I'd agree with Anselm, the time controls of Google Earth are pretty
rudimentary, at least at this point. It's kind of akin to using an old
cassette player... you can play time forward, and stop it, and fast
forward and rewind by dragging the control, but that's about it.
I would like to see Google Earth treat navigation in time similar to how
they treat navigation in space... give users the ability to easily zoom
in and zoom out (in time), play it slowly forward and backward, and go
beyond the minimum and maximum temporal boundaries of whatever
time-stamped data you happen to have loaded. And even more importantly,
allow some mechanism for GE to send the time interval information to an
external server (similar to how you can send spatial information to an
external server using the NetworkLink and ViewFormat tags) so that
server can respond with data for the requested time period. This could
allow GE to browse large historical time series of user provided content
(served from a external db), that would overwhelm GE in its present form
(which I seem to do on a regular basis).
Don't get me wrong, I like GE, and regularly use it to visualize
temporal data. Its vary useful even with its current (rudimentary)
treatment of time.
