Posts about Maps
These maps show nearly every retail storefront in central DC compared to those in New York, Detroit, and other cities. Since retail streets are usually the most lively streets in a city, the maps offer a nice proxy illustration of urban vitality.
In general, the more red dots you see in a small area, the more lively that part of town will be. More stores, after all, mean more destinations for people to visit.
Here's the DC map in greater detail:
You can easily see retail streets like U Street and H Street, and bigger clusters like Georgetown and Dupont Circle. On the other hand, primarily residential neighborhoods are mostly blank.
Unfortunately the data clearly isn't perfect: The retail complex in Columbia Heights seems to be missing, as are the giant gift shops in the Smithsonian museums, and some neighborhood corner stores.
Still, the maps are an instructive illustration of urban vitality in general. You can see patterns here, and those patterns are real.
Zooming out to the regional scale, downtown areas outside the District like Bethesda, Silver Spring, and Alexandria become prominent.

Compared to other US cities, DC looks decently lively. The country's dense, transit-oriented cities like San Franicsco and Boston fare well (New York is a crazy outlier), while economically disadvantaged cities like Detroit and sparser more suburban-style ones like Raleigh show fewer stores, indicating less urban liveliness.
Of course, retail storefronts are a simplistic way to look at this. New York's streets have a lot of stores because New York is tremendously dense, so there are lots of customers to support them. On the other hand Tysons Corner has a lot of stores because it's a big suburban mall that people drive to from miles around.
Even suburban malls offer a sort of liveliness, however. So while these maps may say little about walkability, they are a good proxy for liveliness.
Did you know our region had bike lanes all the way back in 1896? This map shows the best way to get around DC and parts of Maryland and Virginia on two wheels before the start of the 20th Century.
The map is one of 70 that the DC Public Library recently added to its Dig DC collection.
These newly available maps are part of DCPL's ongoing effort to digitize the Washingtonia Map Collection, which includes material from various sources dating back to 1612. So far, the collection on Dig DC includes maps from 1768 through 1900.
According to the note above, the direction and frequency of triangles along paths indicates the slope and incline of hills. If topography is your top concern, this map could still be helpful in choosing your best route: The gentle decline of Bladensburg Road as you travel southward into the city could certainly offset traffic considerations.
It's also interesting to note that certain roads— What else about this map do you notice?

Some of this new impervious surface reflects already urban places getting denser. That's a good thing; by adding a little impervious surface in Arlington or along Connecticut Avenue, for example, the region saves a greater amount from being built outside the Beltway.
But much of this new surface isn't responsible development. The NASA post points this out, saying,
In addition to the widening of the Beltway, notice how pavement has proliferated in Fairfax and Loudoun counties in Virginia and Prince George's and Montgomery counties in Maryland. The District of Columbia was already densely developed in 1984, so the changes there are less noticeable.
The map also doesn't even zoom far enough out to show places like Frederick, Howard, Prince William, Fauquier, and Stafford counties, where the change is even more dramatic, and where even less of the new pavement is in places that are walkable or oriented to transit.
This is an effect of "height-itis"
Week after week, local boards in many jurisdictions make decisions, like taking housing away from the Georgetown Day School project in Tenleytown, which remove a little potential housing in the core. Those choices don't keep even one square foot of land unpaved (and even if they did, it wouldn't be worth the tradeoff), but they do push a little more growth out to where it affects maps like this.
Our region can protect natural resources, but not until people are willing to make them a priority. Until then, this trend will continue.
Had an 1861 proposal come to fruition, much of Virginia would have become Maryland, much of Maryland would have become Delaware, and West Virginia would have simply remained Virginia. Here's what their demographics would look like today if all that had happened, and a look at what that might have meant for the 2012 presidential election.
First, a look at these states' boundaries today:
This includes the population totals and some demographic information from the 2010 Census, as well as the electoral votes allocated based on that census.
What's below shows the "new" states, along with the current state boundaries.
With a population of over 11 million, New Maryland would be the 8th most populous state in the 2010 Census. Despite having a couple of hundred thousand less people than #7 Ohio, it would have the same 18 electoral votes as the Buckeye State. New Delaware's extra population would add an electoral vote to what Delaware has, and New Virginia would have two more electoral votes than West Virginia.
