You want to have the position-indicator to remain the same size (on screen), regardless of the zoom level of your map, right?
You want to indicate access routes, elevator position, etc. Right?
How are the new positions will be calculated? By moving the indicators, or by modifing the Zoom-pan of the map?
This is important to define the best approach.

Could you detail what it is you want to do with the overlays. I can think of two uses for them:

This is exactly what it's for. The SVG will be a map of the building, we use SVG because it scales so well on different window/monitor-sizes. So I'll just be using the overlay to draw some form of position-indicator, an arrow, or a dot something like that. And then, as new positions are calculated, probably move it and draw a trail from the previous position. I think an overlay is the best option for this.
But I need to read up on Java as a whole. So I'd like to see some source code. Preferrably something that is very similar to what I'm doing.
