Pretty fascinating article in the New York Times about how our facebook social networks are distributed. Turns out state lines do seem to matter, unless you live in say Manhattan or DC.

You can go to the map and click on any county in the US and see the relative likelihood that your county is connected to any other county. The darker the color, the greater the likelihood.

Below are Allegheny County’s stats. Not at all shocking, but I was hoping to see a bit more on the Steeler Nation diaspora. Although we are pretty heavy in Florida.

Share of friends who live within …

50 miles: 62%, 100 miles: 65%, 500 miles: 88%

Pipeline Map, Fractracker

12 Sep

As everyone knows, there was a pipeline explosion in Beaver County over the weekend, a mere 30 miles from Pittsburgh. The pipeline was one week old

Thanks to Fractracker, we have a map of all of the pipelines in the state of Pennsylvania.

You can click around the map and see things such as who owns and operates a particular line, natural gas spills and incidents, where the pipelines cross waterways and wetlands, among other useful info.

According to the site, “pipeline data is published from a variety of public agencies, although almost none of it is really accessible or accurate.” “While they do not publish gas pipelines, they do have a 2012 dataset of natural gas liquid routes, which is a significant portion of the hazardous liquid inventory. From an analytical point of view, however, this dataset is essentially worthless. Many of these pipelines are so generalized that they don’t make a single bend for multiple counties, and the actual location of the routes can be miles from where the data are represented. Communities cannot use this as a tool to better understand how pipelines interact with places that are important to them, like schools, hospitals, and residential neighborhoods.

Pretty fascinating map of a different kind of pollution: noise. This shows the relative decibels surrounding airports and highways. Yellow to red to blue gets louder and louder.

See the whole map of the entire United States here.

Basically, only Maine looks cool.

During the bike boom of the late 1800s, the Pittsburgh Press apparently published some recommended bicycle routes and maps to get people riding these new velocipedes. This one is a century ride from Pittsburgh to New Castle along the Ohio River.

Looking forward tracking down the other “Popular Bicycle Routes” of the 1800s.

Trolley lines that survived to the end of 1957

28 Aug

Someone made a Google Map of every trolley line in the US that survived to the end of 1957.

Here’s a screencap of Pittsburgh.

In 1956, the Pa. General Assembly consolidated the companies by creating the Port Authority of Allegheny County, which transitioned from streetcars to buses, mainly to save money in operations and maintenance, per WESA.

See the full map here.

Once there, you can click on a line for more info and abandonment dates.

Then you can cry.
