Querying OpenStreetMap Data with the Overpass Turbo Wizard

If you’re new to OpenStreetMap (OSM), writing Overpass queries from scratch can seem intimidating. Fortunately, Overpass Turbo provides a built-in Wizard that generates queries automatically based on simple search phrases. This makes it easy to retrieve geographic data without learning the full Overpass Query Language (Overpass QL).

What is the Overpass Turbo Wizard?

The Wizard is a feature in Overpass Turbo that converts plain-language search terms into valid Overpass queries. Instead of manually writing code, you can describe the data you want and let the Wizard generate the query for you.

For example, if you want to find schools in the current map area, you can simply enter:

text amenity=school

The Wizard will create the corresponding Overpass query automatically.

How to Use the Wizard

1. Open Overpass Turbo.
2. Zoom the map to your area of interest.
3. Click Wizard in the toolbar.
4. Enter a search expression such as:

amenity=hospital

or

shop=supermarket

1. Click Build and Run Query.
2. The matching features will appear on the map.

The generated query can also be viewed and edited if needed.

Example

Suppose you want to locate restaurants in the visible map area. Enter:

amenity=restaurant

The Wizard generates an Overpass query and displays all matching restaurants from OpenStreetMap within the current map view.

Exporting the Results

After the query runs successfully, you can export the results for use in GIS software or other applications.

1. Click Export.

2. Choose a format such as:

   • GeoJSON for web mapping and GIS tools.
   • KML for Google Earth.
   • GPX for GPS applications.
   • Raw OSM Data for OpenStreetMap-based workflows.
3. Save the file to your computer.

GeoJSON is the most commonly used format because it works well with tools like QGIS, Leaflet, and Mapbox.

Conclusion

The Overpass Turbo Wizard is the easiest way to query OpenStreetMap data without learning complex query syntax. By entering simple tag-based expressions such as amenity=school or shop=supermarket, you can quickly retrieve map features and export them in formats suitable for analysis, visualization, and GIS projects. For beginners, the Wizard provides a fast and practical introduction to the power of OpenStreetMap data extraction.

Note

• If a query fails because it exceeds the execution time limit, increase the timeout value (in seconds) in the generated query and rerun it.
• If you are unfamiliar with OpenStreetMap (OSM) tags, refer to the following resources to explore available tags and their usage:
  • OSM Taginfo
