Who Moves Where in Europe?

In Europe citizens of countries in the EU and the European Free Trade Association (EFTA) are free to live, study, work and retire in any other EU or EFTA zone country. Swissinfo has been looking at the effect of free movement on the net migration rate in each of the countries in the EU & EFTA.

Which European countries attract the most immigrants? shows the difference between the number of immigrants and emigrants in each country based on movement within the free movement area. Areas with a positive net migration rate (where more people are moving to) are colored blue on the map and areas & regions with a net migration rate (where people are leaving) are colored brown on the map.

As you might expect migrants within Europe tend to move to regions that have the strongest economies. Conversely the areas and regions where the most people move from tend to be areas with weaker economies.

This map is featured in Swissinfo's 'migration' series. This in-depth series explores the issues of migration around the world (particularly in how it effects Switzerland) and includes a number of maps and other data visualizations of global and European migration data.

Friday's Portrait of Earth

Japan's Himawari-8 satellite is in stationary orbit over New Guinea where it captures some truly amazing imagery of the Earth. Every day the satellite captures imagery of the western Pacific, Australia, and parts of Asia, Antarctica & Alaska.

Digital Typhoon's Weather Satellite Himawari Viewer is an easy way to explore the latest satellite images from Himawari and explore historical Earth images captured by the satellite. The viewer takes the latest satellite images of Earth captured by Himawari and displays them as an interactive Leaflet map. This allows you to zoom-in and pan around satellite images of the Earth which were actually captured earlier today.

You can also view time-lapse animations of the latest Himawari-8 satellite imagery, on Himawari-8 Real-time Web. Himawari-8 Real-time Web defaults to create and show animations of Himawari's latest satellite views of Earth. You can also use the calendar to view historical imagery and animations for any other date.

The Atlanta Rap Map

According to the Syncopated Geography of Hip-Hop "the sounds of rap music in Atlanta have grown out of the blending of hard-core sounds from the West (Gangsta Rap and G-Funk), bass beats from Florida, and styles and images from the North". The sounds of rap music in Atlanta were also hugely inspired by the city of Atlanta itself.

The introduction to the Atlanta Rap Map says that the map explores "the symbiotic relationship between art and space". In essence, however, this is an interactive map showing Atlanta locations mentioned in the lyrics of Childish Gambino, Ludacris and OutKast.

The map provides a great resource for exploring the places that are important to each of the featured three rap acts. If you click on the categorized markers on this map you can read the lyrics that mention the location and the name of the Childish Gambino, Ludacris and OutKast song that mentions the place. The map really does show "the symbiotic relationship between art and space". In fact I think I can even tell where the three rap acts grew up in Atlanta purely from the clusters of the three different colored markers on the map.

The Pudding analyzed the lyrics of about 50,000 songs in order to discover the most common words used in Hip Hop. From this analysis they were then able to make an interactive map which groups Hip Hop artists by lyrical similarity.

The Words That are Most Hip Hop interactive map organizes the faces of Hip Hop artists based on the overlap between the words they use in their lyrics. You can hover over the faces on the map to reveal the name of each artist. The map reveals distinct etymological families in Hip Hop. For example there is the Wu-Tang branch of the language of Hip Hop whose members share a very similar lexicon.

The different dialects of Hip Hop that emerge on the map may owe a lot to the physical geography of the Hip Hop artists. Further study is needed to see if the lyrical similarity between artists correlates to geographical closeness. The Atlanta rap artists Childish Gambino and Ludacris are quite close to each other on the map and OutKast aren't too far away.

To prove a link between Hip Hop dialects and geography you might want to explore the Geography of Hip-Hop interactive map. The Geography of Hip-Hop documents the history and geography of Hip Hop. The map (and accompanying essay) explore how Hip Hop has spread around the world and how different cites have developed their own distinct sounds and styles of Hip Hop.

The interactive Hip Hop map allows you to browse and listen to Hip Hop music by location. The map features 955 songs, most of which you can listen to directly from the map. The size of the markers on the map reflects the number of artists featured from that location. In this way you can get a rough idea about the size of the Hip Hop communities in these different urban locations.

