OpenStreetMap (OSM) relies on community contributions to enhance its global map data. One simple yet impactful way to contribute is by adding official website tags to local shops and amenities. These tags help enrich the map with additional information such as phone numbers, opening hours, and contact details, which are often available on the official websites.
To get started, first create a free OSM account and verify your email. Next, download and install JOSM, a Java-based editor that offers powerful tools and plugins for editing OSM data.
Once JOSM is running, download map data for a familiar, manageable area—ideally no larger than a few city blocks. Use the download dialog to select and retrieve this area.
To focus on relevant places, apply a filter that shows only shops and amenities lacking website tags. This narrows down your editing targets.
Enable the Website Wizard plugin within JOSM to streamline the process of finding official websites. This tool allows you to search for a place’s official site using DuckDuckGo, helping you avoid unreliable sources like social media or review sites.
After locating the official website, add its URL as a website tag to the corresponding place in OSM. When finished, upload your changes with a descriptive comment and specify the data source as a survey.
This straightforward process not only improves OSM’s data quality but also introduces contributors to the capabilities of JOSM and the value of detailed tagging. Contributors can continue enhancing their area by adding other useful tags or encouraging more people to participate, helping OSM grow into an even more comprehensive and reliable map resource.
