Currently we offer OpenStreetMap-Carto and OpenTopoMap based maps with various language labels. We also provide following route overlays: bus, bicycle, subway and train.
To explore all maps that we offer, please visit Map Explorer.

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 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 TracesMap.com)
  • 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

Misc

  • 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 four high performance rendering servers and two caching edge servers.
Two edge servers handle traffic based on user locations:

  • Singapore node: Asia and Oceania.
  • Germany node, serving rest of the world.
  • See DNS Checker for real time config.

    3. Tile Update Policy

    Most of the tiles are prerendered. With limited resources, it is difficult to keep an up-to-date map repository in a short period of time, like OpenStreetMap.org does.

    Our strategy is to rerender recently-accessed areas more frequently. We distinguish active and inactive areas. Active areas are rerendered approximately every 21 days. Inactive areas are rerendered in longer period, for example one month to six months.

    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, let us know by mentioning @tracestrack on Twitter, or send us an email at info(at)tracestrack.com.

    The source code of Tracestrack Carto style is not open. We plan to make it open source in certain moment in future.

    We 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
