Blogger Marc Belzunces has published an interactive map that uses Google Earth to show the location and concentration of the referendums on Catalan independence
The map of referendums on Catalan Independence can be consulted without restrictions. The blogger Marc Belzunces has created an interactive map using the application Google Earth. In this map you can see the distribution and concentration of referendums throughout the area. In addition, the application differentiates between municipalities where "Yes" votes have already won the majority, those that will hold referendums on December 13, and those that have not yet chosen a date for their referendum. The system automatically updates the map when new towns are listed on the Coordinator for the referendums on Independence page.
