OpenStreetMap Tiles

A tile renderer for OpenStreetMap that provides the following tile sets:

Road overlay

Live slippy map and tile server

A live version is running at https://osm-tiles.james-ross.co.uk/.

Road overlay

This tile set is an overlay (meaning the tiles are transparent where there is no data) which renders roads (highways) from OpenStreetMap according to their various tags, including:

cycleway=lane =opposite
cycleway:left=lane
cycleway:right=lane
highway=motorway =trunk =primary =secondary =tertiary =unclassified =residential =service =motorway_link =trunk_link =primary_link =secondary_link =tertiary_link
lanes=*
oneway=yes
parking:lanes:both=parallel =diagonal =perpendicular
parking:lanes:left=parallel =diagonal =perpendicular
parking:lanes:right=parallel =diagonal =perpendicular

Limitations

Only layer=0 or !layer ways are rendered for now.
Only zoom levels 16 through 22 are supported.

Current rendering

Notes

Each tile is rendered on-demand, but the underlying data is cached in memory in zoom level 14 chunks.

To do

Separation and correction of way end nodes at junctions (to align lanes)
Calculations for layer!=0, bridges, tunnels
Calculations for bus, PSV (public service vehicle), other specialised lanes
Calculations for placement=*
Calculations using turn lane markings
Calculations for width
Display tapering of road width/lanes
Display parking lanes/bays
Display bridges, tunnels
Display bus, PSV, other specialised lanes
Display turn lane markings (left/right turn arrows, etc.)
