Street names in Brazil / Proposal
Michael Schneider
I've been traveling Brazil and I noticed a issue that could be
improved with little effort: the rendering of residential street
names.
The Situation:
a) The majority of residential street names in Brazil is of one of
these types:
Rua : normal residential street
Avenida : longer and/or wider residential street
Travessa: short, narrow residential street
b) In addition, many street names refer to historic events like
revolution(s), independence etc. Officially, (e.g. by the postal
service), dates are spelled out ("Street twenty of september").
c) Other streets refer to important (mostly military) persons, the
rank ("General" etc) being part of the street name., but abbreviated
on the street sign.
The problem:
Currently, OsmAndMapCreator builds files that display the complete
street name on the map. Especially for short streets (Travessa) with
"date"-names, the complete Name gets very long and is only renderd at
very high zoom levels.
Example: go to google maps and look up "Travessa Dezesseis de Maio,
Rio de Janeiro, Brasil"
What do commercial map-makers do?
Some of them drop the street category (Rua/Avenida/Travessa)
altogether, some use abbreviations (R/Av/Tv). Most of the commercial
maps do not spell out dates and use "16" instead of Dezesseis.
I propose that OsmAndMapCreator does the same and shortens
"Travessa Dezesseis de Maio" to
"Tv 16 de Maio"
I would like to build a version of OsmAndMapCreator to try this out,
but I could not find the place where the street name to-be-rendered is
processed. In net/osmand/data/preparation/IndexAddressCreator.java
there is a method to normalize Street names, but this does not affect
the rendered map, but only the search index.
Where should I look in the sources?

when the data is flowing from the raw osm (or protobuf file) to the
map.obf isn't there a way to place a filter for residential roads
somewhere?