Even if the 23rd Amendment didn't limit DC (and presumably New DC!) to no more electors than the least population state, the almost-million residents in New DC would not be enough to get it an additional elector.
When it comes to race, Delaware and New Delaware (as well as West Virginia and New Virginia) have very similar compositions, and New Maryland's numbers are similar to Maryland. Clearly, Virginia's eastern population is racially similar to Maryland. With the addition of Arlington and Alexandria, New DC's racial population percentages are almost exactly swapped. (Although not shown here, New DC's Hispanic population would be double that of DC.)
Here's how I made the new map
I used current county/city jurisdictional boundaries when creating the new states. While these boundaries may be different from those in 1861, the general analysis presented here would be relatively unaffected. (The most noticeable boundary difference would be modern Alexandria, which has expanded beyond the original DC "diamond.")
The post that inspired mine states that the Blue Ridge Mountains would be the boundary between New Virginia and New Maryland. I georeferenced the 1861 map onto a current and geographically accurate map to determine which current jurisdictions would fall into each state.
Alexandria and Arlington would return (or "be retro-retroceded"??) to New DC. New Delaware would inherit all of the Delmarva Peninsula. And, the three counties in the panhandle of Maryland would move to New Virginia.
I re-calculated the electoral votes for each "new" state based on the populations shown in the second image (and assuming there are only 49 states since West Virginia is no more). Overall, the proposed multi-state area would lose two electoral votes, as there is one fewer state in the calculation.
2012 election would have been different, but not that different
I also decided to take a look at how the reconfiguration of the region may have impacted a recent election. The image below shows the 2012 election results (by county/city), along with the aggregated totals (and electoral votes) of the new states.
In the actual election, Obama took 29 electoral votes in the region and Romney took West Virginia's five votes. Under the new configuration, Obama would have received 25 electoral votes while Romney would have garnered New Virginia's 7 votes.
This very brief analysis doesn't show any earth-shattering differences between the current state configuration and the proposed one. It doesn't touch on economic issues like Gross State Product, employment, personal net worth, salaries, etc. Redrawing state boundaries would not have changed the result of the 2012 election, but can you think of an election where it might have made a difference?
Another point of interest: An overwhelming majority of Metro stations would be in New DC, so would New DC even bother trying to participate a multi-jurisdictional hydrid commuter-subway system like Metro, or would it have just decided to create a District-only system and had New Maryland feed commuters into the Metro via a New Maryland MARC?
What else do you think could be different, for better or worse, if these were our state borders?
In the 1940s, there was a proposal to make East Capitol Street into a wide, monumental avenue. This map shows what it would look like, and provides some other glimpses into what DC was like at the time.
I spotted the map in a recent Washington Post story about cartographer Pat Easton painting it on his dining room wall via a projector. I took one glance and saw how different the DC it depicts is from how DC looks today.
Today, East Capitol Street is a typical Capitol Hill street: It isn't very wide, and most of the buildings along the street are small. The map shows an East Capitol that looks like the National Mall continuing east past the Capitol building and stretching to the Anacostia River.
It turns out the map was drawn up by the National Capital Park and Planning Commission (NCPC) in 1941. It details proposals that would have incorporated much of the land between Constitution Avenue NE and Independence Avenue SE into new space for federal and District government buildings. The Library of Congress has a copy of the map on their website, where you can zoom in and see many of the details.
One of the most notable things is how many of the (now historic) buildings along East Capitol Street today would have been razed to make room for wider streets and office buildings. The corners of Lincoln Park in Capitol Hill would have been rounded off to make the space shaped more like an oval, and Independence and Constitution Avenues would have been widened to include some freeway-like sections along with tunnels underneath the Capitol Building itself. That would have meant that the roads stayed very wide for their entire length across the city.
Had all of this this happened, East Capitol would probably look similar to today's Independence Avenue SW near the USDA Complex.

The map has lots of signs of the times
Other details I notice are that there is a stadium near where RFK stadium sits today, along with other athletic facilities, including tennis courts and an indoor swimming pool.
