off at the corner of 6,593 Ave and S 2,265 St."

I showed this yesterday at the NYC meetup Hack&#38;Tell and it seems to have blown up since then! Thanks for the post.<p>My favorite part is that the avenues converge at "Manhattan's North Pole" aka Kazakhstan.

Very cool of course.<p>Why do the avenue lines meet at an antipode? In Manhattan, they are parallel, they don't converge.<p>I understand the difference between latitude and longitude lines. A meridian of longitude is a great circle centered at the Earth's center; a line of latitude is a small circle (the analogue of a chord in a 2D circle on a plane) whose center lies north or south of the Earth's center in three dimensions. Longitude lines divide a sphere like slices of an orange, converging at poles; latitude lines divide a sphere like a tomato slicer and do not converge.<p>There's actually two "poles"; aside from the one in Uzbekistan that everyone is seeing, there's another in the South Pacific Ocean at the antipodal point from Uzbekistan. So the avenues are being treated as meridian lines; great circles. Would it be more accurate to extrapolate avenues as parallel small circles?<p>We could test this theory by inspecting whether Manhattan's actual grid respects the curvature of the Earth. If the avenues are closer together at the northern end of the island, then the avenues actually do behave as meridians. If not, then the extrapolated avenue lines should be small circles and would not converge. You'd still have a pole in Uzbekistan, where the last street becomes an arbitrarily small circle, but just one avenue line through it. (I gotta run at the moment but will throw some trigonometry at this later.)

The whole world? Like it extends out to Brooklyn and up to the Bronx?

These things are always only <i>sorta</i> tongue-in-cheek.<p><a href="http://strangemaps.files.wordpress.com/2007/02/steinberg-newyorker.jpg" rel="nofollow">http://strangemaps.files.wordpress.com/2007/02/steinberg-new...</a>

The naming is a little off, isn't it? South of Houston all bets for street numbers are off, so I'm fine with making up South Xth street, but you should maintain the consistency the grid currently has.<p>You've lost the East/West distinction between the streets, so the West streets are just Xth Street, instead of West Xth Street like they should be. Worse, the avenues East of 1st should be named alphabetically, not as E Xth Ave. For consistency, I'd increment them as Ave A, Ave B, Ave C ... Ave Y, Ave Z, Ave AA, ... You've turned Alphabet City into just the East Avenues. Sacrilege.

All roads lead to Uzbekistan.<p>I think this would be a great way to see differences in map projections.

I finally have a NYC address and I'm still paying only Toronto suburbs prices!

Reminds me of this map that made the cover of the New Yorker a long time ago: <a href="http://strangemaps.files.wordpress.com/2007/02/newyorker2.JPG" rel="nofollow">http://strangemaps.files.wordpress.com/2007/02/newyorker2.JP...</a>

A shame this came out too late to be added to XKCD's "Map Projections" comic. I'd call it the "Manhattan Uzbekistan Projection."

This doesn't make a lot of sense for Manhattan, because the grid doesn't have a center point; there's no numbering convention for streets south of Houston or avenues east of York/A. It would make more sense for cities like Miami or Salt Lake City, where there is a quadrant system and (for the most part) consistent spacing of streets

I don't think the grid is completely correct in Manhattan, even where the grid exists. It puts Washington Square Park , which southern end should be 4th street, as 6th street, and on the northern end of the grid, George Washington Bridge, which comes into Manhattan at 175th (I believe), is marked at 180/181st.<p>This is a really cool map, but some minor adjustments and testing to get the correct fit in Manhattan first would make a notable improvement in the overall product. I'd say fitting goals would be Houston as 1st street, and maybe 191st-200s area for north bound (Bronx continues the pattern, but it's much less consistent). Good work!

Man, and to think my friend's 5th floor walk-up in a little building on 1st and 1st would truly be the center of the universe.

One of my cross-streets is 13337th Ave. That's like an order of magnitude better than being just on 1337th Ave., right?

Wow, it lines up almost perfectly with Montreal's rather askew grid, what a coincidence.

This just goes to show that 1st and 1st really <i>is</i> the center of the universe

The Chicago grid actually <i>does</i> extend well into Indiana, and its numbering system makes slightly more sense. It'd be nice to have a version of this for the Second City.

Oh, why did you do it? Real estate developers in Bangalore have already started quoting higher prices by labeling the NY address to local properties :(

What is this?

Maybe this will help Herman Cain.

I love the Uzbekistan conspiracy.

Salt Lake City/valley has a better grid system, just saying. I dearly miss it.

Okay, cute, but the "Manhattan Grid" barely extends to lower Manhattan.

I live at the corner of 64,779 St and 12,785 Ave.
