Left: using traditional raster images; Right: Using vector tiles with higher resolution. Moji Weather, the creator of China’s largest weather app, visualizes radar data, AQI (Air Quality Index), and other weather conditions with Mapbox GL for its Android and iOS apps. Radar data are among the most difficult to render quickly on native apps — Moji Weather realized this challenge and reached out to
By: Ben Levin We’ve partnered with Zenrin, the leading provider of Japanese map data since 1948, to bring enhanced map data to our services for Japan. Mapboxは、1948年創業の日本地図データ大手プロバイダーであるゼンリンと提携し、日本向けMapboxサービスのマップデータを拡張しました。 Zenrin has more than 1,000 surveyors and 70 years of experience mapping Japan. Their data covers 99% of all Japanese roads and neighborhoods. This has improved our coverage in
By: Peter Liu How would you describe your morning commute? If you’re like most people, it starts with a ballpark estimate of how long it usually takes. Or maybe several estimates, depending on when you leave for work, how bad traffic is, or whether you’re walking, driving, or taking the bus. There’s something strange here: we’re answering a question about a trip through physical space, with number
A visualization of an R-tree for 138k populated places on Earth I’m obsessed with software performance. One of my main responsibilities at Mapbox is discovering ways to make our mapping platform faster. And when it comes to processing and displaying spatial data at scale, there’s no concept more useful and important than a spatial index. Spatial indices are a family of algorithms that arrange geom
The Mapbox platform is powered by Amazon Web Services — specifically, most of our computing workloads run on AWS EC2. We’re in the process of wrapping up a company-wide migration (led by the Platform team) onto Docker, hosted on AWS ECS (EC2 container service). Here’s what we’ve achieved by containerizing any and all of our computing needs: 1| Lower AWS bills. By switching to ECS we cut our EC2 bi
By Baran Kahyaoglu The Niantic team, creator of Pokémon Go, did amazing work in creating an iconic map style as a canvas for its game. Here’s how to build a map for location-based games with additional detail like buildings with the Mapbox Unity SDK and Unity. 1 Design in Mapbox StudioFirst we used Mapbox Studio to design a base map highlighting roads in dark green with yellow casings, water bodie
By Vladimir Agafonkin We came up with a neat little algorithm that may be useful for placing labels and tooltips on polygons, accompanied by a JavaScript library. It’s now going to be used in Mapbox GL and Mapbox Studio. Let’s see how it works. The problemThe best place to put a text label or a tooltip on a polygon is usually located somewhere in its “visual center,” a point inside a polygon with

By Vladimir Agafonkin Last year, I explained how we use dynamic shape simplification and partitioning algorithms to render huge polygon and polyline datasets in Mapbox GL JS. This approach unfortunately doesn’t work for individual points: so how do we display hundreds of thousands of points in a meaningful way on a map? Mapbox GL JS recently got a new feature to address this — point clustering. Le
By John Firebaugh Starting today, Mapbox maps can be used without a data connection. The Mapbox Android and iOS SDKs can now pre-cache maps to save bandwidth and data charges, optimize performance, and anticipate lack of network access. Imagine: A delivery app that pre-caches maps to the pick-up, ensuring that you’ll get to your destination even if you drive through an area without cell coverage.A
By Konstantin Käfer Maps are mostly made up of lines, as well as the occasional polygon thrown in. Unfortunately, drawing lines is a weak point of OpenGL. The GL_LINES drawing mode is limited: it does not support line joins, line caps, non-integer line widths, widths greater than 10px, or varying widths in a single pass. Given these limitations, it’s unsuitable for the line work necessary for high
By Eric Fischer The Geotaggers’ World Atlas is my long-term project to discover the world’s most interesting places and the routes that people follow between them. Five years ago I first started retrieving photo locations from the Flickr search API and drawing lines between them to make the first version of the Atlas. A cluster of geotagged photos is a good indicator of the interestingness of a pl
By Eric Fischer View more cities View full screen map Ben Fry’s classic map of the United States, “All Streets,” demonstrated that a complete map of streets also implicitly creates a map of the topography around them, because the form of the land determined the locations of the roads. Few places in the world show this effect as strongly as Japan, where intensive urbanization constrasts sharply wit
By Paul Goodman This quick shot by Skybox’s SkySat-1 shows multiple planes landing at Beijing Capital International Airport (PEK) airport in Beijing on December 30, 2013. You can easily see a large plane landing on the runway at right. Using the video’s timestamp and public flight logs, Bruno identified this plane as Air China Limited flight 1310, a wide-body Airbus 330 flying from Guangzhou to Be
By Eric Gundersen This is a look at 3 billion tweets — every geotagged tweet since September 2011, mapped, showing facets of Twitter’s ecosystem and userbase in incredible new detail, revealing demographic, cultural, and social patterns down to city level detail, across the entire world. We were brought in by the data team at Gnip, who have awesome APIs and raw access to the Twitter firehose, and
Vector tiles support the rendering, delivery, and data access requirements of the vast majority of map publishing applications. Vector tiles can encode arbitrary data at world scale, render it on a client quickly, and allow you to only pay for the data created, reducing the need to manage complex tiling and application servers. This is why vector tiles are suitable for hundreds of thousands of cus
By Saman Bemel Benrud Today we are announcing the launch of ideditor.com, home of the web-based OpenStreetMap editor iD currently in Alpha phase. This launch marks our stepped up involvement in the development of this editor. iD is designed to help create an even better, more current OpenStreetMap by lowering the threshold of entry to mapping with a straightforward, in-browser editing experience.
By Young Hahn This is a transcript of my Rendering the World session for anyone who was not able to attend the FOSS4G conference. This transcript is based on my memory and is not a recording so there may be differences from the actual presentation. My name is Young Hahn. You can follow me on twitter or on GitHub. Today I’m going to be presenting not just my work but the work of my colleagues: AJ A
