Traditional neighborhoods vs. urban prairies: block by block in Detroit

Posted on by

National Geographic has quite a map showing Detroit with each block coded to be more or less less a traditional neighborhood or an urban prairie/naturescape. Here is the map:

DetroitBlockbyBlockNeighborhoodorPrairie2015NatlGeo

The map clearly shows clusters of both kinds of places, which contradicts the idea (reinforced by numerous stories and images) of recent years of a monolithic empty Detroit. As the text at the bottom left notes, “Many neighborhoods along Detroit’s perimeter are as densely populated as the city’s wealthier suburbs.” So it isn’t that all of Detroit needs fixing; neighborhoods that suffered from similar issues including deindustrialization, the loss of white residents, the lack of capital both for businesses and residents/homeowners, and crime do need the attention.

Patterns in “All Transit – Guess the City”

Posted on by

A new online quiz moves you through four levels of difficulty as you try to identify the American city by only the traces of mass transit routes. Four quick patterns I observed playing through the levels:

1. The easier ones to identify are usually (1) big cities with (2) identifiable bodies of water.

2. One thing I found helpful on the map was the difference shown between bus and train lines. If there were fewer train lines with more bus routes along straight roads, I guessed Sunbelt cities. With their more recent histories based on automobile travel, they would be more likely to implement buses on the existing roads. But, some of the cities with more bus than train lines ended up being mid-sized cities in the Midwest and Northeast that probably couldn’t financially support large train lines.

3. There are a lot of mid-sized American cities and unlike #1 above, they are (1) not as well-known and (2) often away from large bodies of water.

4. Level 4 was pretty insane. For example, could you easily spot the difference between Davie, FL, Bryan, TX, Richardson, TX, and Poway, CA via their bus stops?

Mapping every road in the United States

Posted on by

The United States has a lot of roads and you can see them all on these state and national maps:

Roads, it turns out, are fantastic indicators of geographies, as evidenced by Fathom’s All Streets series of posters. A few years ago the Boston design studio released All Streets, a detailed look at all the streets in the United States. The team has since produced a set of All Streets for individual states and countries.

Using data from the U.S. Census Bureau’s TIGER/Line data files (Open Maps for other countries), the designers are able to paint a clear picture of where our infrastructure bumps into nature-made dead ends. In states like North Dakota and Iowa you see flat expanses of grids. Nebraska has a dense set of roads in the east near its more populated cities that dissipates as you head west towards the rural Sandhills prairie. A dark spot near the southern tip of Nevada punctuates the otherwise desert-heavy state, conversely, the Adirondack mountain range provides an expanse of white in a dark stretch of New York roads.

I do find the smaller maps or smaller scale views more interesting because they do show some differences. Looking at the national level doesn’t reveal all that much because we are now used to such images based on infrastructure and big data, whether based on cell phone coverage or interstates or lights seen from space or population distributions.

I could see hanging one of these – perhaps the Illinois version?

“War Over Hollywood Sign Pits Wealthy Residents Against Urinating Tourists”

Posted on by

GPS hasn’t just altered the lives of LA residents living on formerly quiet streets near the freeways – now, neighbors of the famous Hollywood sign have convinced Google and Garmin to remove their street off their maps due to an influx of visitors.

Everyone involved agrees that the situation has become a powder keg. “Neighbors have been yelling,” says Tamer Riad of Rockin’ Hollywood Tours. Homeowner Heather Hamza, whose husband, Karim, runs a diving company servicing film productions, claims she’s experienced “aggressive” tourists “cursing and spitting at me.” She adds that, after the recent holiday period, “There is rising, palpable tension between the residents and visitors. Everybody is infuriated. I shudder to think if any of these people coming up here have weapons in their cars. One of these days someone will get shot — it is that bad.“…

A sign originally erected to advertise a neighborhood to the world has become that neighborhood’s deepest frustration, and affluent residents have been fighting back. Although several thousand houses lie in Beachwood Canyon and neighborhoods adjoining the nearby Lake Hollywood Reservoir, most of the clamor comes from a few dozen activists in the area. They have lassoed various government and commercial entities into doing their bidding. They’ve persuaded Google, Garmin and other tech giants to literally take their exclusive neighborhood, where the average home costs $1.5 million, off the map for people searching for the sign. They’ve pushed City Hall to enact strict new parking regulations and to go after tour-bus operators. They’re fighting for the closure of a trailhead gate to Griffith Park and the removal of one popular viewing spot. And they’re not done.

