Hey Victor,

I would kindly suggest to not remove objects mapped as areas instead of nodes without proper reason(, or alternatively discussing with the original mapper).

Objects which can be mapped more detailed, i.e. individual trees instead of tree line -not trees instead of forest if more than five or so, of course- or playground equipment/area as area instead of node should be left as nodes or areas respectively.

On the wiki it is currently explicitly okay to map as either node or area. Though, it is a guideline, not a rule.

If e.g. a street cabinet mapped as area does not render on your map of preference, please submit a request with the developers of the map style. Regardless, it can still easily be found using query applications. OSM is a database. not only a map.

For such cases, it is recommended to start a discussion with the community about mapping street cabinets as nodes and/or areas to reach a consensus. You can do so at

- https://community.openstreetmap.org/c/general/38/none
(the forum is usually faster to reply.)

Regards,

Daniel
