I do not load the same combination of KML layers. In fact, it's dependent on the user's input in a way.
I am able to create a single KML file which contains Polygon definitions and coordinates from merging all 15+ of the single KML files. However, my issue with this is that I also have Markers placed in the center of each Polygon after it renders. Specifically, I'll have a listener on the "metadata_changed" event for each of the 15+ single KmlLayers. Then once that fires, I'll create a Marker setting its position to "this.getDefaultViewport().getCenter()" which refers to the layer. I pretty much only need the center point from that layer now that I can generate a KML file on the fly of all the merged KMLs that the user selects. I've tried not calling the layer.setMap(myMap) function, but this means that the "metadata_changed" event never fires. So then I decided to remove the layer after its "metadata_changed" event fires. This results in a LOT of requests to google since it has to request to create, then remove. This method seems to work, but it's very slow due to the large amount of requests. Cliffs: Can merge all KMLs into a single KML file, but now can't get center using layer.getDefaultViewport().getCenter() to set Marker's position for that "single" KML area.
