Interactive Office Floor Plan Map
Mark Laudon of Street View Gallery has used the Google Maps API to create an interactive office floor plan, complete with employee profiles. The example map is a demonstration of how Google Maps can be used with floor plans and a database of employees' locations.
The map overlays floor plans of an office directly on the building's satellite view in Google Maps. The Interactive Office Floor Plan has the ability to map the positions of employees on the floor plan. The map includes a search box so you can search for employees or you can select an employee from a drop down menu and find the location of their office on the floor plan.
The map even includes an ESRI ArcGIS layer and it is possible to switch between Google Maps satellite view and ArcGIS.
