Dynamic Polygon in KML

[Nilanjan Dasgupta]

I am trying to write a KML document where a user-defined polygon will be changing its location in time. I have a simple polygon (a rectangle) in lat/lon that is currently displayed in KML. I want to add the functionality to show the polygon changing its location as one uses a time slider.

You can't readily have a polygon that moves (it is sort of possible with Network Links, but is not easy) 

To animate with the timeslider, you need to create lots of polygones, that each have their own time specification. So as the user drags the timeslider, the various markers switch in/out of view.
