Experimenting With R – Point to Point Mapping With Great Circles

I’ve started doodling again… This time, around maps, looking for recipes that make life easier plotting lines to connect points on maps. The most attractive maps seem to use great circles to connect one point with another, these providing the shortest path between two points when you consider the Earth as a sphere. Here’s one

Aggregating spatial points by clusters

With ubiquitous collection devices (e.g. smartphones), having too much data may become an increasingly common problem for spatial analysts, even with increasingly powerful computers. This is ironic, because a few short decades ago, too little data was a primary constraint. This tutorial builds on the 'Attribute joins' section of the Creating maps in R tutorial to demonstrate how clusters can be...
