If a related issue does not exist, submit a new one. Please include as much of the following information as is relevant:
- Sample data to reproduce the issue.

If you have a question or a suggestion not related to a bug iTowns, you can search the iTowns discussions.

We recommend the use of iTowns discussions for suggestions and questions. However, there is another way of suggesting imrpovements or asking questions, which is through iTowns mailing lists. There is a user mailing list and a developer mailing list.
You can subscribe to the mailing lists here:

The mailing list archives are here:
- Developer: https://lists.osgeo.org/pipermail/itowns-dev/
