Do you have an idea for a new overlay? Read this!
First of all, the same general limitations and guidelines as for quests apply, see the quest guidelines. Additionally, data is only eligible for an overlay if:
- 🕸️ Contextual only: Overlays should only be used to display data that only makes sense in relation to neighbouring data, e.g. data in a network (such as cycleways, speed limits, ...) or data that depends (to a degree) how surrounding data is tagged (such as road smoothness, lit status, ...).
- 🔎 One aspect: Similar to the atomic quests guideline, only one aspect should be displayed and be editable to the user.
- ⭐ Not a quest: Usually eligible data should either be recorded and displayed in an overlay or as a quest.
The concept of overlays is very similar to the core concept of MapComplete which doesn't impose such restrictions.
