change frame sequence for loops of mixed data type

[joleenf]

Hi,

I was wondering if it is possible to change the frame sequence in a loop that has both satellite data and point data. I have had a few people comment that the satellite image changes before the aircrafts observations in the attached animated gif (Note: image changes to 8:02 Z long before the aircraft ob reaches 8:02 Z). I have tried changing the interval, but that increases the number of frames excessively and did not solve the problem.

Also, I did not find a way to maintain the box color for the flight track (blue in the McIDAS window). It washes to white in the animated gif. I tried reducing the number of color levels used for the satellite image to 246, but this did not help.

Thanks,
Joleen

Hi Joleen,

This effect is the result of much higher time res for the track
point than the image. The image displayed has the closest
time to the track point time, the image changes about half
way between the two image times. Couple of points, if
it switched at 8:02 then the old image is displayed longer,
now the difference is split. The image time is really only
a nominal time anyway, so I'm not sure if we can say much
about features in the image to the nearest minute? Maybe
you know the answer to that. I'll look into what we might
be able to do in the Animation Control.

Hi Tom,

Yes, you are correct, the image time is nominal. The point track data is much higher resolution than the satellite data. There have been a few viewers who have asked for the image time to change closer to the point data time so that increasing the amount of time that any one satellite image is shown would not bother them, what bothers the viewer is that the nominal satellite image time changes so far in advance of the point data.
