"source" es atributo del changeset.
¿Que sentido tiene repetirlo en cada elemento?
No aporta nada y solo incrementa el espacio usado por los datos.

Anzani y Caracas no estan conectadas. Hay un pequeño kerb en el medio de Rivera.

Si queres unir Rivera y dejar una sola via (que es discutible), tenes que agregar las respectivas restricciones que los vehiculos tienen que respetar.

Gracias Pablo por la confirmacion. Quedaron corregidas.

No, I hadn't check all changesets.
I just raise a warning flag to try to improve the changes based on this KG 2016 survey.

No estuve. :-( Reverti un cambio por malas geometrias que hacia pelota varias calles de la zona, pero creo que no es ese que mencionas. sino
changeset/41512686 (obviamente no me acuerdo pero es lo que parece por la historia http://osmhv.openstreetmap.de/changeset.jsp?id=41512686 )

Lo que no entiendo es porque ese detalle de la calle que mencionas quedo mal.

"Anglo" brand (if used with the lion icon) refers to a english teaching services, http://www.anglo.edu.uy/
and the list of sites here http://www.anglo.edu.uy/instituto-centros/anglo-centros-por-departamento/montevideo

The building you map as "Anglo" has a shop and a travel agency in the street level, and the "Anglo" is upstairs
So it should be mapped only as a building, and three nodes, one for "Anglo", one for the shop and another for the travel agency.

The image is right. The building is there and it's not closed, it is in working condition and it is operated by "Banco Republica" (i think for their internal use like archiving documents), but no financial services are offered there. They offer services in sites listed here https://www.portal.brou.com.uy/web/guest/institucional/red-fisica/montevideo

"Santeria" is probably "shop=religion"

"Stadium" (in the context of shops) is shop=shoes

"Cash" and "Pronto!" are shop=money_lender
There are others but dont remember now.

No. Its not apropiate. "Calle Miguelete" is not an historical name, the name is, and always was the same, Miguelete. "Calle Miguelete" is written on old signs, and "Miguelete" is written on the new ones. Not all olds signs have been taken away.

Avenida and Bulevar are exceptions, and also the signs (old and new) shows "Av." and "Bv."

You can also find mixed old signs (not and old name, it's the same name with prefix), for exampe,
in streets Juan Antonio Rodriguez, Prof. Clemente Estable, Magariños Cervantes and Florencio Varela. (Surely there are more that I dont remember right now)

The string "Calle" is only part of the name in a few exceptions, most commonly when the name is a number or a letter. "Calle 7" or "Calle B".

Not exactly. They are always amenity=payment_centre (their main business activity), and also sometimes are amenity=bureau_de_change, so because multivalued amenity is not well interpreted by all consumers is better to be mapped as two separate elements.

surface=sett and not cobblestone is a better choice for this kind of surface.

Most (if not all) surface=cobblestone in Montevideo are errors and should be put in a todo list to evaluate and correct them.

Also, with sett there are several situations, in some strets the smothness is good and aceptable to drive in a car (like this small part), and in others streets "paved" with sett are so bad that if you drive there it will loosen you teeths.

Im talking about the intersection of La Cumparsita and Doctor Carlos Maria Morales.
changeset/43882892#map=19/-34.91417/-56.18046

The old signs says that, but "Calle" is the prefix and not part of the name.
Also In some streets there are mixed signs, old and new, and sometimes the old signs have the old name of the street.

I don't disagree, I just has some doubts.

I dont know without seeing it, most probably is just a new building that advertises some apartaments for sale. You can also see as "Financia Santander" or any other bank.

I will go there next week.

UTE (las oficinas) seria office=company, al igual que las otras empresas publicas.

office=government es gobierno ya sea nacional o departamental, ministerios, u otras unidades del gobierno. Por ejemplo, URSEA, URSEG y AGESIC serian office=government

Le voy a preguntar a @Pablo%20Lorda%20Da%20Costa%20Porto que ha estado mapeando Salto en las ultimas semanas...

The south part should'nt be divided.
Please correct it. And please also change the landuse=grassland in the kerb to barrier=kerb

What is important in that intersection is that there are the four turn left restrictions, no matter the way you came from, you can't turn left.
