How many planes should be displayed?
Refresh Interval?
Click on a plane to see positional information about it!
Note: Changes to this value will only limit new features that are added (i.e., if there are 40 features,
and you drop it to 20, then it won't add any new features until the number displayed is less than 20.
It will not remove existing features. Features are added at a rate of 1 per interval (1 second).
Other Notes: In this demo, all feature placement, position recalculation, etc. is performed in the
browser using JavaScript. This includes determining if a feature is "off screen" or not
(for removal). Normally, this would be provided using a data feed (which features to remove,
and which to re-position). Increasing the refresh interval (> 1s) will increase the total number of
supported features.
This same exercise can be performed using an image overlay generated on a server (and refreshing the image). Such a display would
be faster, since the browser need not perform any feature/layer generation. Hybrid models are also supported.
Although not done in this example, we can also scale the size of the plane based on the zoom level (so as you zoom in/out, planes get larger/smaller)
