Cluster Explorer Demo

Cluster explorer is a piece of software I was working on, which blends machine learning and GIS to produce a cluster visualization on top of a virtual globe.
The virtual globe uses NasaWorldWind, a Java framework for 3D geo-visualization based on OpenGL, while the clustering algorithms use the ELKI Data mining framework for unsupervised learning.
The tool allows to cluster a bunch of points (for instance geolocated Tweets) using one of two algorithms (or both), and explore the contextual information provided by the geographic layers (e.g.: OSM, Bing).
