The comprehensive plan highlights the time it takes to travel on foot between almost all of the stations on London’s Underground network.

According to NeighborhoodX‘s latest map the price paid for a Bed-Stuy or Harlem apartment could get you a pretty sweet pad in the South of France or even trendy Paris. — 6sqft.com

We all have a pretty good idea which NYC neighborhoods command top dollar, but this incredible 3D map from NeighborhoodX really puts things into perspective by pinning the city’s 325 neighborhoods against one another in a visually jarring side-by-side comparison. Among the most expensive? In Brooklyn... — 6sqft

So will Apple’s version of street-based imagery simply be a direct copy of Street View? Possibly not. A patent filed back in 2013 mentions “3D Position Tracking for Panoramic Imagery Navigation,” and the filing is disparaging of existing imaging software, calling it a “tedious experience,” though it doesn’t mention Google Street View by name. — venturebeat.com

Construction in Los Angeles may have exploded during the postwar era, but as a new interactive map shows, the wide age range of its buildings might surprise you.

Using open data from local governments, built: LA visualizes the age of roughly 3 million buildings across L.A. County constructed between 1890 and 2008. Drag your mouse to explore the vast web of communities and neighborhoods, hover over individual properties to discover birth years, and double click to zoom in further.   — citylab.com

Open data, and the interactive mapping and data visualization that can come of it, has become a de facto engagement and storytelling tool among contemporary journalists, social justice activists, and civic-minded technologists. But despite its allure, open data’s potential for fostering civic engagement and creating transparency and dialogue is plagued by issues of usability, access, and quality control. — urbanomnibus.net

This lively effort — mapping — is the subject of a rich exhibition organized by the Brooklyn Historical Society (BHS) and BRIC [...] that pairs the work of 18 contemporary artists with 23 historical maps dating back as far as 1562. For Mapping Brooklyn, BHS opened its collection to the invited artists [...]. The goal of uniting these two components — map and art — is to uncover the common ground: to render, through judgment and artistic process, the world legible. — urbanomnibus.net

Two months ago, after much lobbying by the biggest satellite company in North America, DigitalGlobe, the US government relaxed restrictions to allow for commercially available satellite imagery up to 25 cm resolution—twice as detailed as the previous limit of 50 cm [...] The extra sharp images from Worldview-3 will greatly increase the maps' level of detail to the point where it can make out 10-inch objects, which means Google will soon be able to see “manholes and mailboxes” [...] — Motherboard

But the intricate fantasy environments imagined for games like GTA V may well prove more useful than they seem. Now the technologies and tools developed by this multibillion dollar entertainment industry are making changes in the real world.

John Isaacs, a lecturer in computing at the University of Abertay, is one of those exploring the possibilities of game engines. In 2011, he developed an urban mapping application for his PhD project. — theguardian.com

There are more than 3,000 active oil and gas wells in Los Angeles County. Almost 4,680 new wells were drilled in 2012 across the state, bringing the total number to 210,000, according to the Division of Oil, Gas and Geothermal Resources of the California Department of Conservation [...] Oil industry officials argue that drilling in California provides many economic benefits, and they downplay any potential health hazards. — LA Daily News

Architects are the highest paid group of designers, and they are also generally the most highly educated. Architects employed in firms earned median hourly wages of $35.30, while their self-employed counterparts earned $22.90. But, when looking in terms of concentration, the nation’s leading clusters for architects may not be what you think. — citylab.com

A Finnish company called IndoorAtlas has figured out that all buildings have a unique magnetic “fingerprint” — and has solved how to use that to determine locations inside a structure to within six feet. That is enough to take a consumer to a product in a crowded supermarket, or figure out the location of, say, a half-dozen workers in a building full of them. It’s also much better than cell phone towers can do. — bits.blogs.nytimes.com
