Launching the Facebook Map

Jodah Adkins from Stamen Design:

For the past year and a half, it’s been our privilege to work on one of our largest and most ambitious undertakings ever: collaborating closely with a team of Facebook engineers, designers, and data experts to roll out a global, multi-scale base map for all of Facebook’s billions of users. In late 2020, this map went live, and we’re extremely proud of the results.

Always in for a good map, so definitely for this behind the scenes look!

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).

Mapbox Landsat-live

Today we’re releasing the first edition of Landsat-live, a map that is constantly refreshed with the latest satellite imagery from NASA’s Landsat 8 satellite. With every pixel captured within the past 32 days, Landsat-live features the freshest imagery possible around the entire planet.

Uses the Landsat 8 data directly now that it’s stored on AWS.

GLMap Framework


GLMap is a lightweight offline map component with a simple mechanism of integrating into any iOS or Android application.

With the GLMap framework, map data is prepared on CPU and is rendered directly on GPU using OpenGL ES 2.0. This allows each processor to do the job it does best. By splitting up data processing, we save CPU capacity for other tasks.

Vectors generated from OpenStreetMap data.

U.S. Midterm Elections 2014 Maps


Why are we so confident these are the most detailed maps you’ll ever see from the 2014 Senate elections? Precincts are the smallest level of geography for publicly-reported election results. There were more than 175,000 precincts in the United States in 2012, fifty times the number of counties. The maps here show precinct-level results, where available, from some of the closest Senate races.

Yes, those are zoomable. Built using D3.js and TopoJSON by @mbostock himself.

MapIt – Map geographical points to administrative areas


MapIt is useful for anyone who has the co-ordinates of a point on Earth, and who needs to find out what country, region, city, constituency, or state it lies within. It’s also great for looking up the shapes of all those boundaries.

Above is a screenshot using the coordinates of my hometown Deinze. Data also available as JSON. Defaults to EPSG:4326 (WGS84), but that also can be changed.

Open Source Routing Machine (OSRM)


The Open Source Routing Machine (OSRM) is a C++ implementation of a high-performance routing engine for shortest paths in road networks. It combines sophisticated routing algorithms with the open and free road network data of the OpenStreetMap (OSM) project. OSRM is able to compute and output a shortest path between any origin and destination within a few miliseconds.
