Im using the google earth v1 javascript API to update hundreds of objects moving around in “real-time”. I keep track of new, modified, and deleted entities to minimize looping in my javascript while updating placemarks, but still the biggest bottleneck is making the calls to the google earth api. Has anyone else tackled this problem? I’ve read a bit about dynamically streaming from a KML file on a server, but I need access to the placemark object updates in my javascript code.
To put a bow on this question. Using dynamic KML files is one way to do this if you dont need to do anything complicated with the data other than display it to the user. Because I need to do work on the data inside the webclient, I ended up using json to transfer the data and then using google.earth.executeBatch to execute my google earth api calls in the most efficient manner.
