Understanding the map - OSM-Carto map reading Q&A
 
Case example collection for SotM 2021 workshop Understanding the map - OSM-Carto map reading Q&A (https://pretalx.com/sotm2021/talk/7SUKCQ/).
 
See https://wiki.openstreetmap.org/wiki/User:Imagico/Understanding_the_map_SotM2021 for an alternative version of this list and more detailed explanations.
 
Case Examples:
 
Please enter case examples below here - see the sample entries of how to do so. For easy management please always add new entries at the bottom. You are welcome to ask anything related to the style - however i am going to pick those case examples i consider most interesting for a wider audience to discuss in the workshop. You are also welcome to indicate your interest in case examples added by others by adding your signature to those.

  • Topic of interest here: "There is nothing there". In very remote/low population areas, features such as tracks become  very important at low zoom levels (as in this example). But that is not generalisable. Any thoughts?

MichaelCollinson: this map: https://wikimap.wiki/?base=map&lat=0.0000&lon=-0.0000&showAll=true&wiki=enwiki&zoom=3 uses the same concept. it requieres a lot of preprocessing, giving aevery coordinate a weight based on density. you could adapt the calculation to ... well, calculate an isolation level and render based on that.
 
------------------------
It is possible to sho the "Null island"  in the Map?
https://www.openstreetmap.org/node/3815077900#map=19/-0.00020/-0.00012&layers=D
https://www.ndbc.noaa.gov/station_page.php?station=13010
 
you mean, the buoy? 
Yes!
I guess you can just add that...
the data is there, just not rendered. if we render that buoy, we have to render them all... or maybe all man_made=monitoring_station... I don't think so
OTOH, I would bring that up as a issue on the style
- Thanks!- 
 
Is it a deliberate decision not to draw zebra (and other) crossings on top of the roads they cross?
 
osm.fr does it
answered in another way: open an issue
 
is this recorded?
 
it was experimentally recorded by the SotM team - they're not making any promises :)
There also might be some private recordings
