** {{wiki:ProtectedMethod.gif|}} DrawCore(RectangleShape) **

This method draws the TrackInterativeOverlay.
== Remarks ==
This method draws the representation of the overlay based on the extent you provided. When implementing this abstract method, consider each feature and its column data values. You can use the full power of the GeoCanvas to do the drawing. If you need column data for a feature, be sure to override the GetRequiredColumnNamesCore and add the columns you need to the collection. In many of the styles, we add properties that allow the user to specify which field they need; then, in the GetRequiredColumnNamesCore, we read that property and add it to the collection.

== Return Value ==
  * Type:Void
