I’ve been hoping to tinker with Github’s new mapping service since the company announced it earlier this month. Turns out it’s quite easy. You just commit a GeoJSON file to your repo, and voilà.
The points on this simple map represents the location of each car2go I’ve rented (excluding those in Austin, Texas). Surprise, they’re mostly clustered in our neighborhood:
This is a simple as it gets. The service also allows other data types, like polygons, for example. Tomorrow I’ll try a more interesting data set, maybe DC property parcels or 311 calls locations. And I’ll experiment with the Github docs to see how I can customize the icons and design. We’ll see…
BTW: Github is using MapBox to create its custom map base layer. Read more about that here. And thanks to my co-worker, Chris Groskopf, whose csvkit suite makes it super easy to convert basic data files into GeoJSON.
The U.S. Census Bureau recently released estimates for insurance rates by county. This interactive map shows those rates, with darker shades representing higher uninsured rates:

Our latest work project transforms the static federal wildfire danger forecast into an interactive map. We released it today:
Users can view the full country map or find their location to see burning conditions in their area, in this case Carthage, Missouri:
And it works on a smart phone or tablet:
NPR and the Center for Public Integrity have teamed up for a series of this stories this week about facilities that emit toxic chemicals. One part of the package is this interactive map, which plots more than 13,000 regulated facilities across the country — and also colors the dots based on the potential risk to people living around them:
See a larger interactive version of the map, which was created with Development Seed’s TileMill application and hosted on its MapBox service.
The White House today released an interactive map of excess properties maintained by the federal government. And, even better, it appears they made it with open-source tools. An explainer:
The Federal Government is the biggest property owner in the United States, and billions of taxpayer dollars are wasted each year on government properties that are no longer needed…. There are roughly 14,000 buildings and structures currently designated as excess and thousands of others that are underutilized. These properties range from sheds to underutilized office buildings and empty warehouses. Over 7,000 of these properties are plotted on this map, zoom in to see Excess Properties in your state and around the country.
You can zoom into a state or specific property and also download the data set. In this view, proportional symbols represent excess properties:
