Case study
Cadastre France
Building a map-based platform for French property and cadastral data
Cadastre France helps users find and explore French cadastral parcels, property information, planning documents and related public data through an interactive map.
My role
Working primarily independently within a two-person team, I built the application from provided Figma designs through frontend, backend, data integrations and production deployment.
Key contributions
- Building the application from scratch using Laravel and Livewire
- Implementing an interactive cadastral map with Leaflet and OpenStreetMap
- Developing address, city and parcel search
- Integrating DVF, Sitadel, API Adresse and Géoportail de l’Urbanisme
- Displaying transactions, permits, demolitions and planning information
- Implementing region-based filtering with predefined neighboring regions
- Building lead-generation workflows and PDF property reports
- Handling production deployment and ongoing improvements
Results
The result was a complete production platform bringing cadastral maps and information from multiple public sources into one accessible interface.
