Data had to be extensively edited to insert the necessary time fields to perform the animation which was a time-consuming task.
Population data had so many classification levels that changes were barely noticeable in the animated maps. For the 30 year period we were studying, reducing the classification levels would have shown no noticeable changes in the animation, while increasing the level helped but made creating a legend difficult.
Census tract boundaries do not conform exactly to the corporate limits of the city.
The layer to which a track is attached can have one time field or a start time field and an end time field. It is useful to have an end time field in cases where the time stamps are irregularly spaced so that there will always be a time stamp displayed as the animation is played.
Calculate Times finds the minimum and maximum values in the Start Time Field specified and populates these as the time values for the two keyframes you created.
The Start Time keyframe I created will now have a time value of January 1, 2000. The End Time keyframe will now have a value of January 1, 2030. You can see these values set on the Keyframes tab of the Animation Manager later.
9: Displaying Times of Time Slices on Display as Animation Plays
Ensure Show time in the display is checked and Show track name in the display is unchecked, since there is only one track in this animation.
Click the Keyframes tab and see that the time values have been populated for each keyframe in the Time column. Since my data was in ten year intervals I had to set the interval for each keyframe to 10 and the units to years.
Click the value for the interval of the Start Time keyframe and type “10”, then repeat this for the End Time keyframe.
Click the value for the units of the Start Time keyframe and click Years from the dropdown list. Repeat for the End Time keyframe.
Ensure that Restore state after preview is unchecked so the currently displayed time slice and symbology and positioin of the time text will be retained in the display after the Animation Manager is closed.
Navigate to the folder where you wish to store your animation file and enter a filename
If you have licensed Quicktime you can choose Quicktime (.mov) here, otherwise leave the Save as type as AVI (.avi). Choosing Quicktime without a license will result in a failure at the last step to export.
A Quicktime license is $29 and well worth the money – the videos made with it were 100x better than the .avi videos I first made. (Quicktime dialog at lower right.)
If you chose .avi you should see the Video Compression dialog to the left. Click OK to start the export and make sure your mouse pointer stays out of the main window.
If you chose .mov (Quicktime) you should see the box in the lower left. I recommend setting the Compression Type to Animation and leaving the other settings “as is.” Click OK to begin the export and make sure the mouse pointer stays out of the main window.
