A tile renderer for OpenStreetMap that provides a dynamic overlay tile set.

• Road overlay
• Rail overlay
• All overlay
• Limitations and notes
• To do

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

A test page for any OpenStreetMap tags is at https://osm-tiles.james-ross.co.uk/test.html.

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_lane
• cycleway:both=lane =opposite_lane
• cycleway:left=lane =opposite_lane
• cycleway:left:oneway=no
• cycleway:right=lane =opposite_lane
• cycleway:right:oneway=no
• highway=motorway =trunk =primary =secondary =tertiary =unclassified =residential =service =motorway_link =trunk_link =primary_link =secondary_link =tertiary_link
• lanes=*
• lanes:backward=*
• lanes:both_ways=*
• lanes:forward=*
• layer=*
• oneway=yes =-1
• parking:lane:both=parallel =diagonal =perpendicular
• parking:lane:left=parallel =diagonal =perpendicular
• parking:lane:right=parallel =diagonal =perpendicular
• shoulder=yes =both =left =right
• shoulder:both=yes
• shoulder:left=yes
• shoulder:right=yes
• sidewalk=both =left =right
• verge=yes =both =left =right
• verge:both=yes
• verge:left=yes
• verge:right=yes

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

• gauge=*
• railway=abandoned =construction =disused =funicular =light_rail =monorail =narrow_gauge =preserved =rail =subway =tram

• Only zoom levels 16 through 22 are supported
• Each tile is rendered on-demand, but the underlying data is cached in memory in zoom level 14 chunks

• Separation and correction of way end nodes at junctions (to align lanes)
• 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.)
• Display of footpaths
• Display of railway platforms
