Having a a client-side performance problem due to a large number of polygons being brought down to a Google Map. Sometimes the GZipped response is around 2MB worth of GeoJSON. I'm hoping that I can partially solve the problem by simplifying the polygons using ST_Simplify. The problem I'm running into is that the polygons are all contiguous and after simplification they are not connecting with each other. (See attached image) Anyone know how I can simplify the polygons and keep them all "fitting together"? -- Steve Horn
