Re: [OSM-dev] New Map Style feedback

Anything with hairpins, small squares or adjacent roads at zoom 15 and
16 (there's plenty in Ticino to point to somewhere nearby, including the
same symptom with tertiary, aka yellow blobs (you can use
http://tile.openstreetmap.fr to verify).

Re: [OSM-dev] New Map Style feedback

[joost schouppe]

I agree that knowing which roads are toll and which aren't is super
interesting. However, there's plenty of trunk roads that are toll in South
America and there are quite a few motorways in France that aren't toll.

Really, I think we need a road-focused mapstyle that shows paved/unpaved
and toll/no toll information first. I don't think trying to convey all of
this in OSM-carto is ever going to work.

Re: [OSM-dev] New Map Style feedback

[Paul Fox]

i'm mostly a read-only participant on this list, but i do have a
question:  i'm currently seeing several places where the map
style changes based on my zoom level.  i assume this is a caching
problem, likely in my browser (google chrome).  should i be
surprised at this?  it's a little disconcerting when the style
of a road changes while zooming in or out, or at a single zoom
level at a tile boundary, as in this screenshot:
http://www.foxharp.boston.ma.us/tmp/sr48-screen.png
(at other than zoom 16, the SR48 is amber, not red.)

[OSM-dev] Master class in map style writing

[Andrew Hain]

Following the release of the new map style, would anyone who is familiar
with writing map style sheets for OSM-based rendering be willing to explain
the skill of doing so to people who are interested in creating their own
style but may not know where to start?

I'm one of the contributors to osm-carto style. We use the CartoCSS 
notation, which is more readable than standard XML notation used in some 
other OSM-based styles. Our style is used as a default on OSM.org and 
one of its goals is to be easily customized and it would be good if we 
have more contributors, so I guess this is a good place to start. Some 
essential informations about osm-carto are here:


https://github.com/gravitystorm/openstreetmap-carto/blob/master/README.md
https://github.com/gravitystorm/openstreetmap-carto/blob/master/CARTOGRAPHY.md
https://github.com/gravitystorm/openstreetmap-carto/blob/master/CONTRIBUTING.md

I'm not a programmer nor a HTML/CSS styler, so my code tend to be rather 
basic, but still it's a lot of fun to try to express my ideas. One could 
learn a lot by looking at the code itself and comparing it with the 
rendering output, but I think the best think is just to play with it 
yourself.


We don't have an installer to make it super easy, but we have some 
installation instructions:


https://github.com/gravitystorm/openstreetmap-carto/blob/master/INSTALL.md
https://github.com/gravitystorm/openstreetmap-carto/issues/657#issuecomment-121279334

Some practical remarks:

1. TileMill editor is no longer in active development and some people 
use Kosmtik instead, but it requires 64-bit platform (I was not able to 
install it on my 32-bit Ubuntu).


2. It's easiest to use Ubuntu Linux 14.04 as a platform, but with some 
additional repo hacking those instructions will work also for newer 
Ubuntu versions.


3. I was also able to partially install it under Windows, but I don't 
know if this setup really works because my friend didn't like Cygwin 
(which is needed for data importing tools).


4. It's better not to start with importing the whole planet dump, 
because it will eat your drive, memory and CPU alive! Most of the time I 
work with my home city and it takes about 10 minutes to load current 
dump. Importing slightly stripped planet dump took me more than 24 
hours. If you're not sure, you can always start with the Luxembourg PBF, 
because it's a whole country, but it has less data than my home city for 
example:


http://download.geofabrik.de/europe/luxembourg.html

5. If you would like to use data from different parts of the world (or 
just different cities), you can switch the database by simple script to 
avoid wasting the time for importing them.


6. It's also possible to manually export data from small selected areas 
from JOSM or directly OSM.org website.


Not a master class, indeed =}, but I hope this will help you start 
playing with OSM data styling. If you have some questions or problems, I 
will try to answer you or at least show where you can learn more.

Re: [OSM-dev] Master class in map style writing

[nebulon42]

For a start you could watch this workshop Andy Allan has given at SoTM 
EU 2014:


https://www.youtube.com/watch?v=W7La0UXec3A
slides: http://sotm-eu.org/slides/76.pdf

There is also a more recent talk from SoTM US 2015 (but not a workshop): 
https://www.youtube.com/watch?v=fO5kWIXmsrA


Another starting point would be the installation instructions of 
osm-carto: 
https://github.com/gravitystorm/openstreetmap-carto/blob/master/INSTALL.md


My recommendation would be to try to get your development environment 
running (database + Tilemill or Kosmtik [I prefer the latter nowadays, 
but Tilemill could be easier to setup for you]), to experiment, and to 
ask questions as you go along.

Re: [OSM-dev] taginfo not always as up to date as it says

[GerdP]

Seems to happen again today. The date on the web page 
http://taginfo.openstreetmap.org/
recently changed to "Data from: 2015-11-03 23:58 UTC",
but all counters are the same as the day before.
(not only for the key highway, also surface, oneway,natural)

Re: [OSM-dev] taginfo not always as up to date as it says

[Jochen Topf]

All logs show that the update worked fine. I don't have the numbers from
yesterday, so I can't compare. Please tell me exactly what you did, which
URLs you asked for with which software, etc? Did you start with a clean
cache (Use shift-reload on Firefox)?
