I absolutely agree with you … but again, geobrowser vs. analytical tool.
Humble opinion, GE has “just enough” in the way of time controls to be useful,
without overwhelming casual users who just want to see and understand things in
basic context. Same argument for integrated high-res mosaics, 3D models, etc.
{Though a TBOX equiv of BBOX would be very useful, for those of us supporting
geobrowsers, I have to admit – I’ll have to check if that’s on file with them
as an enhancement request}
Not saying they couldn’t add an “expert mode”, and ALSO provide more advanced
features … but I understand why they don’t, given their business model, and
that they’re by no means done “enhancing into” their core envelope.
p.s. one thing I REALLY would like – because of how much it confuses casual
users – is the ability to control whether the time slider is ON or not, from a
KML feed when it’s launched. Maybe it’s in networklinkcontrol in the next KML
ver …

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.

Actually, you can do what your suggesting with time tagging and the time
slider, though there are limitations (not sure on epochal coverage, for
example). Works great for vector stuff (e.g. little soldiers marching :-),
works for pixel overlays, but if it's actual imagery/photography, the delays of
loading the pixels slows it a bit.
Also, the new 5.0 client and server-side upgrades permit a "stack" of
imagery over a location, and being able to flick through them -- all served
natively from the GE server, not hosted separately as superoverlays.
I don't think there's ever been any realistic effort to focus on nor
"market" WW to that bottom "geobrowser" level of the pyramid, which is where
you're always going to see the biggest volume ("unwashed masses" thing) ...
like someone else said, Google is marketing aggressively. And now that KML is
the OGC-approved standard for "earth browsing applications", and Google is able
to ride that standards horse ... hmmm ...
Still checking on getting a copy of the geoweb pyramid out -- checking
gov't contract and corporate proprieties ... sorry for delay.

Funny, google earth seems rudimentary... why can't I rewind or unwind
the history of plate tectonic activity for example? Or watch the
armies of man battle back and forth across the landscape of our
history... It's pretty but still so young. Surprised it has such
market share when world wind is open source and has more of a
potential to become a truly collaborative deep-time visualization
platform.... anyway...

Not sure why you'd find that remarkable ... GE has far broader
exposure,
and the immediate semantic context was "general public", and
"outreach".
Doesn't mean they don't use WW as well, for what it's good for,
best
tool, etc.
Frankly, we're finding Google Earth used far more at this point
for
general visualization in the gov't communities, as well ... I
think with
the strength of KML as a "lingua franca" for data sharing for
the
masses, and the osmosis from public exposure, CNN and Foxnews
and home
usage, etc. -- not surprising that GE is pressing far into WW
usage
scenarios.
Somewhere I have this "geoweb pyramid" figure that shows the
broadest
usage at the bottom "geobrowser" layer, with the general public
using
GE/GMaps, and GIS savviness increasing as you go up the levels
(and the
populations shrink), with transition over to WW, ArcGIS
Explorer, ArcGIS
Desktop, Manifold GIS, ArcGIS Server, etc. as the air gets
thinner and
thinner.

sounds like a great job, but remarkable that they don't mention
their
own product WorldWind in this context and instead GE two times?!
