@AnaBelgun I've looked at this. The trouble so far is the legends (see screen grab below)

Basically there are 4 layers which automatically turn on and off as you zoom closer. At the moment we show all 4 legends at once.

We could add the 4 layers as seperate lines items to the catalog but then the layer is only visible for a certain zoom range which is also annoying...

No easy answer sorry

ok, let's leave for now and I'll give this feedback to Steve from GA.

Feedback: Our services show the legends for each layers which has, this helps with online requests for layers and printing. However, if you make a basic mapserver legend request (see below) you could translate that json into a single image or html response. I don't think there is an easy answer, it was not designed to combine legend images (I think).

I think I'll just hide the legend for the timebeing. In mobx we can perhaps work on scale-dependent legend rendering
