Road catalog data distribution
The road catalog the GTGO app actually uses — sections, roads and stop-by spots — is published as-is, the same artefact that ships with the app.
Licence
This data is made available under the ODbL 1.0 (Open Database License). Any Derivative Database you create from it must itself be made available under ODbL 1.0 or a compatible licence, and the attribution notices must be kept intact.
