Where is the News?

Forbes has carried out an analysis of the Television News Archive to create a series of maps showing which areas of the world have featured in the news programs of some of the major television networks. The Forbes article Mapping a Decade of Television News includes maps showing the coverage around the world of the BBC, CNN, Fox News and MSNBC.

Unfortunately the article only has static maps which does make them a little difficult to read and compare. However these maps are PNG images which means you can click on them and view them in full-screen mode. Personally I can't make out a huge difference in the global coverage of the different television news channels. The obvious major difference is that the BBC has much more UK news than the American stations and the American news channels cover American news more than the BBC.

Overall there seems to be a lot of agreement about where the major news stories are around the world. At the end of the article there are two videos of animated maps showing where the featured news channels have focused their attention around the world over time. These animated maps show the focus of the news channels traveling around the world responding to global events and then moving elsewhere as the world's attention moves on.

The World's Population Pyramids

Earlier this year The Pudding created an impressive interactive map which visualized the world's population in 3D. The Pudding's Human Terrain interactive map shows population density across the globe using 3D population pyramids. The taller a pyramid block on The Pudding map then the more people live there.

The Pudding has now used its own map to explore in more detail the pattern of population density around the world. In Population Mountains The Pudding examines how unevenly the world is populated and how population density can take different forms in different parts of the world.

For example The Pudding compares the pyramid population maps of some European cities to Kinshasa, DRC. In Kinshasa poor transportation infrastructure has led to a densely populated city center, whereas European cities tend to have less densely populated centers and more densely populated suburbs. Because of poor transportation in Kinshasa the population pyramids in the city center fall sharply away, while in European cities there tends to be a more gradual slope from the center away into the suburbs.

If you don't like The Pudding's 3D visualization of the world's population then you might prefer the SEDAC Population Estimator (GPWv4). This interactive map uses NASA's Earth Observing System Data and Information System (EOSDIS) data to show where the world's population lives. The SEDAC Population Estimator map includes a tool to draw an area on the map to view an estimate of the population that live there.

How Religious is Europe?

Romania has the most religious population in Europe. 55% of Romanians are 'highly religious' according to a recent Pew Research Center survey. The least religious population in Europe lives in Estonia, where only 7% are highly religious.

In How Religious is Your Country? Pew Research discovered that in general Central and Eastern Europeans are more religious than Western Europeans. In Central Europe the southern mainly Roman Catholic countries of Italy, Spain and Portugal are more religious than most other Central European countries. Although Ireland, another mainly Roman Catholic country, also scores highly when compared to other Central European countries.

The Pew assessment of its religious survey of European countries is accompanied by a choropleth map which shows the level of religious belief in 34 European countries. You can mouse-over individual countries on the map to see what percentage of the country's population are highly religious. In its survey Pew looked at four measures of religious observance. These were: attending religious services at least monthly, praying at least daily, believing in God with absolute certainty and saying that religion is very important to them. Those people who scored highly on at least two of these measures have been deemed to be 'highly religious'.

The Queensland Bushfires from Space

The United States is not the only country in the world to have suffered from record levels of wildfires this year. Last month hundreds of bushfires ravaged the Australian state of Queensland. The intensity and scale of the fires were worse than any fires previously experienced in the state.

ABC News has used satellite imagery to help show the massive areas of the state that have been affected by the fires. In From space, the ferocity of Queenland's bushfires is revealed satellite imagery from the European Space Agency’s Sentinel 2 satellite has been used to reveal the areas affected by the fires.

As you scroll through ABC's presentation the satellite imagery shows around 45,000 hectares of land which were scorched by the fires. The imagery also reveals the homes which were threatened by the fires. Most worryingly the satellite imagery shows how the bushfires penetrated the region's rainforests, an extraordinary development which has alarmed fire scientists. Rainforests usually do not burn so this development shows how extreme global warming is creating environmental conditions outside of our previous experience.

The Most Sung About Locations

New York is the most sung about city in the world. Closely followed by London, LA, Paris and Miami. Celebrity Cruises has released an interactive map which reveals the most sung about locations across the globe.

To make Music Mapped Celebrity Cruises scanned the lyrics of over 200,000 songs. These songs all appeared in the top 40 of the US Billboard Hot 100 and UK Official Singles chart since 1960. Celebrity Cruises noted every mention of a city, town, neighborhood or state which appeared in these songs. This extensive research resulted in a final data set of 2,000 songs by 896 artists with 420 different places mentioned around the world.

The size of the markers on Music Mapped reflects the number of songs which have been sung about that location. If you click on a location's marker you can discover all the songs since 1960 which have mentioned the selected place. You can even click through to listen to each of those songs on Spotify.

Dangerous Biking in LA

An interactive map by the LAist reveals that there is almost no section of road in Los Angeles where a cyclist hasn't been injured. The L.A.-Long Beach Bike Crashes interactive map shows the location of every collision within Los Angeles and Long Beach involving bicycles from 2010-2015.

The LAist argues that with its wide, flat roads and sunny weather LA should be a wonderful place to cycle. However Bicycling Magazine has named Los Angeles America's worst city for bikes. Looking at the LAist interactive map it isn't hard to see why. The map shows that from 2010-2015 70 bicyclists were killed and 13,606 were injured while cycling on the city's roads.

