Bar Crawl

Two things I like – beer and maps.  Maps about booze are even better.

Having grown up in the Midwest – born and raised in Minnesota, with lots of family in Wisconsin, as well as living in Madison and Ann Arbor, it’s no surprise to me that people there like to drink.  It’s a part of the culture.  Now, we have some maps to prove it.

The blog floating sheep has some great maps of America’s beer belt.  First, the total number of bars in various locations across the US, based on Google maps’ directory.

Next, a point of reference – a map showing the relative popularity of bars to grocery stores – red indicates more bars than grocery stores:

Finally, putting Wisconsin’s culture on display, a map of how many Google Maps entries there are for bars, normalizing the data to show the relative popularity of them.

Unsurprisingly, we see all sorts of concentrations of bars that correlate with population density – namely, cities.  Wisconsin, however, is punching well above its weight.   That well-worn drinking culture shines through.  Southern cities, conversely, seem a little thing based on their populations – perhaps a holdover from dry counties and other temperance movements?

Either way, it’s a cool set of maps.

Historic DC Maps

In the same vein as UCLA’s Hypercities maps I’ve discussed previously, I recently ran across some more historical maps from Shannon over at We Love DC.  The maps themselves are ok, not nearly as detailed or interesting as the Hypercities maps, taking the historic maps and re-projecting them onto an interactive Google maps interface.

More interesting to me, however, is an older post of Shannon’s that directs you to David Rumsey’s historical map archive, as well as a world-wide index – which includes (unlike the Hypercities site) two DC maps – from 1851 and 1861.

The index page shows you the wide variety of locations covered:

The interface is similar to the hypercities one, allowing you to toggle on a historical map that has been manipulated to match the projection of the underlying Google interface.  This allows you to navigate around the environment.

First, the base layer, a current aerial of DC:

Here’s the 1851 map of DC:

DC_Hist_5

And the 1861 map:

DC_Hist_2

You can adjust the opacity to directly compare the current conditions to the map – some interesting details concern the shoreline of the Anacostia, the existence of Hains Point, as well as the evolution of the city’s built environment:

DC_Hist_3

The detail in the 1861 map is fantastic.  Extremely detailed, right down to the figure ground of individual buildings – as well as demonstrating how much of L’Enfant’s plan had been built out on the eve of the Civil War.

DC_Hist_4

On the edges of the L’Enfant city, the map shows how historic roads have shaped the current city, such as Columbia Road meeting Connecticut:

DC_Hist_7

Also, the property boundaries outside of the L’Enfant plan influenced the street patterns of later developments.  Note how the slightly off-kilter grid of LeDroit Park corresponds to the landholdings of one C. Miller:

Very cool stuff.

Fun with maps

Something you can do to waste time during the snow day – UCLA has a great website with a series of historical maps scaled and overlaid on a contemporary aerial image for select cities around the world.  The closest to DC is New York, but this is still a lot of fun to play around with.

Hat tip to Dale for the link.

Some screenshots to give you an example of the interface and how it works:

There are tons of historical maps and an incredible amount of detail to explore here.  I’ve been playing around with it and feel like I’ve only scratched the surface.  Very cool stuff.

Fun with maps and movies

DCist takes note of Matt Yglesias’ tweet on the New York Times’ fantastic interactive map of various metropolitan areas, broken down by zip codes and how popular each of Netflix’s top 50 rentals of 2009 was in those areas.

The geographic patterns are fascinating, and quite revealing about the social and economic geography of the DC area.

Tyler Perry is popular in PG County, but not so much at Andrews AFB. Also note the other cities on the right.

Milk presents an almost complete opposite map of popularity.

Role Models. Complete with spikes in popularity at couple military bases (Andrews AFB, Fort Meyer, and Fort Meade) and two colleges (Georgetown and Maryland).

Absolutely great stuff.  Maps are available for 12 Metropolitan areas: New York, Boston, Chicago, DC, the Bay Area, LA, Seattle, the Twin Cities, Denver, ATL, Dallas and Miami.
