I'm interested in creating an interactive map on the web that will allow users to select layers of information that will populate on the map. I would also like the map to have zoom and pan capabilities. My confusion lies in trying to understand how the zoom function is programmed.

How many different images of the "oblique" map (the map image that does not change) would I need to create/host on a WMS to have a satellite view and a town view? 2? I want to make sure that I have the appropriate artwork before moving forward with programming.

Thank you,
