Hi, this is an interesting topic and I created an example with german administrative borders.
Map: http://www.ralf-wessels.de/Beispiele/Bundesland_Bezirk_Kreise.html For this example I used data from GADM and simplified the shapes with Mapshaper (http://www.mapshaper.org/) because the original data took too long to load. To store the polygons I use a MySQL DB. I made this example map, to figure out, where is the border to handle large polygon data (a lot of polygons or very detailed polygons) wih the "normal" approach ( GPolygon overlay) with the focus on loading time. If the polygons are simple and you are not loading say more then 20-30 at the same time the loading time is acceptable. One problem with GPolygon overlays is: you can't display polygons with holes (and there are some in the dataset). Maybe I should try it with GPolygon.fromEncoded in the next example (to display holes) but I guess even better is to use image overlays (e.g. Polygonzo) for large Polygon data. I'm only wondering if I then have the same possibilities in my map (e.g. tooltips, mouseover- and clickeffects ....) as when I use the normal GPolygon overlay? greetings from berlin ralf --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Maps API" group.
