Another problem is that if you delete nodes the history of the data is not lost but preety much hard to find.

My advice to solve both problems, or at least what i try to do when editing in this kind of cases, is to put the old POI node as "entrance=main", and moving the rest of the data to the way.

Hi. There is a small problem that is (or can be) introduced when changing an element which is mapped as a node, and transform to an area, which is when some user in a mapping app ask to do to e.g. an hospital, when the POI is a node, that's ok, but when the POI is a area, you should also map entrances, so the app can find the right coordinates and route the user to the right place. In small places the problem is not much visible, but as the size of the POI gets bigger it becomes a problem.

Sure, thanks. Aerial imagery was misleading in this case. Please check street level imagery, as this is clearly a pedestrian way. Vehicles are allowed, but it is a pedestrian road (was pedestrianized a few years ago)

Is seems you are following iD suggestions blindly. Please don't follow them if you are not sure. The operator:type should be "public" according to the wiki description of the tag.

Hola. No son correctos esos datos. La estacion no tiene nombre. ANCAP es marca asi que va en la etiqueta "brand". y por supuesto, mucho menos "official_name".

Hi. What did you base this change on?

Hi. These are not streets, nor service ways.

Un adelantado a su epoca el Charly...

Hi.

A few of them were not fixes...

* operator:type=government for schools. Each school has its own direction, so "public".

* name=ANCAP in fuel station, brand is not name.

Please do not blindly follow iD suggestions, as some of them are not good ones.

Hola.

En addr:postcode va el CPA (el nuevo de 8 caracteres). En este caso seria E3200AMI, que es el que indica hasta la manzana.

El codigo postal viejo 3200 se tendria que usar solo para etiquetar un area grande, con la etiqueta "postal_code"

y con el detalle que estas mapeando las manzanas, lo que va como landuse=residencial es todo lo que esta adentro de las parcelas (ahora como que lo has mapeado al cordon de la vereda). el cordon de la vereda se mapea como barrier=kerb, y las veredas si queres hacerlo como un multipoligono que el exterior sea el cordon de la vereda y el interior la linea residencial, y ahi se pone para uso de peatones.

y garden:type=residential osm.wiki/ES:Key:garden:type
sino para las apps que consumen datos terminan siendo lo mismo que el Jardín Botanico.

Hola Ferchasa.
Todos los jardines privados debieran etiquetarse ademas con access=private para marcar esa caracteristica. Ver osm.wiki/ES:Tag:leisure=garden

Hi. I disagree with mapping this historic site as power plant as it hasn't produced electricity in more than 100 years. IMO it should be mapped as historic site only.

Thank you, and also please be more careful with some details, specially when editing trunk or primary ways, because when making my edits i also found that some segments were both heading in the same direction, and is a pity that with the effort the community puts in OSM by ill chance some routing app uses the broken data from that short period (I didn't check if that situation was caused by your changesets or changesets from other users)

Hi. "Plaza del Ejercito" is the name of the park, but not the name of the avenue.
What source are you using?

Hi. Why did you map like this? You can drive SW Avenida Sagitario and take Botavara...

Hi. Please remind that car drivers are not the only users of the data. This segment was blocked for cars with guardrails, but pedestrian and bycicles can use it.
