[Talk-br] Road network improvements in Brazil

[Fernando Trebien]

Hi Andrew,

Classification is a hotly debated topic that surely deserves more
attention, with many controversial proposals as written in the
article. The system proposed in the article dates back to 2013 and has
been heavily criticised, producing fragmentary networks in regions
with many unpaved roads (most places in Brazil except the most
developed regions along the coast). Recently there has been a very
interesting forum thread focused on rural highway classification in
the southermost state of Rio Grande do Sul [1], where mappers have
agreed to diverge from the system proposed in 2013 (what's on the wiki
right now).

The wiki does not talk about urban street classification. The
Brazilian community has agreed to try to follow municipal plans as
closely as possible. So far, only the street classification in the
region of Porto Alegre is documented in detail [2]. We have gathered
the official street classification of many cities [3], but most have
not been reviewed yet, a few have been reviewed but not documented. In
Santa Maria [4], some classification has been done but the mappers
have stated that they did not base their work on the community's
agreement, instead following an approach more similar to that of 2013.

My team is interested in doing some work on the road network in Brazil on OpenStreetMap, things like adding missing roads, making sure roads connect properly, fixing incorrect alignments with GPS traces, ensuring road classifications are consistent, and other similar issues.

Also I saw these guidelines about road classifications, are they the most recent classifications used by the community, or are there any others we should be aware of? https://wiki.openstreetmap.org/wiki/Pt:How_to_map_a
