function hook_openlayers_layers_info in Openlayers 6

OpenLayers Layers Info

This hook tells OpenLayers about the available layers that can be used by name in maps. Layers can still be defined manually, but this allows for easy calling of layers, and these will show up in the Preset UI.

Return value

Return a nested associative array with the top level being a unique string identifier, and the nested array containing the following key/pairs:

• "name": Translated name of the layer. This will show up in the Preset UI.
• "description": Translates description.
• "file": The Drupal path for where the callback is stored
• "callback": The name of the PHP function that will be called when the layer is rendered
• "projection": An array of projections that the layer is compatible with. Leave empty if compatible with all.
• "baselayer": Boolean whether the layer is a base layer or not.