The LAist point out that the city's Three Feet for Safety Act is very rarely enforced. This law requires drivers to leave at least a three foot gap when passing a cyclist. However the police have issued only 13 citations in the four years since the act became law. The LAist's conclusion is that the city needs to invest in cycling infrastructure. The best way to ensure the safety of cyclists is to create separated bike lanes so that car drivers actually are incapable of driving within three feet of a cyclist.

Global Wind & Rain

The animated interactive weather map Ventusky now has a new radar layer, which can show the levels of rainfall around the world. The Ventusky weather map offers highly accurate data about weather conditions around the world. It now offers even more accurate precipitation data across the globe.

Ventusky has been working on its new radar layer for over a year. The layer uses sources from all around the world. It includes data from nearly 200 weather radars in North America, covering the USA and Canada. It also includes data from 100 weather radars from Europe and a few dozen more radars around the globe.

On the map the radar layer shows the intensity of precipitation. This intensity of precipitation is displayed using colors ranging from blue for light precipitation to red for very heavy precipitation. Using the timeline controls, running along the bottom of the map, you can animate the radar layer to observe precipitation moving and developing over time.

The Most Densely Populated Areas in Europe

The most densely populated square kilometer in Europe is in the center of Barcelona. This square kilometer in the Sants-Montjuïc district of Barcelona is home to 53,119 people.

Dan Cookson's Hyper Density in EU maps every square kilometer in Europe with a population of over 10,000 people. Kilometer squares with a population over 10,000 are colored on the map to show their population density. Each of the colored square also has a label which shows the exact population living there according to the European Commission.

If you want to know which areas are the most densely populated in each European country then you can refer to Alasdair Rae's article on The Most Densely Populated Square Kilometre in 39 European Countries. In this post Alasdair shows a satellite view of the the most densely populated kilometer square in each European country. Each satellite image also includes a small inset map showing you where that most densely populated area is

If you are interested in areas which aren't so densely populated then you should also check out Dan's previous European population map. The EU Population 2011 by 1km Grid visualizes the number of people living in each square kilometer of the whole EU.

The Autocomplete Map of the USA

A few years ago autocomplete maps were very popular. Then they went away for a while. Now they are back!

Autocomplete maps show you the most searched for phrases on Google for different locations. For example if you type into Google 'why is Alaska ..' Google will list a number of auto-complete suggestions based on how most people use that question stem when searching on Google.

On Google most people use the 'why is Alaska ...' form of question to ask 'why is Alaska so cold'. Conversely the question stem 'why is Arizona ..' is most often used on Google to ask 'why is Arizona so hot'. You can find out the autocomplete suggestions for other states on The United State of Wonder interactive map.

The map shows the autocomplete suggestions for each US state for the question stems:

'Why is ... ?'
'When will ...?'
'Can ...?'

You can make your own global autocomplete maps using Map Channels' Autocomplete Maps. This tool, released in 2014, lets you enter your own question stems to create an interactive map showing the autocomplete suggestions for that question for locations around the world.

Russia's Attack on the World's Democracies

Russia seems intent on destabilizing democracies around the world. In just the last three years Russia has hacked into the servers of the Democratic Party in the USA, assassinated a person in the UK and, most recently, fired upon Ukrainian ships.

The Alliance for Securing Democracy has been tracking where and how Russia has been interfering in more than 40 countries around the world. You can explore these discoveries on the Authoritarian Interference Tracker. Click on an individual country on the Authoritarian Interference Tracker interactive map and you can view all the recorded incidents where Russia has interfered in that country's democratic process.

The Alliance for Securing Democracy categorizes Russia's interference in democracies into a number of different areas, including cyberattacks and political & social subversion. The map uses pie charts as markers to show the scale of these different categories of attacks by Russia on individual countries. The size of the pie charts are proportional to the scale of Russia's attacks on that country. If you select a country on the map you can read more about each individual incident, as listed below the map.

Building on Britain

Just under 6% of the UK is built on. More than half the land is farmland and around a third of all land is natural (heath, moorland etc). You can discover how much of your local area is built on using the BBC's new interactive map.

How Much of Your Area is Built On uses new data on UK land use, which was derived from analyzing satellite imagery. Enter your location into the BBC's interactive and you can find out how much of your local area is natural, farmland, green urban or built on. A map of your area shows which parts fall into each of these four categories of land use. You are also shown the total percentage of land in your area which is given over to each of the four categories and how that compares to the national average.

While 6% of the UK is built upon only 3.6% of America is dedicated to urban areas. You can find out about American land use in Bloomberg's Here's How America Uses its Land.

If you live outside of the UK or the USA then you can use the OSM Landuse Landcover map to get an idea of the different percentages of land use on your area. This map uses OpenStreetMap data to map land-use and show the percentage of different types of land-use around the globe.

The OSM Landuse Landcover map uses contrasting colors to show how areas have been tagged in OpenStreetMap for land-use and land-cover. If you zoom in on a location on the map you can see how different areas have been tagged for land use and land cover. A dynamic pie chart also provides an overview of the percentages of different types of land use in the current map view.

