The Blocked Arteries of America's Roads


Metrocosm has created an interesting animated map of 24 hours worth of traffic on the U.S. Interstate Highway System. The US Highway Map visualizes an average day's traffic on the highways by hour of the day.

The simple visual metaphor used in this map is that the U.S. Interstate Highway System resembles the human circulatory system. As the map plays through an average day's traffic you can observe how the arteries become blocked at times of high road usage.

The data for the map is from the Department of Transportation. The map itself was custom made in WebGL with a little help from Three.js and D3.js. The map is actually in 3d so, if you want, you can rotate the map by left clicking on the map and dragging it around. You can also use your mouse's scroll wheel to zoom in & out on the map.

Play the 2016 Ryder Cup on Street View


If you can't wait until Friday for the 2016 Ryder Cup to begin then you might want to whet your appetite by exploring the complete Hazeltine National golf course in Street View.

Google Maps, Ubilabs and Turner Sports have collaborated to create a truly impressive immersive tour of the course. The Hazeltine Explorer provides you with a first hand experience of all 18 holes of the Hazeltine National and allows you to virtually explore the tees, fairways and greens on Google Maps Street View.

You can use the Hazeltine Explorer Google Map, showing a satellite view of the course, to navigate to any hole on the course. Click on a hole number on the map and you can explore the hole, from tee to green, using Google's 360 degree panoramic imagery. The Hazeltine Explorer also includes a video flyover and a short description of all 18 holes. There is also an audio guide to each hole, with a few tips on how the Ryder Cup players might approach playing each hole.

The Great Smoky Mountains Species Map


The Great Smoky Mountains National Park is home to over 1,800 different plant and animal species. You can now view where the park's different animals and parks live on a new interactive map of the park.

The Great Smoky Mountains National Park Species Mapper allows anyone to view the distribution of plant and animal life in the park. It provides a tool for park managers to protect life in the park and assess the impact of different species on other life in the the park. It also provides a handy tool for visitors to explore what they might see when they visit the park.

You can use the drop-down menu to select a species to view on the map. You can also select to compare the distribution of the selected species with one or two other plants or animals. Alternatively you can choose to compare your selected species with other species which share a similar distribution in the park.

Mapping Global Air Pollution


Air pollution causes 1 in 8 deaths worldwide. To help fight this invisible killer the World Health Organization has launched the BreatheLife campaign. The campaign advocates key changes that governments around the world can take to reduce sources of climate-harmful air pollutants.

The World Health Organization's Global Ambient Air Pollution map shows the levels of pollution across the globe. The map displays the average annual atmospheric particulate matter levels throughout most of the world. The data used is from the WHO Global Urban Ambient Air Pollution Database, which covers 3000 cities in 103 different countries.

The Global Ambient Air Pollution map helps highlight the fact that air pollution most effects those living in low and middle income countries. However 56% of cities in high-income countries also don't meet the WHO air quality guidelines. Even in high-income countries Urban air pollution levels tend to be higher in low and middle-income cities and in the poorer neighborhoods of high-income cities.

The Underground Sound of America


Underground Sound is a series of four interactive maps exploring some of the lesser known music venues in San Francisco, Los Angeles, Chicago and New York City.

Choose any of the four cities and you can discover some of the best local music venues, as chosen by Mic. The location of each venue is displayed on a custom styled Google Map. If you select a venue from the map you can view details about the club in the map sidebar, including a brief description of the club, its address, website and a link to a review of the club on Mic.

35,000 Marathon Runners Mapped


Over 35,000 people completed yesterday's Berlin Marathon. You can see how every one of those competitors fared in an animated map of the race, created by the Berliner Morgenpost.

The Berlin Marathon 2016 map animates every single runner in the Berlin Marathon on top of a map of the race's route. As the animation plays out you can watch all 35,827 of the athletes as they complete the course.

Buttons at the bottom of the map allow you to filter the runners shown on the map by gender. You can also filter the runners shown on the map by the home town of each competitor. So, for example, if you want to see how the 23 runners from San Francisco fared in this year's Berlin marathon you just need to type 'San Francisco' into the map search box. The runners from San Francisco will then be highlighted on the map. The average time of all the runners from San Francisco will also be displayed on the map.

The animated map of the Berlin Marathon 2016 was created using the PixiJS HTML5 engine.

Time Travel Around the World


OldAms is a new website which allows you to view thousands of vintage photographs of Amsterdam on an interactive map of the city. The map geo-locates old photographs of Amsterdam from the Amsterdam City Archives.

