During GSoC 2015 I focused on improving road presentation in the Default OSM map style. This year I am again participating, but with more diverse goals. I am planning to improve performance, reduce rendering order problems and tune mid-zoom level rendering.
mid-zoom level rendering
I started with work on improvements to mid zoomlevels (z6 to z9). During search for the best and most promising ways to improve rendering, starting from trawling through reported issues. I also prepared and submitted some additional tweaks like rendering names for barriers, fixing viewpoints and forests and shops and other.
I am also like during GSoC 2015 preparing a comparison between the current map style and alternatives.
A bit of history
There are some visualisations showing how data was added to OSM. But I have neither seen nor found something similar for a map style. So, for start of next big series to the map I made a display of what was changed in the past.
Visualisation are available for z18
I selected Weybridge as location as map of this place was the first OpenStreetMap-based map to go on Wikipedia.
As usually testing and review is welcomed for open pull requests, especially one considering rendering names for barriers and an associated popular tagging mistake.
I am considering to look more for inspiration/comparison in printed maps. I looked for online sources and for now I found surprisingly small number of contemporary maps that would display sort-of-similar set of symbols as Default OSM style, with scale within z5 - z10 range.
But I found nothing highly useful. For now

are the best. Is anybody aware about maps or database of maps allowing to find maps similar in content to Default OSM Style, with scale within z5 - z10 range?
Thanks to Paul Norman for simplified osm2pgsql database dump. Without that resource obtaining database for lower zoom levels would be far more complicated.
