World Population Cube

Featured

World Population CubeLast November’s theme of the Super Science Saturday at the Oxford University Museum of Natural History was Planet Earth. As part of the activities I contributed a map cube which I created a few years ago.
Cubic globes are not a new idea. They put a nice twist to showing just a simple map, and more importantly, they allow for some activity which get the kids involved just as much as adults. A cube is much less work than creating a spheric version of Earth, and (as said by Carlos Furuti on his online cube globe collection) the cube is an ideal introduction to folding one’s own pseudoglobes.
At last November’s Super Science Saturday I displayed some of my work and offered a ‘Map Cube Activity’ where children (and adults) could cut, fold and glue their own globes. My version of a map cube does not display a normal world map, but a gridded population cartogram (hence the name ‘World Population Cube’). You can create your own cube by using the following template: Continue reading

Air Spaces: Where the Planes Fly

Cartographic Summit 2016The Future of Mapping was the theme of a Cartographic Summit jointly held by the International Cartographic Association (ICA) and Esri at Esri’s headquarters in Redlands (California). The aim of the event was to examine new directions in mapping in a time at which mapping is evolving at a rapid pace, enabling us to communicate in new ways, analyze important issues, and understand our world. Among the keynote speakers was graphics designer Nigel Holmes whom I had a chance to work with several years ago while making some contributions for Lonely Planet’s travel-infographics book How to land a jumbo jet. Meeting him in person at last reminded me to put online the last of the four cartograms that I made for the book.
The following map is a gridded cartogram visualisation of global flight tracks taken from the OpenFlights database. The map distorts the land area by the number of flights that pass a certain space which leads to these ‘ploughing patterns’ over some areas where are airplanes basically just passing by, such as in the western part of Australia where planes simply fly over on their way to the most populated southeast of the country. The colours in the map relate to the Worldmapper colour scheme (explained here).

Mapping the Anthropocene

Featured

The effects of humans on the global environment are perceived to be so significant by some scientists that they argue the onset of industrialisation (in the eighteenth century) has been a major driving force in environmental change on a par with the forces of nature. It is this rapid impact that has led some geologists to unofficially name (but not, as yet, officially recognise) this recent period of the earth’s history (from around 1760-onwards) as the Anthropocene (roughly translating as the era – or epoch – shaped considerably through the actions of humanity).

Planet Holiday: The World’s Major Tourist Destinations

How to Land a Jumbo JetTourist season is in full swing, especially in the wealthy parts of the Northern Hemisphere. Recent figures released by UNWTO World Tourism Barometer state that “international tourist arrivals reached 1,138 million in 2014, a 4.7% increase over the previous year.”
I mapped the grographical patterns of global tourism for the book ‘How to Land a Jumbo Jet‘ published by Lonely Planet. The following cartogram shows the countries of the world resized according to international tourist arrivals with the top 10 destinations also labelled (and listed on the bottom right corner), coloured in Worldmapper-style colours:
