Recent news about sabre-rattling in the South China Sea prompted me to look up the actual EEZ boundaries, which I had downloaded for a project mentioned earlier - this issue also discussed re: the Arctic here and here - the area in dispute jumps out of the map just posted on arcgis.com. Its immensity is very apparent by using the Measure tool: roughly three quarter million square kilometres or a quarter million square miles! It was also a good excuse to use Esri's new and beautiful ocean map. The arcgis.com entry also details the selection and layering criteria used to post the map simply yet effectively.
PS: if you don't have ArcGIS to read this map, then get your home copy for $100 here.
