When serving RPF imagery (Raster Product Format) from a WMS, will the WMS handle which layer should be on top? For example, let's say I request layer X and layer Y in some bounding box, and layer X should be displayed at scale 1:10000 and layer Y should be displayed at scale 1:20000
I would expect that at scale 1:5000, layer X would show up since it is the higher resolution image (since it displays at the lower scale). Then I would expect at scale 1:15000, layer Y would show up. Is this typical WMS server behavior?
