Improving OpenStreetMap in Québec: preparing a verifiable contribution

Choose a small correction, check permitted sources and publish understandable changes.

Check before acting

Do not copy another map without permission or publish unnecessary personal information.

Start with a small correction

Create a mapping account and follow the guide for the chosen editor. Start with a known, verifiable feature rather than a large restructuring. [1]

Check reuse rights

Information visible on a commercial map is not automatically reusable. Use observations or sources compatible with project rules and retain their provenance. [2]

Review before publishing

Review the existing object, attributes and proposed change. Use editor guidance and clearly describe the contribution so other mappers understand what changed. [1]

Handle imports separately

A bulk import requires review of guidelines and licence compatibility. Present the dataset to the community before automating a series of changes. [3]
