Map Interface

Hi guys,

I have been searching around for a geographical map interface to use, but I can't find one that suits what I need.

I need it to:
- Have a preloader
- Have + and - buttons to zoom in and out
- Allow a user to click and drag to navigate within the map, rather than press buttons.
- Be able to have clickable areas of the map for navigation to other sections of the web site.

An example of one I have seen is at:
http://www.sanctuarylakes.com.au/res_masterplan.html
, but this doesn't have the clickable links within it.

I hope someone can point me in the right direction.
