Understanding distortions in maps

Here you have an article on Microsiervos with plenty of links to websites that help us to understand the distortions produced in maps – as we have seen in the classroom.

So, here you have the beginning (it’s in Spanish), and you can access the website and read as much as you want.

The coolest part is in this link: interactive comparison of many projections. Remember that the ones appearing here that we have mentioned in class are the Mercator and Gall-Peters – but check out the Miller cylindrical I too!

En Visualizing map distortion Mike Bostock y su equipo tienen una visualización interactiva del globo terráqueo en diversas proyecciones cartográficas. Basta elegir el tipo de proyección en el menú desplegable y moverse con el ratón para entender cómo se ve (izquierda) respecto a la realidad que se está viendo (derecha); el área delimitada por los puntos rojos es la misma.
