Subject: [postgis-users] Simplifying Polygons
Hello!
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"?