By listening to the songs listed in one city you may begin to get a feel for the sound and style of Hip Hop from that location. You can learn more about the development of Hip Hop in the accompanying essay, The Syncopated Geography of Hip-Hop. The essay explores the influence of geography on Hip Hop communities & styles and how Hip Hop music reflects the influence of the different urban locales where it is made.

The 2018 World Cup Stadium Tour

12 stadiums in 11 Russian cities will host the 64 matches of the 2018 World Cup. Two of the stadium are in Moscow. The 81,000-capacity Luzhniki Stadium will host the final. The Luzhniki Stadium will also host today's opening match between Russia and Saudi Arabia. The other World Cup stadium in Moscow is the 45,000 Spartak Stadium.

You can explore the two Moscow stadium and the ten stadium hosted in other Russian cities on AP News' World Cup Venue Tour. The tour uses Esri maps to show you a satellite image of each of the 12 World Cup stadium. Each satellite image is accompanied by a short description of the stadium, including information on the stadium's capacity.

The BBC's Guide to the Grounds includes more detailed information on each of the stadium. These details include information on each of the group and knockout matches that each of the stadium will host.

The Kalingrad Stadium is one of the most interesting of the 12 stadium from a geographical point of view. The stadium is located in the Kaliningrad oblast. Kalingrad is a Russian exclave situated on the Baltic Sea. The country is bordered by Poland to the south and Lithuania to the east and north. That means that to travel to the Kalingrad Stadium from any of the other stadiums you would have to leave Russia and travel through or fly over or around at least one other country.

From a cartographical point of view the most interesting team in this year's World Cup is Switzerland. That is because the Switzerland team are the only team in this year's World Cup who will be wearing topographical maps on their team shirts.

The American Noise Map

The U.S. Bureau of Transportation Statistics has released an interactive noise map of the USA. The map uses data from the Federal Aviation Administration and the Federal Highway Administration to show you how much noise you might be subjected to anywhere in the country.

The National Transportation Noise Map shows you how much aviation and highway noise noise you will endure at any address. In truth the map doesn't show you much more than you already know. Airports and busy roads are the source of serious noise pollution. Therefore if you live near a busy road you can expect to hear a lot of cars. If you live near an airport then you are going to hear even more noise pollution from those noisy planes.

The U.S. Bureau of Transportation Statistics say that the map provides "a basis for understanding what-if scenarios". This is where these transportation noise maps are most useful. They provide a valuable guide to the possible noise pollution that residents can expect from any planned roads and airports. The Bureau say that they will add additional transportation noise sources, such as rail and maritime, in future updates to the map.

Stop & Frisk in Chicago

Last week Maps Mania reviewed Stop and Frisk, a data visualization of New York's controversial stop and frisk policy. Of course The NYPD are not the only police force to have been criticized for practicing racial profiling in its practice of stopping and searching its citizens.

Stop and Frisk in Chicago is an interactive map which visualizes data from police contact cards between 2014 and 2016. The map shows the number of times people were stopped and searched in each Chicago city block. If you hover over a block on the map you can view the total number of stop & frisks carried out in that block. The map also allows you to view the number of stop and searches that were carried out in each block by police officers of different races (white, black, Hispanic).

The map was created by the Lucy Parsons Labs. You can explore the data further and download it here. The code for the interactive map is also available at GitHub.

UK Travel Time Maps

Esri has a created a series of isochrone maps for the BBC showing how far you can drive in the Friday evening rush hour in ten major UK cities. The Friday Night Rush includes ten maps showing travel distances in the UK's most populous cities on an average Friday evening.

Each map shows the average distance you can travel in an hour when leaving the centre of each city at 4pm, 7pm and 10pm on a Friday evening. The travel distances for each map were calculated using data from HERE's traffic speed predictions. These predictions are themselves based on up up to three years of historic data.

If you don't work in the exact geographical centre of one of the UK's ten most populaous cities then you could try TravelTime instead. TravelTime is a very handy tool for working out how far you can travel in different set times. It allows you to find areas you can reach by walking, cycling, driving or accessing by public transport in a defined amount of time.

If you share your location with TravelTime you can view an isochrone map showing you how far you can travel using different lengths of time. For example,  you can select to view all the places you could walk to within 15 minutes. TravelTime also allows you to search for venues and points of interest within your allocated travel time. So, for example, you can ask TravelTime to show you all the coffee shops within a 15 minute walk of your current location.

