I have just upgraded to gigabit internet at home. Can really recommend iWay.ch! Downloading a large file from my hetzner which has also a 1 Gbps line gives this:

Google Maps Bretagne
Bretagne is a nice example for bad road network rendering if you select minzooms purely based on semantics like the OpenStreetMap highway tag. Roads alternate here between highway=trunk and highway=primary. If you select now only the highway=trunk roads, you get a lot of gaps...

I'm experimenting with highway generalization for low zoom levels. In this screenshot I made the lines collapse by looking for close by points up to a certain radius, then taking the midpoint of those. Doing this multiple times converges the points and sort of smooths lines...

I am looking a bit into vertical text layout of Japanese in MapLibre GL JS. Interesting how some characters are displayed with 90 degree rotation in vertical text. For example the string "(東京タワー…)" becomes this

Selecting which roads to display on a map at a given scale is an interesting problem. One approach is the stroke-mesh method which prunes roads based on local density and length of dead-ends. Have a look at Benz and Weibel 2014 www.zora.uzh.ch/id/eprint/10...

Google Maps seems to show links between motorways at all zoom levels, but links from motorway to primary roads seem to be visible only from zoom 12.
Has anyone done something like this with OpenStreetMap data?
