<br>
En
la comunidad Brasileña ya tuvimos muchas discusiones sobre la
clasificación de carreteras y calles. Llegamos en una
definición
que es muy buena para vías rurales, pero, en mi opinión, no es
todavía muy clara para las vías urbanas (los principales
conflictos
son entre calles residenciales y
terciarias):<br>
<br>
<a class="moz-txt-link-freetext" href="http://wiki.openstreetmap.org/wiki/Pt-br:Guia_de_Mapeamento_do_Territ%C3%B3rio_Brasileiro#Classifica.C3.A7.C3.A3o_de_vias_.28original.29">http://wiki.openstreetmap.org/wiki/Pt-br:Guia_de_Mapeamento_do_Territ%C3%B3rio_Brasileiro#Classifica.C3.A7.C3.A3o_de_vias_.28original.29</a><br>
<br>
Hay
también un flowchart bastante complejo:

<br>
El
problema que veo con la propuesta de clasificación de acuerdo
con la
importancia da la vía es que en comunidades con muchos
colaboradores
puede generar muchos conflictos, pues la importancia de una
vía no
es una definición objetiva. Pero si ya está siendo utilizada
en
África, no soy contra que sea utilizada en países con pocos
colaboradores y con una infraestructura de carreteras poco
jerarquizada y definida.<br>

Hello Latin America,</p>
<p dir="ltr">There were a lot of reactions to my earlier post
about mapping the quality of roads in Latin America. I hoped
we could talk about this at SOTM, but that didn't happen. So
here I'd like to revive the discussion. I learned a lot since
then, mostly thanks to Marco Antonio. Estoy escribiendo en
inglés como parece más fácil para los brasileños. Puedo
traducir si le hace falta a alguien.<br>
</p>
<p dir="ltr">What I'd like us to do now:<br>
- As a Latin community we keep mapping surface and show off
the progress we make. I'll try to make some statistics about
the progess we make (and publish them on <a
moz-do-not-send="true" href="http://global.swing.eu">global.swing.eu</a>
)</p>
<p dir="ltr">- As a Latin community we try to get surface
included in the standard mapnik map. I made a simple mock-up:<a
moz-do-not-send="true"
href="https://github.com/gravitystorm/openstreetmap-carto/issues/110#issuecomment-66274450"
target="_blank">https://github.com/gravitystorm/openstreetmap-carto/issues/110#issuecomment-66274450</a>.
From the reactions, it seems that they will only consider a
proposal which is already almost ready for inclusion in the
main code. So that means we have to get a Tilemill running and
play around with the stylesheet ourselves. I've got the
History Renderer installed, and I'll try to play a bit with
the xml stylesheet that uses... We would have to work out most
of the details, and maybe even make changes to the style of
tunnels or planned roads. If this proposal is rejected (which
I have a feeling is quite possible), we might have to start
playing it politically. Maybe trying to get Mapbox and HOT
involved.</p>
<p dir="ltr">Anyone have some experience with Tilemill? Or
another tool to make nice mockups with OSM data, based on
standard Mapnik style?</p>
<p dir="ltr">In the longer term:</p>
<p dir="ltr">
- Develop an Afro-Latin tagging scheme. Now there are many
different national interpretations of road tagging. That's not
a good idea, as a lot of our data users are international. The
African tagging scheme is good and simple: basically a road is
classified higher if it is more important. Quality of the road
does not count. So a terrible dirt road is still primary if it
is the only connection between major cities. But this tagging
scheme does not use the trunk road classification. My proposal
would be to use this trunk road tag, but only for the most
important roads that are not freeways, that are paved and that
are at least two lanes wide. With this slight adaptation, I
think we could happily map Latin America. And it would stick
very close to current practice and the African practice,
making it easy to have a common Afro-Latino scheme. In turn,
that should make it easier to push for changes relevant to our
community. Anyway, most people seem to agree that the only
valid reason to map a road in a higher classification is that
the road is more important (see eg <a moz-do-not-send="true"
href="http://www.openstreetmap.org/user/Mark%20Newnham/diary/20736"
target="_blank">http://www.openstreetmap.org/user/Mark%20Newnham/diary/20736</a>).</p>
<p dir="ltr">- Even if after over six years, we do manage to get
mapnik to show road quality, I still see a use for a Latin
mapview. I think the Mapa Ecologico is a great example. Here
rivers and roads get mapped much more prominently at higher
zoom levels, which for the much less populated continent makes
a lot of sense. I talked to Linhares and he would like to
share his stylesheet. How about we make a Latin OSM portal
with our own map style and maybe even a more pronouncable
name, like <a moz-do-not-send="true"
href="http://www.MapaMundiAbierto.org" target="_blank">www.MapaMundiAbierto.org</a>
or <a moz-do-not-send="true"
href="http://www.OtroServiciodeMapas.org" target="_blank">www.OtroServiciodeMapas.org</a>?
That would allow us to highlight things which are more
important in this part of the world. After a presentation in
Bolivia, I got the idea that they really did get the point
when someone asked if we could make a mapa de las fiestas! Why
not : )</p>
<p>So, who wants in?</p>
