Add, remove, update many kinds of overlay objects (markers, labels, polylines,
polygons, curves and circles, 2D and 3D kml/rss xml sources, Bing Collections, arrows) simply.
And do not worry if you have many overlays, TGAgisBingMap can optimize display for performance or quality.
And use an extensive amount of properties / events to manage your map, and overlay objects.
All overlays allow submitting multiple changes at once with BeginUpdate and EndUpdate methods.
They all can be set to be visible at certain zoom ranges also.
Overlays can also be grouped under a Layer, so that showing / hiding them at once becomes possible.
