Map Comment
Map comments are objects used by editors to annotate the Waze map. They are used as notes, explanations, warnings or reminders for editors and can be made by any editor anywhere, regardless of editable area. They appear, if the Map comment layer is enabled, as white points and polygons in the Waze Map Editor.
