One Hundred Years of Earthquakes

Category: Google Maps | Jun 29, 2015

Kenneth Davis has been busy Visualizing One Hundred Years of Earthquakes. He has created three different maps from the data to show earthquake activity through time, a heat-map of all quakes over the last one hundred years and a depth map of the quake data.

The animated Torque powered map shows a marked increase in earthquakes after the 1950’s. This isn’t a result of more earthquakes but due

Mapping Population Trends in Europe

Category: Google Maps | Jun 29, 2015

Last week the German Federal Institute for Research on Building, Urban Affairs, and Spatial Development released a map showing how population has changed in Europe between 2001 and 2011. The BBSR Map of European Population Change shows where populations have increased and decreased throughout Europe.

The Berliner Morgenpost has now created an interactive version of the map using the same data.

The Best European Bird Maps

Category: Google Maps | Jun 29, 2015

Belgium’s birds are a lot like New York cabs.

Actually Belgium’s birds are nothing like New York cabs – but they do have one thing in common – people can’t stop mapping them. In America Chris Wong’s taxi data has proved irresistible to mappers, European mappers however apparently can’t get enough of LiveWatch INBO’s Belgium bird data.

At the beginning of the month I posted a round-up of the Top

24 Hours of Train Traffic in 60 Seconds

Category: Google Maps | Jun 28, 2015

There has been a long tradition of using transit network timetables to create real-time transit map simulations. Vasile Coțovanu’s Swiss Railways Network
was probably the very first nationwide transit map which simulated train movements in real-time based on the network timetable.

Recently a new approach to mapping GTFS transit timetables has become popular. This new approach uses CartoDB’s

Mapping the Sale of Liquor

Category: Google Maps | Jun 27, 2015

The sale of liquor in Vermont is controlled by the state’s Department of Liquor Control. There is obviously some debate as to whether the sale of liquor in Vermont should be privatized. However the fact that the industry is controlled by the state does mean that all the data surrounding the sale of liquor in Vermont is freely available.

Vermont’s Seven Days has taken this data and created a

Paint the Whole World with a Rainbow

Category: Google Maps | Jun 26, 2015

Could there be a better way to celebrate Pride than to paint the whole world with a rainbow?

This weekend people across the globe will be celebrating Gay Pride. The Pride rainbow colored flag will probably feature quite prominently in many of the Gay Pride events being held over the next few days.

Mapbox has started the party today with this Love Wins rainbow colored map. On this map the

Mapping the Transatlantic Slave Ships

Category: Google Maps | Jun 26, 2015

Earlier this year Professor Adam Rothman  and Matt Burdumy of Georgetown University created a series of heat-maps using data from the Transatlantic Slave Trade Database to visualize 35,000 slaving voyages (from 1500 to 1870).

Their visualization of the Transatlantic Slave Trade Database consists of three animated heat-maps showing the cumulative frequency of slave ship points of departure,

The Map Projection Wizard

Category: Google Maps | Jun 26, 2015

If you want a little help deciding which map projection you should use for your current map project then you should use the Projection Wizard.

This map projection guide allows you to select the extent of the map view you are working with by outlining the area on a Leaflet map. Once you’ve highlighted your map bounds you can choose a distortion property (Equal-area, Conformal, Equidistant or

Mapping 40 Years of Global Terrorism

Two new interactive maps of global terrorism casualties (1970-2013) provides insight into terrorism hot-spots around the world and the changing geography of terrorism over those 44 years.

The Global Terrorism Casualties map visualizes terrorism casualties around the world as a dot map. The concentration of dots in Northern Ireland, Pakistan, Afghanistan, Algeria, El Salvador and in other
