Edit wms layer

After clicking on the name of a wms layer, you can configure an existing wms layer. If you can not find the wms layer, use the search bar, or change organisations.

You can for example edit the description or share your wms layer with other organisations.

Tip

Advanced: Is your wms layer not visible in the Viewer? Check via the network tab (press F12) how Lizard requests the wms and if that wms url makes sense. You can always ask the service desk to help as well.
