Mercator revisited

The 5th of March 2012 marks the 500th birthday of Gerardus Mercator, the creator of the world map that profoundly changed our views of the world. He was not the only one who worked on a conformal map projection in the 16th century, which was still an age of exploration and discovery. But he was the first to do the maths right and complete a world map that allowed ships to navigate around the planet by its ability to represent lines of constant course. That makes the Mercator projection a milestone in the history of cartography and remains one of the central map projections up to the present day. Continue reading

AAG Annual Meeting 2012New York is the host city to this year’s AAG Annual Meeting. For my plenary presentation at the Population Specialty Group session I therefore decided to add a little bit of a local touch to the talk by including a new map of New York City in the slides. Continue reading

A population-centric map projection

Here is some material from a presentation at this year’s  AAG Annual Conference in Washington DC. The presentation People powered maps: A population-centric map projection was given in the session on Topics in GIS, Remote Sensing, and Spatial Analysis and showed some new works on our grid-based cartograms (as presented at GISRUK 2009 and ESRI UC 2009).
The following animation shows the transformation of a topographic map of the United States, ending in a grid-based population cartogram (and then reversing). Please notice that loading the animation takes a while on slower internet connections:
