A problem, or a pointed question?

Report an anomaly in the relief or the tool, or ask a question more advanced than those covered in the FAQ. We read every email.

The most direct way to reach us:

Before writing with a general question, take a look at the FAQ: it covers the essentials about the tool and the data.

So we can reproduce and fix it, please include where possible:

The area concerned — coordinates (copyable from the map, pill at the bottom-left) or a description of the location (e.g. “near Baie-Saint-Paul”).
What you observe — missing relief, aberrant values, an artefact, a crash.
Your browser and device — e.g. Chrome on Windows, Safari on iPhone.
A screenshot, if the problem is visual.

For any question about the origin or licence of the data itself, the reference remains Données Québec.
