I’ve noticed that the main map displays only a few cities in North America at lower zoom levels, like zoom=4. I’ve tried to see if I can find any particular key/tag values that determine whether a city is displayed or not at that level, but I can’t seem to determine any pattern.
It would be nice to see Vancouver show up on the map with the other major N American cities.
Somewhat related to this, wouldn’t it be useful to have a category something like “metropolis” as a category above “city”? In my area we have a number of cities in the metropolitan Vancouver area. I’d like the lower zoom levels to show the area as Vancouver, instead of a close group of separate cities. As you zoom in, the details could be revealed.
I’m fairly new to OSM, so perhaps there are some features I’m just not aware of.