There's also no bridge across the Anacostia River. Instead, Consitution and Independence Avenues both veer off the map, traveling along the Anacostia's western shore. That's obviously different from today, as we now have the Whitney Young Memorial Bridge.
It also looks like there where plans for a new railroad bridge and tunnel that would cross the Anacostia closer to today's RFK site and, presumably, link up with the current right of way near L'Enfant Plaza.
And of course, since this map was drawn in 1941, there are no interstate highways cutting through the southwest and southeast quadrants of the city, and Constitution Avenue dead ends at the Potomac rather than leading to today's Roosevelt Bridge.
What do you notice in the map? What do you think of some of these ideas? Let us know in the comments.
This amazing map from 1861 shows a federal government proposal to redraw the borders of Maryland, Virginia, Delaware, and DC. The reason: To spite Virginia for the Civil War and better-protect the capital from attack.

This arrangement would reduce the size of the State of Virginia at least one-half, leaving the name of Virginia to that part only which is now mainly loyal.Alexandria and Arlington would have returned to DC, which would have remained independent of any state.
The disloyal section, comprising all the great cities of Virginia—
Richmond, Norfolk, Fredericksburg, Lynchburg, etc.— and all the sea-coast, would be annexed to Maryland, while Delaware would rise, by spreading over the whole peninsula between the Chesapeake and the ocean, to be a State of considerable magnitude.
Under this reconstruction Maryland would become one of the three great States of the Union. We need hardly direct attention to the clause in the Secretary's report which hints that emancipation in Maryland must be the price paid for this acquisition of territory.
When Cameron came up with his idea, the Civil War was less than a year old. The western more rural portions of Virginia had hoped to remain in the Union, while the more urban eastern portions had voted overwhelmingly to secede. In theory, this proposal therefore would have accomplished several goals. It would have:
1. Separated off the loyalist western parts of Virginia, allowing them to be reintroduced to the Union as a northern state.
2. Punished eastern Virginia, the intellectual and economic heart of the Confederacy, by taking away its independence as a state.
3. Rewarded Maryland and Delaware for remaining in the Union.
4. Protected Washington from having a hostile territory directly across the Potomac.
It's not as crazy as it seems
In 1861, as Cameron was making this proposal, West Virginia was already in the process of splitting off from Virginia to become its own state. How exactly to draw its borders and what to call it was a perfectly reasonable question.
The most doubtful part of this idea is the notion that new-and-bigger Maryland would be a safe northern state. Although Maryland never seceded, it was a slave state and its loyalty to the Union during the Civil War was tenuous at best.
Adding the wealthy and populous parts of Virginia to Maryland seems more likely to have drawn Maryland towards the south than vice versa. Presumably that's why the deal would have required Maryland to free its slaves.
Of course as we all know, this proposal didn't work out. West Virginia's boundaries and name became official in 1863 when it was admitted to the Union as its own state, and Virginia was itself readmitted in 1870 following four brutal years of Civil War.
But it's interesting to look back and see what could have happened, had history turned out just a little bit differently.

In 1921, you could take the train from downtown DC to Annapolis, from Baltimore to Harrisburg, or Winchester to DC. I built a subway-style map of the rail service our region once had.
In the Mid-Atlantic region, hundreds of trains and ferries used to serve passengers at over 1,370 stations. But they were run by dozens of individual companies, meaning there was no single unified system map to let people know how to get from A to B. Passengers had to pour over dozens of often-opaque timetables to know how to get around.
Doing that was no simple task, as I can now attest to after having trawled hundreds of these tables in The Official Guide of the Railways to pull together this one map.
Subway-style maps were a genius invention of the early 20th Century. By combining old railway maps with service schedules, they allow travelers to understand at a glance how the transit system works without relying on byzantine schedules.
This map says a lot about how the region worked back then
My Mid-Atlantic map shows about 29,000 square miles, centered on DC and Baltimore. I tried to map to the logical endpoints of the railroads, where they converge before diverging again.
