Constantine Valhouli-NYC Property Prices-Hand Drawn Map

Map makers Constantine Valhouli and Cat Callaghan have been behind some of the Fun Maps we’ve featured on Untapped Cities, like tracking the Beat Generation and mapping every song referencing  NYC. For his latest work, Valhouli tells us he was hoping to take a break from the typical heat map to show “in a more accessible way how New York City housing prices are really disparate,” and how there are “surprising pockets of affordability” that show up using this type of map versus a more conventional visual format.

The maps include both hand-drawn and digital versions with the height of each neighborhood’s section representing the cost of property per square foot.  (more…)

As we all know, real estate prices just keep on rising in Manhattan. And to whom are developers turning to find the prime location for their next high rise condos? Gas stations. Historically, gas stations are on street corners and along major roads for easy access, and the small amount of actual structure is easy for developers to take down. Real estate prices are so high that it’s starting to make sense for owners to sell the valuable plot where the gas station was for more money than they would make off of the gas itself.

Heat Map-Illegal Apartments Dwellings-NYC-SITU Studio-311 complaints-Department of BuildingsHeat Map of Illegal Dwelling 311 Complaints by SITU Studio

Although New York City has come a long way from the tenement days of yore, it still faces problems of illegal housing. In a city as dense in New York, the modern slum isn’t something low-rise and set apart from the rest of the urban fabric–it exists within our buildings. At a new exhibition at the Museum of Modern Art, Uneven Growth: Tactical Urbanisms for Expanding Megacities, design firm SITU Studio created an urban heat map of 311 complaints to the NYC Department of Buildings for illegal dwellings. There’s no official number, with the complaint data “the only real indicators,” as SITU Studio partner Basar Girit tells Fast Company.

Day Glo Map-Steven Van Worley-NYC Street Grid-001

Artist and scientist Stephen Von Worley made these incredible “day glo” maps of a handful of the world’s major cities ostensibly to understand in his own words, “what other treasures I had missed.” The result from a data visualization standpoint is to give us an idea of how gridded a city is. A basic rundown of how these beautiful maps work: the roads that are oriented in the same direction have the same color. The thicker the lines, the more “grid-like” the area is.

Manahatta-Map-Eric Sanderson-Markley Bower-NYC

You probably remember this image from 2009 but we thought we’d bring back the TED Talk that explains how landscape ecologist Eric Sanderson and illustrator Markley Boyer recreated what Manhattan looked like when English explorer Henry Hudson arrived in 1609. They used a British military map from 1776 to visualize the what existed on the island the Lenape called called Mannahatta. In order to deduce which ecosystems existed on the island pre-1609, Sanderson isolated the geographical elements from the 1776 map, studied the types of soil, rock, and climate of the different regions, and from there, the species of animal, fish, and plant life that corresponded to each habitat.

We’re always on the look out for fun maps of NYC and we came across this site recently, NYC Roads by Steve Anderson. It looks like it was laid out in the 1990s but it does have a nice archive of road maps, vintage photographs and more. The road map database goes from 1928 to the 1990s. Here are some highlights:
