OpenStreetMap Tiles

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.

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_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

Rail overlay

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

All overlay

Limitations and notes

• 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

To do

• 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
