[MapProxy] How do I get these tile sets overlayed with transparency?

[Simon Seyock]

Hello,


Just FYI: The MapProxy documentation is available at 
https://mapproxy.github.io/mapproxy

The docs for the paletted configuration can be found here: 
https://mapproxy.github.io/mapproxy/latest/configuration.html#id10

You can always go to https://mapproxy.org and find the link to the 
documentation there.


Greetings Simon
