!! `<$geobaselayer>` widget
The `<$geobaselayer>` widget is used inside the `<$geomap>` widget to define the base layers to display on the map.
The following attributes are supported:
|!Attribute |!Description |
|''title'' |Optional title of a tiddler that defines the base layer through the fields ''caption'', ''tiles-url'', ''max-zoom'' and ''text'' (the text field defines the attribution string for the base layer) |
|''name'' |Optional name for the base layer |
|''tiles-url'' |Optional templated tile server URL for the base layer |
|''max-zoom'' |Optional maximum zoom level for the base layer |
|''attribution'' |Optional attribution text for the base layer |
The base layer will only work if all four of the required items ''name'', ''tiles-url'', ''max-zoom'' and ''attribution'' must be provided, either through the base layer tiddler specified in the title attribute, or explicitly via their own attributes.
See https://leaflet-extras.github.io/leaflet-providers/preview/ for a collection of compatible base layers.
