IBGE Street Names
This layer provides some Brazilian street names available from IBGE's Base de faces de logradouros
While IBGE doesn't call this data as "street names", we are using it in this way so that users can have a better understanding of what this data is really all about.
A description of the data can be seen here (PDF in Portuguese).
This layer is kindly hosted by Mapbox.
License
IBGE stated that all data in their site are "public domain with attribution required", so it is listed in the OSM Contributors page. Optionally, add the tag source=IBGE to all data from this layer (or, better yet, use source:name=IBGE in the changeset tags).
Using the layer
JOSM
JOSM already has this preset available when you download an area in Brazil. All you have to do is activate it, by selecting Imagery → IBGE Street Names (or Camadas → IBGE Nomes de Ruas if you are using JOSM in Portuguese)
You can use source:name=IBGE in the changeset tags when uploading the data.
iD Editor
For now you can manually use the layer in iD using the following URL as a Custom Background:

Further information
Name formatting
The names were formatted in the best possible way, including correcting the most common accented names.
Streets that had a descriptive name (such as "No Name Street") were left nameless.