OldAms includes a slide control which allows you to filter the photographs displayed on the map by year. This allows you to set a date range for the age of the photographs you wish to view on the map. When you select a marker on the map thumbnails of the selected image(s) are shown in the map sidebar. You can then click on these thumbnails to view a larger version of the vintage photo.


OldAms is inspired by the OldSF website. OldSF is an interactive map which allows you to browse historical photos from the San Francisco Public Library collection. OpenSFHistory has also created an interactive map of over 100,000 vintage photos of San Francisco from the Western Neighborhoods Project.

The same team behind OldSF also created OldNYC, OldNYC is a Google Map locating 80,000 historical photographs of New York from the wonderful Digital Collections of the New York Public Library.

In London you can use the Collage map to browse over 250,000 images of the city from the collections of the London Metropolitan Archives and Guildhall Art Gallery.

You can also step back in time in Norway using the Tids Maskinen (Time Machine) map. This Google Map allows you to browse vintage photos of Norway by location and date.


If your home town isn't featured in any of the above maps then you should try the Historypin map. Historypin is perhaps the most well known map of vintage photographs.

This map archive allows anyone to add historical photographs to an ever growing map of vintage photos from around the world. Because Historypin allows anyone to add historical photos to their collection they have thousands of vintage images of locations across the globe.

The Maps of the Week


The Berliner Morgenpost is a creator of consistently great mapped visualizations. Their map of last week's Berlin election is another superb example of how spatial data can be presented and analysed on an interactive map.

The 2016 Berlin Election map shows the election results in every electoral ward in the city. If you click on a party name in the map legend you can also see the ten districts where that party got its highest share of the the vote. For example, if you click on 'AfD' you can see that the anti-immigration party got its biggest share of the vote in seats which were in the old East Germany.

You can view the Berliner Morgenpost's analysis of the vote by using the links running along the bottom of the map. The 'Rechtruck' link, for example, shows a choropleth view of the AfD's vote share across the capital. This shows that the party actually performed reasonably well across the whole city and only failed to get below 5% of the vote in 33 of the 653 electoral areas.


This week also saw the release of a new travel time interactive map, from Urbica, called Galton. The map can help you discover how far you can walk or drive in ten minutes within major cities around the world.

To find out how far you can walk or drive in ten or twenty minutes you just need to move the black dot on the map to the starting point of your journey. The dark blue area will then show you how far you can walk (or drive) in ten minutes. While the light blue area shows where you could walk in twenty minutes.

The travel time algorithm used by Galton uses the Open Source Routing Machine with OpenStreetMap map data to work out the travel time distances. The project code of Galton is open and available on GitHub. You can also learn more about Galton and how it was developed on the Urbica blog.


Dark Sky provide hyper-local weather information with its iOS and Android apps. It also provides a desktop weather map which includes a seven day forecast of weather conditions around the world.

The Dark Sky Weather Map provides the option to view global weather conditions on an interactive 3d globe. The map includes a number of different weather layers which allow you to view a seven day forecast of temperature, precipitation and wind speed around the world.

The Dark Sky 3d weather visualization uses OpenLayers with the Cesium WebGL 3d globe engine. The Dark Sky Weather Map also includes an option to embed the weather map and 3d globe on your own website or blog.

Mapping Gentrification in New York


Earlier this year the NYU Furman Center released a report into Gentrification in New York City (PDF). The report examines how increasing rents and stagnating incomes have contributed to the gentrification of nearly two-thirds of the city's previously low-income neighborhoods.

The result of this gentrification of New York is that many residents are paying more in housing than they can easily afford. The Association for Neighborhoods and Housing Development has decided to help raise awareness of "where residential tenants may be facing significant displacement pressures and where affordable apartments are most threatened across New York City".

The association's Displacement Project Alert Map provides a building by building assessment of where residential tenants may be facing significant displacement pressures. Individual residential buildings are color coded on the map to show the displacement risk level for residents living there.

The DAP map provides a number of displacement risk level scores for New York residential buildings. These risk scores are based on the loss of rent regulated units, the volume of Department of Buildings work permits and the level of property sales tax. The map also provides a combined score for each building based on these multiple combined risks of displacement.

The Car Shaming Map


Every cyclist knows the dangers of cars parked selfishly in bike lanes. They have all also experienced the frustration from knowing that there is nothing that you can do about it. Except if you live in New York.

A new website allows New York cyclists to publicly shame car drivers who park in bike lanes. carsinbikelanes.nyc allows anyone to submit photos of cars obstructing bike lanes. It then displays the photos of the offending vehicles on an interactive map. It also prominently displays the licence plates of the obstructive cars.

If you don't live in New York then you could always fork the project on GitHub and set up your own crowd-sourced traffic violation reporting map in your own city or town.
