Why raster maps

Raster maps are mature and easy to support on mobile/desktop apps and websites. With 512px tile size, maps can also be sharp on HD screens. Raster maps can show more details on low zoom than vector. When raster data sources, such as hillshades and satellite data is involved, raster map may also perform better than vector maps.

1. Map Style

Tracestrack Carto style is forked from openstreetmap-carto on Jan 12, 2021. Following is a main list of changes:

Removed rendering

  • Power lines
  • Underground subways

Updated rendering

  • Buildings are visible from Z17
  • Simple 3D buildings
  • Pedestrian areas and ways
  • Simplified footway/cycleway/path
  • Man-made bridges
  • Improved high density highway rendering (e.g. Cairo: See in
  • Trees and tree rows

Added rendering

  • City districts: place=borough
  • Sea and ocean: place=seaplace=ocean
  • Aquaculture areas: landuse=aquaculture
  • Tourism attractions: tourism=attraction
  • Busways: highway=busway
  • Solar farms and wind farms: power=plantplant:source=solarplant:source=wind
  • Highway/railway embankment: embankment=yes
  • Government landuse: landuse=governmental landuse=civic_admin landuse=institutional
  • Pitch sport icons: leisure=pitch


  • Use place:CN for Chinese place names
  • Use correct CJK fonts in Japan and Taiwan
  • Better line breaking for longer CJK place names

Tracestrack Topo is a topographic map style derived from Carto and inspired by OpenTopoMap. It makes use of several DEM data sources to generate hillshades and countour lines. This map style is a featured map on

2. Tile Servers

Currently, Tracestrack has three high performance rendering servers and several edge servers.

Our DNS routes traffic to the best available edge servers. There is failover setup for all edge servers to minimize downtime.
See DNS Checker for real time config.

3. Tile Update

The database is synchronized with OSM everyday. Tile cache is rerendered roughly every 10 days, depending on the number of updated regions. The following map keeps track of the last two update areas. Red marks the current update areas and gray marks the previous ones.

4. Map Style Updates

We love to make our map style meet users' needs. If you want to render new tags or update current styles, please open issues on Github.

The source codes of Tracestrack Carto and Topo styles are partly open. You can find them on Github.

We also take issues and pull requests from openstreetmap-carto as sources to improve the maps. Following is a list of issues and PRs that influenced Tracestrack Carto style:

  • Fix shop=car_repair label/icon colour mismatch (brown) #4536
  • added rendering of amenity=parcel_locker #4512
