Kölner Adressen API

Description

This API provides access to a dataset containing addresses within the city of Cologne. It includes geospatial information and various formats for data retrieval, enabling navigation and analysis of geographic data related to buildings and urban structures.

What can you use it for?

Map Cologne addresses, build a local address search, or join addresses with neighbourhood statistics — quick project ideas to try. You can download complete files or query the public ArcGIS FeatureServer for GeoJSON. The data includes coordinates for each address and is published by the city for free use. Note the FeatureServer enforces a per-query record limit (use paging for large extracts).
