Help us keep the map fresh
We don't own the data — it's completely open and lives on OpenStreetMap. Here is a short guide to help you to start contributing to BTC Map in your community. Every fix counts.
Find your community or country
Open the Maintain tab
Every country and community page has one — it lists places that need your help.
Pick local issues you can fix
Scan the list. Outdated opening hours, missing coordinates, wrong names — click the help button on each issue for guidance. Small fixes make a big difference.
Fix them on OpenStreetMap
Create a free OpenStreetMap account and edit the map directly. Changes usually appear on BTC Map within an hour.