Obviously the data on the map is only as accurate and complete as the data in OpenStreetMap.

Discover Your 2018 Climate Twin

In the year 2080 London will experience weather which resembles the climate in Lima today. Frankfurt in Germany will be as hot as Malawi and living in Berlin will be like living in Lesotho in southern Africa.

You can find your 2080 climate twin using The Summer of 2080 Will Be This Warm interactive map. If you enter your location or click on your location on the map you can view the town or city in the world which has a climate now which is similar to the climate you can expect in your location in the year 2080. The map uses two different climate models. This allows you to find your climate twin for a global warming scenario of 4.2 degrees or 1.8 degrees.

When you search for your climate twin the map displays some details of the kind of weather experienced by your twin now (and which you can expect to experience in the year 2080). This includes the annual rainfall and the number of extreme hot and cold days.

The Flood Risk Map of England

The UK government's Long Term Flood Risk Map for England provides an overview of the chances that any location in the country will flood in any year. It shows you the chances that locations will flood in any given year from either surface water, groundwater or from rivers or the sea.

Locations are colored on the Flood Risk Map to indicate the chances that they will flood in a year. You can also click on a location on the map to view the local chances of flooding. An area that is shown as having a high risk of flooding has more than a 3.3% chance of flooding in any given year. A medium risk indicates a 1-3.3% chance of flooding and a low risk has 0.1-1% chance of flooding in any year.

The UK government can also provide a flood risk assessment for any individual property in the UK. If you enter an address into the Long Term Flood Risk Assessment you can find out the property's risk level from rivers or the sea, from surface water or the risk from groundwater flooding.

Comparing Countries by Size

Jason Davies has arranged the world's countries in order of land area. Russia, the largest country in the world, is the first country to appear on Jason's Countries by Area visualization. Luxembourg, the smallest country in the list, comes last.

The map of every country in this visualization is reproduced to scale. This means that the countries at the bottom of the visualization are very small when compared to Russia. This is presumably why Countries by Area stops at Luxembourg. Each of the countries are colored by continent. You can mouse-over the individual countries to view its size in square kilometers and its ranking in the list of countries by size.

You can make a direct comparison of the size of any two countries using the True size of interactive map. This map allows you to overlay any country in the world on top of the outline of any other country.

The True size of interactive map doesn't limit you to just two countries. Why not see how many of the smaller countries in Jason Davies list you can fit inside the outline of Russia?

Transmarine Dream

Come and explore the strange transmarine dream of Andy Woodruff's Beyond the Sea.

Back in 2016 in Beyond the Sea Andy Woodruff answered the question of what lies beyond the sea for locations around the world. He created a series of maps which showed where each continent could be seen from (if you ignore the curvature of the Earth and our imperfect eyesight) from every other continent. His maps show what lies directly across the ocean if you take into account the direction of the coastline at any given point.

Andy has now created an animated interactive map which visualizes all the locations which lie directly across the sea on one integrated map. Click on a country on the Interactive Beyond the Sea map and you can see colorful lines shoot out to show the worldwide locations that can be 'seen' if you look directly out from any point on the selected country's coastline.

The colors of the lines represent the different destination continents. The result is that if you click on a country you can watch a colorful 'firework display' of animated lines shooting out around the world. If you select the 'start fireworks' option you can actually watch the world's coastlines exploding in one global transmarine dream.

Flooding Models for the Netherlands

The University of Gronigen has released an interactive map which shows which areas of Friesland are vulnerable to storm water flooding. The Wolk Viewer map models how rain water flows through the streets after a heavy rain storm. It simulates both the flow paths of the rainwater and where standing water would accumulate. The map covers most of the Friesland area of the Netherlands.

The Wolk Viewer simulated flooding model is based on 60mm of precipitation an hour. The model is intended only for the analysis of flooding in built-up areas, which means the model only provides a reliable picture in urban areas. The map has two buttons which allow you to view the flow paths and standing water separately on the map or to view both layers together.

The flooding model shown on the map is based on a WOLK model originally developed by the Tauw engineering firm. A WOLK (CLOUDS) model is a simple flooding model which uses a digital elevation model to show how water moves from higher levels to lower levels, while filling up lower levels with water. It provides a reasonable guide to which areas are vulnerable to flooding during a heavy rain storm.

I Know Where You Were Last Summer

If you are German the Berliner Morgenpost knows what you did last summer. At least they have a rough idea about where you spent your vacation. The newspaper has used anonymized roaming data to find out where Germans like to travel.

In Mobile Data Reveals Where Germans Were Last Summer the Berliner Morgenpost has mapped the most popular destination for German holiday makers. The most popular country for German tourists as a whole is Italy, closely followed by Austria. The map also allows you to view the most popular destinations for residents of each of Germany's states.

Proximity seems to play a large part in the popularity of different countries in the different German states. For example in Brandenberg the most popular country to visit is Poland. In Schleswig-Holstein the most visited country was Denmark. In Niedersachsen the most popular country was the Netherlands. In Rheinland-Pfalz it was Luxembourg and in Saarland it was France.
