Insert our properties in the source layer tree.

Also remove empty layers.

Parameters:

• layers – List of source layers

• revert – Revert the order of layers and sub-layers.

gws.gis.source.filter_layers(layers: list[gws.SourceLayer], slf: LayerFilter = None, is_group: bool = None, is_image: bool = None, is_queryable: bool = None, is_visible: bool = None) → list[gws.SourceLayer]

Filter source layers by the given layer filter.

gws.gis.source.combined_crs_list(layers: list[gws.SourceLayer]) → list[gws.Crs]
