RubyVor provides efficient computation of Voronoi diagrams and Delaunay triangulation for a set of Ruby points. It is intended to function as a complemenet to GeoRuby. These structures can be used to compute a nearest-neighbor graph for a set of points. This graph can in turn be used for proximity-based clustering of the input points.

The US Census can be hard to digest for mere mortals. Geographic data is hidden away in shapefiles, a format unsupported by the freely available mapping sites like Google Maps and OpenStreetMap. Map servers, like GeoServer and MapServer have support for shapefiles, but those solutions are often too much for smaller organizations to set up and maintain. Scensus is a project to bring simple mapping of US Census data to the rest of us. Scensus-utils is a set of ruby scripts and files necessary to transform the census data in use for the Scensus project. You do not need to install Scensus-utils to run Scensus, but they are provided to foster further collaboration on the techniques and tools used to map.
