Categorical spatial interpolation with R
How I used the kknn and ggplot2 packages together with some parallel computation to spatially interpolate several hundred thousand points.

In this blog post, I explain step by step how I (eventually) achieved a nice thematic map with pure ggplot2 – from a very basic, useless, ugly, default map to the publication-ready and (in my opinion) highly aesthetic choropleth.
Truth and Beauty in Georeferenced Social Media
As georeferenced data from social media, be it in the form of Tweets, Foursquare Check-Ins, Instragram photos, Flickr pictures, etc., are increasingly available, so do (geospatial) analyses and visualizations done with them become more and more popular.
