Cartographic tools for data journalists

Last Saturday I attended the Jornadas de Herramientas Cartográficas organized by Geoinquietos and the Periodismo de Datos group in Medialab-Prado. Several professionals, cartographers and journalists mostly, gave an insight of their work and the tools they most commonly use. The event was focused on election maps (#electionmaps) and you can find a GitHub repository with all the slides and scripts which were displayed during the workshop.

Thanks to Xosé Manuel Vilán and Jesús García we learnt how to make hex maps with Quantum GIS, Graeme Herbert showed us how to make prediction models applying the not-well-called D’Hont Law and a couple of epidemiologists from the Instituto de Salud Carlos III, Rebeca Ramis and Diana Gómez, explained to us how to analyze spatial data with Geoda software. Carlos Gil and Beatriz Martinez also introduced us into mapping with R. A very interesting talk was given by Jorge Sanz from CartoDB.  He showed us how to solve the eternal geographical problem of the Spanish geography: putting the Canary Islands on the map. And he did it with just a few lines of SQL:

You can observe the result thanks to the following map. Before and after running the code.

Daniele Grasso and Adrián Blanco talked about their work at El Confidencial and gave us a quickly and easy tutorial in making maps with Leaflet. It is amazing how easy is to make a map with a few lines of Javascript. The following one, for instance, I made it in a few minutes. It depicts the Game of Thrones filming locations in Spain from last season.

I recommend you to have a look at my Resources page where you can download the majority of the software used in this post. And then of course… try to make a map!
