Layer hierarchy...

[Bernd Welter]

One of my partners asked:

We want to combine the satellite images with other layers. When the opacity of the satellite layer is set to 100% we can no longer see other contributing layers. How can we get rid of that? Does it make sense to change the sequence of adding the layers? How can we ensure to put other layers on top?

Changing the sequence of "adding layers" might solve the problem for the current set of layers, but I recommend to use the following approach to avoid too many dependencies:

Use the layer's priority attribute !

Here's some additional info

• About the priority attribute
• About the layer concept in general

No matter when you add which layer in the application: you can control the z-hierarchy via this priority attribute.
