A preview of the code I’m developing – I’m calling it Cartagen. It’s a web-based vector framework for dynamic cartography. A Ruby server receives map data from OpenStreetMap and from participants’ cell phones in real-time. Data is plotted in native HTML 5 with the canvas element, and styled with a new stylesheet format, GSS: Geographic Stylesheets. I’ll be demoing a more complete system during the MIT Media Lab’s Sponsor Week.
