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 style is a hybrid of Carto and OpenTopoMap. It uses the same SRTM data to generate hillshades and countours, which lie on top of Carto style background.

2. Tile Servers

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

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