[GIS] Number of zoom levels in WMS

ogcwmszoom

I want to calculate the numbers of zoom levels that has a WMS. I had a look to the WMS spec and I guess that it has to be related with bounding box area and image size.

There is no concept of zoom "levels" in the WMS specification, as there is for an XYZ/TMS. Rather, your WMS requests just use a bounding box which determines map scale.