Some residents say that a key element in winning the hearts and minds of city officials is a 30-minute advocacy film that, according to its producer, former actress and onetime Hollywoodland Homeowners Association president Sarajane Schwartz, required “thousands of hours” of collective labor and the expertise of “professional editors who live in the neighborhood and donated their time.” The wry narrative includes an overlaying of Stravinsky’s The Rite of Spring as doofusy tourists ride Segways, light up in hazardous areas and take nude pictures or pose with liquor bottles. THR was offered a rare screening of the closely guarded documentary: “We thought it would attract more people [if posted online] because it would just tell people where to go,” says Schwartz. “And we didn’t want it to end up on The Tonight Show — you know, making fun of us.”…

“There’s this privatization of public spaces in L.A., where people who are affluent expect to be insulated from the public,” says urban design professor Jenny Price, a visiting lecturer at Princeton and veteran of the Southern California coastal-access wars (she created the popular Our Malibu Beaches app, to David Geffen’s chagrin). “But the scandal here isn’t the wealthy homeowners. It’s the city’s complicity. Not just in getting permitted parking but in intentionally disseminating misinformation about a park they own. That’s the scandal.”

A fascinating story that raises important questions for cities: who gets to control access to public spaces? The sign is on public land (Griffith Park), streets are for the public, and yet wealthier residents want to control access and even knowledge disseminated on maps.

The article suggests the city needs a coherent plan:

Absent amid all the long-shot concepts are coherent, actionable steps to oversee access and shape tourism around a landmark. The city never has moved forward with clear plans to build a visitor center, properly control parking, manage trail access, strictly enforce rules (about smoking and alcohol, for instance) and inform visitors how to interact with the sign in a way that is satisfying and sensitive to residents. Imagine this type of chaos at the Statue of Liberty or Mount Rushmore (both are managed by the National Park Service).

Sounds like there is work to do to divert visitors, particularly if the city wants to respond to the wealthier residents while also keeping areas near the sign public (a visitor center just means people won’t really need to get that close).

Splitting America into equally proportioned states by population; options abound

Posted on by

Here is an interesting yet probably quite absurd set of maps that split the United States into various configurations of states with equal populations. Two of the maps:

140926_CBOX_Map4-EqualPopulation

140926_CBOX_MapCircles

I can see the logic behind this – more equal representation. However, the others are implausible. If anything, more equal populations might be accomplished by breaking states into smaller units that might be more equal in population to each other as pieces of the larger state. But, trying to imagine merging into megastates or different configurations of the 50 states is hard to imagine.

“City maps reimagined in the style of Tolkien’s The Lord of the Rings”

Posted on by

Here are some interesting maps of modern cities drawn in the unique style of the maps from The Lord of the Rings.

The two main differences that jump out to me:

1. The Tolkien-style maps tend to have more natural features. Modern maps are usually pretty devoid of hills and forests, unless they are major peaks or the land has been officially designated as a park or preserve. These new maps feature many more hills and forested areas that give some more indication of the natural setting.

2. Identifying communities with a marker of a few small houses suggests the metropolitan communities don’t run into each other. In other words, the markers suggest villages or hamlets separated by open space while American metropolitan areas have sprawling contiguous places.

The factors behind the rise of viral maps

Posted on by

Here is a short look at how viral maps (“graphic, easy to read, and they make a quick popular point”) are put together by one creator:

When I need to find a particular data set, it’s often as straightforward as a search for the topic with the word “shapefile” or “gis” attached. There’s so much data just sitting on servers that if you can imagine it, it’s probably out there somewhere (often for free). Sometimes though, finding data requires a deeper search. A lot of government-provided data sits inside un-indexed data portals or clearinghouses. Depending on the quality of the portal, these can be tedious to sort through…

Simplicity and ease-of-use: Interactive maps are great, but I want the maps I make to be straightforward to read and understand. I don’t want viewers to have to figure out how to use the map; they should just be able to look at it and figure out what’s going on.

Projections: Typical web maps are limited to the Web Mercator projection. I don’t have any objection to Mercator in principle (in fact it’s brilliant for what it does), but I can’t in good conscience use it for maps at a continental or global scale. Sticking to static maps allows me to choose more appropriate projections for the data and region I’m depicting.

Uniformity: I want everyone who visits my maps to be presented with the same information. I don’t want some algorithm deciding that one visitor is shown a particular view while another visitor gets a different one.

These principles sound similar to what one would expect for any sort of online chart or infographic. There is plenty of data available online but it takes some skill in order to present the data clearly and then market the map to the appropriate audience.

Now that I think about it, it is a little surprising that it took this long for viral maps to catch on. First, the Internet makes a lot of geographic data easily accessible. Two, it is a visual medium and maps are essentially graphics (audio is another story). Third, geographic data seems to feed into a lot of hot-button topics of conversation these days as people of different races (residential segregation), cultural viewpoints (think the American South or the Bible Belt), education (think the Creative Callas looking for exciting urban neighborhoods), and other groupings tend to live in different places.

I wonder if the real story here isn’t the technology that makes mapping on a large-scale relatively easy today. GIS software has been around for a while but it generally pretty expensive and has a learning curve. Now, there are numerous websites that offer access to data and mapping capability (think the Census or Social Explorer). Shapefiles are used by a variety of local governments and researchers and can be downloaded. There are good freeware GIS programs like GeoDa. You need some bandwidth and computing power to get the data and crunch the numbers. All together, the pieces have now come together for more people to access, manipulate, and publish maps in a way that wasn’t possible even just 5 years ago.

