Understanding the map - OSM-Carto map reading Q&A

This page is for collecting case examples from interested mappers for the workshop Understanding the map - OSM-Carto map reading Q&A at this year's SotM conference.

The workshop is going to take place on Sunday July 11 at 12:15 UTC on Track 2

Submitting a case example

The kind of case example i am looking for in this workshops are links to specific places on the map on openstreetmap.org for the purpose of me in the workshop discussing and explaining the cartography of the standard style in those case examples. From the workshop description:

This is going to be an interactive session where participants can submit case examples (in the form of links to specific examples on the map) to be discussed. The focus of the discussion will be on explaining the design of the map and what cartographic and technical considerations stand behind it.

The aim is for participants - both newcomers and experienced mappers - to better learn how to read the map, to better understand the cartographic and social challanges of designing a rich, global, real time updated map based on OpenStreetMap data for a truly diverse international and multi-cultural audience and hopefully to get some participants more interested in community map design and to encourage them to either contribute to OSM-Carto or to contribute to or start their own regional or thematic map design projects.

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.

If you don't feel comfortable in editing the wiki - there is also an Etherpad where you can likewise submit case examples.

  • 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?

I have not answered this during the workshop so quickly: Yes, in principle buoys could be rendered at the highest zoom levels if there is consensus among mappers how to tag them (this seems to be both man_made=monitoring_station and seamark:type=buoy_special_purpose - which looks to be likely not a very well established tagging). But there is little point in that for features in the middle of the ocean where no one zooms into that far. And showing them earlier would crowd the map too much in near coastal areas obviously.
