Introduction
To realize the dynamic playing of the data with the time axis, can create the spatio-temporal object information for the cache files and save it to the corresponding XML file. You can request to the server according to the time requirement. And then the server will automatically parse the XML file to return the corresponding cache file, so as to realize the dynamic data playing.
