Ontario Vector Topographic Data Cache

The Ontario Vector Topographic Data Cache is a collection of topographic data, that has been preprocessed for fast, seamless display at predefined scales.

The topographic data includes constructed and natural features that make up Ontario’s landscape.

The cache provides limited data from areas outside Ontario’s boundaries, such as the United States and adjacent provinces and territories.

Technical information

Two versions of the Topographic Data Cache are available:

The traditional raster version is available for a variety of GIS applications and is updated annually.
The vector version is suitable for online web map applications as well as modern GIS software and is updated twice a year.

Contributing data layers may have different maintenance and update cycles.

Some cache layers have been processed in a way that makes it easier for them to be displayed in a mapping product. Other layers are unchanged from the authoritative data.

The cartographic symbology used in the data cache is intentionally muted to allow users to showcase their data.

The Ontario Vector Topographic Data Cache is created from many source datasets, which are described in the Ontario Vector Topographic Data Cache user guide. If you are interested in getting this authoritative data, you can download it from the Ontario GeoHub.

For instructions on getting a copy of either version of the cache for use in mapping applications, visit the Ontario GeoHub.