Baltimore's prominence as a major transportation hub is clear, especially for waterborne travel. Ferries hit remote villages and towns along rivers up and down the Chesapeake, delivering people and goods between the villages or back to the dozens of railroads serving Baltimore. Though it's tough to imagine the Rappahannock or Piankatank as transport corridors today, steamer service was often a lifeline to the rest of the country.
And while the city itself is absent from this map, you can see Philadelphia's strong influence in the northeastern corner. The Baltimore & Ohio's Main Line to Washington, the Pennsylvania Railroad's Main Line along the top of the map, and Pennsy's Washington lines all point to that formidable hub.
Clear, too, is the shape of our contemporary rail infrastructure in the old system. MARC and VRE both make use of old passenger routes, while Metro and Baltimore's light rail both make use of abandoned rights-of-way.
From this GGWash post, this map shows the MARC, VRE, Metro and Baltimore light rail.
There are also some particularly evocative and historical station names. One wonders about Tuxedo, just outside DC, or Screamerville on the PF&P. Buck Run and Doe Run are adjacent stops on Pennsy's Pomeroy Branch. Baltimore's Penn Station was once optimistically named Union Station, though since city's eight stations made it hard to centralize everything, the name never took off.
This is hardly a complete transit map, of course. Because it is almost impossible to find contemporaneous timetables for every company, I had to limit myself to the companies and stations appearing in The Official Guide. Hence, the jarring absence of Silver Spring from the B&O and the lack of the streetcar line from DC to Glen Echo.
What kind of system could we have today?
Beyond just being fun for train buffs, I hope this kind of map will inspire transit advocates to think big about what we might have again one day.
Some months ago, a caller to the Kojo Nnamdi Show was hopeful that Winchester might someday get commuter rail service. It actually turns out the B&O ran through Winchester as well as a number of small West Virginia towns before hitting the main line to Union Station. Maybe that would be a good place to expand MARC's Brunswick Line.
Or perhaps, if Baltimore again becomes the kind of major metropolitan center it once was, it would make sense to reactivate the Old Main Line between Baltimore and Frederick. Or, maybe it wouldn't! The point is to think big, to see where nostalgia and practicality might align.
That in mind, what line do you wish would see a revival? Also, I'm still open to suggested revisions for this map before releasing it as a poster that's for sale. Feel free to nitpick in the comments below!
Is it frustrating to try to travel from Columbia Heights to Brookland on foot, bike, bus, or car? The District Department of Transportation is studying ways to make it easier to travel east-west in this area, and a new interactive map lets you point out problems.
This WikiMap is part of DDOT's Crosstown Multimodal Transportation Study, the goal of which is to improve all modes of travel between 16th Street NW and South Dakota Avenue NE. It lets users identify problems with and suggest solutions for
walking, riding a bike, driving, transit, public space, parking, and intersections, and is a user-friendly way to participate in DDOT's search for long-term solutions.
People who frequently commute by foot, bike, bus, car, or other means through the corridor have firsthand knowledge on the area's congestion, safety, and streetscape issues. They're also likely to have ideas on how these issues can be addressed to improve transportation mobility and mitigate impacts on the surrounding neighborhoods.
Beyond the crowdsourced map, DDOT recently kicked off the first in a series of public meetings for the project aimed at gathering feedback.
The interactive map will be available on DDOT's website (just click the first image in this post) for several months.

Ever wonder what transit projects are in under construction, planned, or proposed in Denver or Honolulu? Check out a captivating new Transit Explorer that maps transit development in more than 40 cities in North America.
Developed by Chicago-based urbanists and transit professionals Yonah Freemark and Steven Vance, the new transit project visualisation is an extension of the popular transit openings and construction starts post that Freemark has published on his blog The Transport Politic annually since 2009.
"We wanted to provide people an open-source, easy to use, and good-looking interface by which to explore transit in North America," says Freemark. "Transit Explorer is all about helping people understand where fixed-guideway transit is now and where it could go so that they can imagine how to improve transportation systems in their own cities and compare plans across the continent."
Transit Explorer shows the wide variety of transit projects in some stage of development in the Washington DC region, including the Silver Line phase two in Virginia, H Street streetcar line in DC and the Purple Line light rail project in Maryland.