 

Liechtenstein losing the equivalent of a McMansion

Posted on by

The Wall Street Journal notes how the small country of Liechtenstein just got a little smaller, about the size of a McMansion.

Last month, Liechtenstein’s government said it altered its official map, part of a move to a more precise, satellite-based surveying system. The result: Bits and pieces amounting to about a quarter of an acre disappeared.

The land, cumulatively big enough for a McMansion, didn’t abruptly leave anyone living in a new country. So locals viewed the tweak as little more than a curious result of advancing technology…

The lost territory, which only shows up on the most precise technical maps, might have singed national pride or prompted a call to arms in some places. Not in Liechtenstein, a country of roughly 37,000 people who relish their homeland’s diminutive stature the way Texans prize enormousness.

This could lead to some discussions of how more precise mapping leads to boundaries changes like this. But, the comparison to a McMansion is more interesting here. If you had to make a size comparison, why choose a McMansion? The article notes that land lost was about a quarter of an acre. This is about 11,000 square feet. Is the suggestion that this is a typical lot size for a McMansion? One definition of a McMansion is a big house squeezed into a small lot such that the house dominates the lot. Is a McMansion too big for this space? Or, is a quarter-acre lot enough space for some lawn and a McMansion? McMansions themselves aren’t typically 11,000 square feet.

Statistics for new homes in 2012, averaging 2,505 square feet, suggest the average new home was built on a 15,634 square foot lot. Perhaps the better comparison in this article might have been this: the amount of area lost by Liechtenstein was less roughly 66% of the size of an average new house lot in the United States.

Crimean crisis for cartographers: is it part of Ukraine or Russia?

Posted on by

Maps today are updated often so Russia’s actions in Crimea have left cartographers with a decision to make:

Online mapping tools from Google and Bing, as well as Mapquest, all list Crimea as a part of Ukraine. Wikipedia’s community is embroiled in a fierce debate over whether or not to recognize Russia’s annexation of the region.

National Geographic still has not yet reached a decision on the matter, and is waiting for annexation to be formally approved. They said in a statement:

Most political boundaries depicted in our maps and atlases are stable and uncontested. Those that are disputed receive special treatment and are shaded gray as “Areas of Special Status,” with accompanying explanatory text.

In the case of Crimea, if it is formally annexed by Russia, it would be shaded gray and its administrative center, Simferopol’, would be designated by a special symbol. When a region is contested, it is our policy to reflect that status in our maps. This does not suggest recognition of the legitimacy of the situation.

Rand McNally, on the other hand, takes its mapping data from the State Department, and so will leave its data as it currently stands. It could be a long time before the U.S. formally recognizes Russia’s takeover.

It sounds like this comes down to: (1) which authority each cartographer relies on plus (2) the perceived legitimacy of Russia’s actions. While maps may simply reflect these political realities, they also have the potential to shape current and future perceptions of the area.

If only we could go back to the good old days (20 years ago?) where it took some time for maps to be updated. As a kid, I loved maps and I remember the shift in the early 1990s to a fragmented Yugoslavia (the National Geographic Geography Bee seemed to like focusing on this rapidly changing region as well) as well as emerging post-Soviet states. It takes some time for all these maps to be updated, from online sources to printed atlases to school textbooks and maps that hang on classroom walls. Cartographers in the past might have had more time to wait out a situation like this to see what happens while today people want the newest information now.

Super Bowl byproduct: first regional mass transit map for New York City

Posted on by

The Super Bowl prompted officials to put together a regional mass transit map for New York City for the first time:

Festivities for the big game are spread between Manhattan’s Times Square, Newark’s Prudential Center, and the MetLife Stadium in the Meadowlands. So getting around by public rail involves, depending on your route, the PATH, NJ Transit, the MTA subway, the Long Island Railroad or even Amtrak.

To make life easier, the New York/New Jersey Super Bowl Committee asked designer Yoshiki Waterhouse of Vignelli Associates to merge all the systems onto one diagram.

The result is the closest thing the New York City area has to an all-in-one rapid transit map. The host committee has been passing them out to fans and media and has made it available online. But if you’re a regular New Jersey to Manhattan commuter, or just a design fan, you should probably get your hands on one of one these before they end up as an expensive collector’s item.

While there are clearly a lot of things going on in this map, it doesn’t make much sense that this is the first full transit map. (Technically, it doesn’t include buses but that is another story.) Why might this be? One assumption could be that the average visitor or tourist isn’t terribly interested in leaving New York City on a typical visit. Plenty of visitors might want to go to Brooklyn but how many want to take a train to Long Island or the Prudential Center in New Jersey? Another answer could be that for trips within New York City, the city and others clearly see the subway as the only way to go because of its efficiency and coverage.
