Unfolded Studio — Geospatial Data Reinvented

A geospatial analytics platform for data unification, enrichment, and visualization.

It’s built on top of the aforementioned deck.gl and Kepler.gl

Sidenote: By the looks of it, the open-source Kepler.gl is doing the heavy lifting there.

Google Maps Hacks: Creating a Virtual Traffic Jam

Google Maps Hack by Simon Weckert:

99 second hand smartphones are transported in a handcart to generate virtual traffic jam in Google Maps. Through this activity, it is possible to turn a green street red which has an impact in the physical world by navigating cars on another route to avoid being stuck in traffic.

Hah, Brilliant!

The Spilhaus “World Ocean Map in a Square“ Projection

Coming to the next version of ArcGIS is the “Spilhaus projection”:

In September and October of 2018, three maps went viral on social media and the web. All of them had the same perspective, featured oceans as the main focus, and presented the oceans as one body of water. The maps were based on the so-called “Spilhaus projection” and centered on Antarctica. Though it has recently gained some popularity online, this projection is not new. Many articles recognize Athelstan F. Spilhaus, a South African-American geophysicist and oceanographer, as the author of this projection back in 1942.

Over at the ArcGIS blog they outline the history and how they’ve implemented it in their next version (ArcGIS Pro 2.5 / ArcGIS 10.8).

MapItOut: “How far could I live from X?”

The folks at IAmsterdam have released a map that measures distances not in miles / kms but in time. Select a spot + a means of transportation + a desired travel time and it’ll show you how far away (in time) you can get.

From what I can tell European countries such as Belgium, France, Germany, etc. are also supported but New York (USA) and London (UK) for example aren’t.

Peak Map

Peak Map allows you to visualize elevation of any area on the map with filled area charts (also known as a ridgeline)

Think of Joy Division’s famous “Unknown Pleasures” album cover, but then as a map of the world.

What surprised me is that here’s no set of pre-generated custom map tiles, but they are instead generated on the fly

I’m using MapBox GL to draw the map. Once the area is selected, I’m using elevation data API from the MapBox.

The rendering of the lines is done on canvas overlay, using regular 2D canvas context.

Mercator – It’s a flat, flat world!

In the 16th century, Gerardus Mercator, a Flemish cartographer devised a new way of depicting the world on a flat plane. We set off to explore his map in order to illustrate his biggest blunders, unearth curious facts and explain the advantages that make this representation of the globe still relevant today.

I especially like the fact that the several parts of the map get highlighted as you scroll, thanks to the use of ScrollMagic

📜 If you’d want to venture into your own “animate as you scroll” adventure, I’d recommend a more modern library such as the aforementioned Scrollama (which uses IntersectionObserver)

🗺 In case you want to see for yourself how much Mercator distorts our view of the world, go play The Mercator Puzzle. In case you’re really into projections you might want to check out the contents of my talk Geoshizzle (from a long long time ago)

🌍 If you’re new to mapping & projections, or don’t want to read the lengthy article, this video from Vox sums it up quite nicely what’s wrong with the Mercator projection:

Inuit Cartography: A Coastline Map Carved out of Driftwood

In Kalaallit Nunaat (Greenland), the Inuit people are known for carving portable maps out of driftwood to be used while navigating coastal waters. These pieces, which are small enough to be carried in a mitten, represent coastlines in a continuous line, up one side of the wood and down the other. The maps are compact, buoyant, and can be read in the dark.

Can you spot a Map Trap?

Not your typical map: “Where is all the poop on the moon?”

Ever wondered what the astronauts that landed on the moon did with their waste? Well, they ditched them on the moon itself.

It’s been nearly 50 years since the Apollo 11 moon landing. Neil Armstrong’s iconic footprint is still there, undisturbed; there’s no atmosphere, no wind on the moon to blow it away.

But the bigger human footprint on the moon is, arguably, the 96 bags of human waste left behind by the six Apollo missions that landed there.

Yes, our brave astronauts took dumps on their way to the moon, perhaps even on the moon, and they left behind their diapers in baggies, on humanity’s doorstep to the greater cosmos.

Just look at the big white bag right underneath the lunar lander:

👨‍🚀 That’s not all what’s been left on the moon. If you were to land on the moon, you’d also find Hammers, Earplugs, Batteries, Camera Systems, etc. Check out the full Catalogue of Manmade Material on the Moon (PDF) (with coordinates) if you’re interested. The catalogue is from 2012, so SpaceIL’s crashed Beresheet Lander is not included on it.
