- Method Detail
  - startObserving
```
public void startObserving()
```
    Description copied from interface: GLMapItem2
    
    Start observing the subject. This method should register callback listeners on any properties of the subject that would affect its rendered representation.
    Invoking this method should generally refresh the state of the item.
    This method may not be invoked on the GL context thread.
    
    Specified by:
    
    startObserving in interface GLMapItem2
    
    Overrides:
    
    startObserving in class GLShape2
  - stopObserving
```
public void stopObserving()
```
    Description copied from class: AbstractGLMapItem2
    
    Stops observing the subject. This method should unwind any callback listeners registered via AbstractGLMapItem2.startObserving().

    Sync the NADIR clamp boolean with the current clamp to ground setting

    ortho - Map view
  - validateLabels
```
protected void validateLabels(GLMapView ortho)
```
  - getWidgetViewF
```
protected android.graphics.RectF getWidgetViewF()
```
    TODO: Currently a direct copy from GLMapItem - but will be reritten / removed when the final version is done. Retrieve the bounding RectF of the current state of the Map. This accounts for the OrthoMapView's focus, so DropDowns will be accounted for. NOTE- the RectF this returns is not a valid RectF since the origin coordinate is in the lower left (ll is 0,0). Therefore the RectF.contains(PointF) method will not work to determine if a point falls inside the bounds.
    
    Returns:
    
    The bounding RectF

    Returns:
  - _ensureVertBuffer
```
protected void _ensureVertBuffer()
```
  - _projectVerts
```
protected void _projectVerts(GLMapView ortho)

    TODO 4.4: Utilize the batch line string we already have instead of creating a duplicate vertex buffer (_verts2). Also should be noted this buffer is only used for hit testing and drawing vertices in editable mode.
