Time slider to fast

[Tijs de Kler]

Hey,

I am currently involved in research on bird migration patterns.
Each half hour, we get the measured bird tracks in a certain area, and
we have put these tracks in a KML file with the correct timeSpans
attached.

The thing we would like to look at is the bird tracks over a period of
for example 5 days, resulting in a dataset with 240 timesteps.

The problem is that the visualization goes to fast. Even with the
animation speed setting to the lowest possible setting, the animation
is over inside 20 seconds, resulting in less than 1/10th second per
frame and as far as i can tell even skipping frames, though im not
sure about that.

What we would like to have is a setting where we can specify the
amount of time each time step takes, and so make the bird patterns
better visible.
Does anyone know if this is possible and how it can be done?

Thanks for your help,
Tijs

Hi Tijs,

I have Google Earth 4.2 on one PC, and 4.3 on another. When I play one
of my KML files (several events over a one day period), it takes about
20 seconds to play though the day using GE 4.2, and 65 seconds for GE
4.3. Both are set at the slowest possible setting. So... I'm guessing
you are using GE 4.2. Even at 65 seconds, I wish I could slow it down
further - perhaps 2 or 3 minutes to play the entire file.

I don't know of any way to slow it down further. Gurus?

Yes, you can slow it down. Click on the options button next to the
slider and it'll be obvious.

There is not a way, in KML, to set this.

We found the option, but it is not really sufficient in slowdown.
What we want is to get it to go so slow that you can actually see the
individual time steps, and if you see something interesting, pause and
zoom in.
At the moment this is impossible, because even on the slowest setting
the steps shoot by too fast to really see anything.

regards,
Tijs


What would be really nic

Hi Tijs,

One thing people do is use TimeSpans instead of TimeStamps to
represent small chunks of time, so that they show up longer.

You might like to look at my StarTraX project which will display the
tracks in real time - may be too slow, but you can step from point to
point. It only works with a single track, but might be of interest.
