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?

Thanks, Jeff

Which WMS server are you using? Having looked at the docs for Mapserver, I suspect it can cope with it, but I'm not expert. –  MerseyViking Jan 17 '12 at 11:06
    
More just a general question of the typical behavior. I didn't know if it was a client's responsibility to honor the min/max scale or if it is the server's job to only serve the imagery in the correct scale ranges. –  Jeff Storey Jan 17 '12 at 18:17
