OpenStreetMap (OSM) relies on community contributions to improve its map data. A simple yet impactful way to start contributing is by adding official website tags to local shops and amenities. These tags help enrich the map with additional information such as contact details and opening hours, which are often available on official websites.
To begin, users should create a free OSM account and verify their email. Next, download and install JOSM, a Java-based editor that offers advanced features and plugins to streamline editing.
After launching JOSM, download map data for a familiar, small area—ideally no larger than a few city blocks. Use the built-in filter to isolate shops and amenities lacking website tags. Then, install the Website Wizard plugin, which assists in finding official websites.
Using the plugin, search for the official website of a selected place by querying with its name and location. Avoid using social media or aggregator sites; only official websites should be added. Once identified, add the website URL tag to the place’s data.
Finally, upload your changes back to OSM with a descriptive comment and specify the data source as a survey. This contribution will soon be integrated into various OSM-based services, benefiting users worldwide.
This process not only improves map quality but also introduces contributors to powerful tools within JOSM. Users can expand their efforts by adding other useful tags or encouraging others to participate, helping OSM evolve into a more comprehensive global map.
