DrillDown
renderer allows
you to display more and more objects as you zoom in the view. The
objects are dispatched to different manager layers with visibility
filters, which are configured according to the object property DrillDownZoom
.
All the objects with the same drill-down zoom are placed in a manager
layer that is visible only when the view’s zoom level is greater
than the drill-down zoom. DrillDown
