I decide to start writing the posts in English from now on. I got complaints from friends that would like to understand the texts as well (thanks for that! ☺).
It has been for a while now, that I am passionately interested in understanding the process of investigating large amounts of data. Specially in how to present and design data visualizations.
I’m taking different approaches and making some experiments with the available tools.
Last week, it was about using Processing to project a data-set onto a map. I finished an online class at Skillshare (with Nicholas Felton), and got really nice results with the Meteor strikes data-set. After that, I tried the online mapping platform Mapbox to see if it would be easier and better. It turned out to be quick and interactive, but limited when compared to Processing. For example, when you need the map for printing.
Today it’s about another online mapping platform: CartoDB.
I’ve created a map at the CartoDB site, based on a data-set my sister Sarah is working on and kindly shared with me for this experiment.
You can check the interactive version online here.
The data-set is about a marsupial called Chironectes (water opossum), that lives in the waters of Central and South America. The map shows the exact locations where the animal was seen or found. In the interactive version more details appear by “mouse hover”. The colors show the different sub-species.
I found working with the cartoDB much easier and clear, compared to Mapbox. It also gives the possibility of exporting the layers as SVG, a feature that I’ll be exploring next.
I also made a map for Sarah showing the locations and quantities of the cataloged Chironectes.
If you are interested in maps and data visualization, you should definitely have a look at the CartoDB website and explore some of the last maps created. A post about exporting SVG from CartoDB will be following soon!
