About

The “basic” roads at 10m scale are from CEC North America Environmental Atlas with no attributes and only 1 scale rank class. The “basic” is only available in North America due to the source. We’d like to expand this to world wide, do you have data to contribute?

The “supplementary” data in North America includes preliminary scale ranking and full list of attributes and is graciously contributed by XNR Productions.