TravelTime also allows you to search from more than one location. So, for example, if you want to meet a friend for coffee you can enter both your locations and find the areas which you can both reach within a 15 minute walk.

TimeToAnywhere is another interactive map which shows you how far you can drive in the UK for different lengths of time. The map is very easy to use. Just click on the map to set your location and you can instantly view an isochrone layer showing the driving times from your selected location.

The stand out feature of TimeToAnywhere is its speed (drag the marker around the map to see how quickly the isochrone layer updates). However TimeToAnywhere also includes a number of other useful features. These include an option to view the isochrone layer for busy commuting times (when driving times are longer). The map also includes an option to view a route and travel time to a specific location, by dragging a destination marker onto the map.

Not everybody who commutes is traveling to work. Some commuters are traveling to schools. I think those people are called students.

If you are looking for a new school and don't want an over-long journey each way then you could use Parallel's Schools in England & Wales. This interactive map provides, walking, cycling and driving times for every school in England and Wales. Zoom in on any school and you can view isochrone layers showing the areas that you can walk, bike or drive to (or from) the school in six minute intervals.

96 Shootings a Day

The New York Times reports that on an average day 96 Americans die after being shot by firearms. Individual suicides and homicides don't get as much news coverage as mass shootings but they still contribute a significant proportion of the total number of gun killings in the United States.

In On an Average Day, 96 Americans Die By Firearms the NYT explores some of the data behind the daily toll of gun violence. This analysis uses data from the Gun Violence Archive to illustrate the incessant routine violence perpetuated by gun owners. This includes a timeline showing the number of people injured and killed by guns every day since the start of 2014.

Since 49 people were killed at the Pulse nightclub in 2016 there have been been at least 87 shootings in just a three mile area around the club. The NYT illustrates this point with a clever interactive map. As you scroll through the article an expanding circle shows an ever increasing area around the Pulse nightclub in Florida. As the circle expands more and more shootings are revealed on the map of Orlando. By the time you get to a circle showing 14 miles around the club the number of shootings has risen to 383.

Maps that Changed the World

The Library of Congress has thousands of world maps in its collection. If you browse the collection in chronological order you can explore the history of cartography and, at the same time, gain an insight into how the world has been perceived throughout history. The Library of Congress' World Maps is a small presentation of some of the library's most important world maps.

I'd like to take all the credit for selecting the world maps in this short presentation. But I can't. These maps all come from a story map created by the Library of Congress itself. Maps That Changed Our World is an interesting interactive tour of some of the most important maps owned by the Library of Congress. Starting with the world atlas from Ptolemy's Geography published in 150 AD this story map takes a chronological tour of world maps through history.

The world maps chosen for this story map each represent an interesting shift in how the world was visualized. The maps start with Ptolomy's Geography and progress through important maps from the Middle Ages, the 17th and 18th centuries, and right up to our modern digital maps.

The Library of Congress' story map includes information about each of the maps which helps to place them within their historical context. However all the featured maps presented in Maps That Changed Our World are presented as still images. This is why I put together my own short presentation of the Library of Congress' World Maps. My map presentation allows you to explore all but one of the maps as interactive maps. So you can explore the maps in detail in my presentation and learn more about their creation using the library's story map.

The only map missing in my presentation is the world atlas from Ptolemy's Geography. This is because I couldn't find the individual iiif manifest for the map on the Library of Congress website.

Safe Cycling in Berlin

A new interactive map from Tagesspiegel provides a complete audit of the safety of Berlin's roads for the city's cyclists. Berlin is Planning New Bike Paths shows where new bike paths are being built in Berlin and also assesses all existing roads based on how safe they are for cycling.

Roads on the interactive map are colored to show how safe they are for bikes. This score is based on the length of the road and how much of the road has measures to support cyclists. If you click on a road on the map you can view details about how safe it is for cyclists. These details include the length of any dedicated cycle lane, the length of any bike paths and the length of any protective barriers on the road.

The red roads on the map have the least measures to support safe cycling. These roads tend not to have separated bike lanes or any protective barriers.  The yellow lines on the map are the new bike paths Berlin is building to support safer cycling in the city.
