Overview

The Covid-19 Datenhub is a German ArcGIS-based platform that provides maps, datasets, and applications related to the Covid-19 pandemic. It is free to access and does not require authentication for basic data queries. You can use it to retrieve geospatial Covid-19 data for analysis, mapping projects, or research applications.

Beginner Tip

This platform uses the ArcGIS REST API format — to query datasets, append /query?where=1%3D1&outFields=*&f=json to any feature layer URL to retrieve records in JSON format.

Available Data

case counts and statistics
vaccination data
geographic breakdown
historical trend data

Common Errors & Troubleshooting

Error parsing response or unexpected HTML You may have requested the base URL without proper ArcGIS REST API parameters.
✓ Always append query parameters like ?where=1=1&f=json to feature layer URLs; the base hub URL returns an HTML page.
exceededTransferLimit in response The query returned more records than the server allows in a single response.
✓ Use the resultOffset and resultRecordCount parameters to paginate through results in smaller batches.
Slow or timeout response Querying all fields across the full dataset without filters is resource-intensive.
✓ Add a where clause to filter by date or region, and specify only needed fields using the outFields parameter.
