Open City Planner

Open City Planner is a civic-tech web application that makes spatial analysis accessible to non-specialists. It combines OpenStreetMap data with municipal open data in an interactive browser interface, allowing users to explore districts, search locations, and inspect spatial metrics. The tool is designed for urban planners, community members, and civic organizations who need to understand city structure and land use without specialized GIS expertise.

Users can search addresses and businesses, select districts to view polygon data and statistics, and filter mapped areas by attributes like industry and floor space. The project uses Flensburg, Germany as its reference implementation. The developers indicate the project incorporates AI tools in its development process.
