The Canada Basemap – Transportation (CBMT) is a vector tile service that provides spatial reference context with an emphasis on transportation networks across Canada. It is designed especially for use as a background layer in a web mapping application or geographic information system (GIS).

Access: Access is free of charge under the terms of the Open Government Licence - Canada.

Data Sources: Data for the CBMT is sourced from multiple datasets.

- Topographic data of Canada - CanVec Series.

- “Automatically Extracted Buildings” GeoBase (a raw digital product in vector format automatically extracted from airborne Lidar data, high-resolution optical imagery or other sources).

- Open Street Map (OSM) data available under the Open Database License (https://www.openstreetmap.org/copyright).

- Official names from the Canadian Geographical Names Database (CGNDB).

Geographic Coverage: CBMT has complete coverage of the world, with full datasets in Canada and only partial data in other parts of the world including boundaries, Country Names, and major cities.

Data Update Frequency: Updates are applied monthly to reflect the latest updates in the source datasets.

Projection: Data is provided in the EPSG:3857 (WGS84 Pseudo-Mercator) projected coordinate system.

Layer Access:

- CBMT is accessible via the ArcGIS Online item link with the applied style or it can also be accessed directly with the default style using the following Vector Tile Server:

https://tiles.arcgis.com/tiles/HsjBaDykC1mjhXz9/arcgis/rest/services/CBMT_CBCT_3857_V_OSM/VectorTileServer

- In QGIS or other applications that require the style JSON, the following link can be used:

Use Cases: This layer is suitable for use in any map as a basemap layer and can be modified to meet the needs of the project by editing the JSON style in the Vector Tile Style editor.

Additional Versions:

- A geometry-only version (CBMT3857GEOM) and a text-only version (CBMT3857TXT) are available.

- French versions of the basemap are accessible via the Carte de base du Canada - Transport 3857 V (CBCT3857).
