The MapView has two child views. The DOM element for a custom overlay actually needs to reside inside the markup generated by Google Maps, but the overlay is an Ember.View so the MapOverlayView is actually rendered as a sibling of the MapCanvas and then moved into the correct spot later.
Keep the overlay centered while panning
The default behavior for a custom overlay is to re-calculate the styles when the map is panned, but to build an overlay that stays centered on the map, the overlay should only be drawn once and then pan with the map.
Creating the overlay
Finally, once the overlay has been created and rendered, resolve a promise letting the application know the map is ready.
Final Thoughts
This project was extremely fun and was successful due to the collaboration between design and development. The Google Maps API gave us the creative freedom to completely customize the map, while Custom Overlays really pulled the experience together.
