When geolocation makes everyone think you stole their phone

People show up unannounced at John and his mother Ann’s home in South Africa, looking for stolen property, but John and Ann didn’t steal anything. For Gizmodo, Kashmir Hill investigates another case of IP address and geolocation mistaken for exactness: John and Ann’s problems weren’t necessarily caused by one bad actor, but by the interaction of a bunch of careless decisions that cascaded through a series of databases. The NGA...

Skewed mental map of the world’s geography

The maps that we imagine as we think about locations around the world often don’t match up with reality. Betsy Mason for National Geographic explains the discrepancy.

But it actually lines up better with Canada: Paris is further north than...

Comparing Google Maps and Apple Maps Over a Year

Google collects much of their own data to construct their maps, whereas Apple sources most of their data externally.

Justin O’Beirne took monthly screenshots for a year to look at the differences more closely. Tags: Apple, cartography, Google

Glow map

John Nelson has a knack for making maps that glow, where the base map serves as a dark backdrop and the data of interest sort of lights up.

Thematic layers that look like they are etched...

Maps to understand tennis

Damien Saunder, a cartographer at ESRI, likes to use mapping methods to evaluate tennis player patterns and tendencies. When I look at tennis, I see it moving on a grid. I see space and x/y coordinates [position] and I see z values [height], and I see trajectories of the balls, and space opening up. I started GameSetMap to try and educate people of the value of mapping where people are...

Quick reference guide to thematic cartography

Mapping data is so much about subtleties. The little things add up to make a full map exponentially better than one that wasn't given the proper attention.

In this short guide we share some insights and tips for making thematic maps. Our goal...
