Système de notation immobilière

Each property receives scores across 7 categories (Safety, Education, Transport, Environment, Urban Development, Livability, and Overall). Scores are calculated on a 0-100 scale using proximity metrics, quality indicators, and quantity data from 50+ sources including Google Maps, EU Copernicus satellites, AFAD, and real-time air quality sensors.

Our scoring engine combines data from Google Places (nearby amenities), Google Maps (distances, travel times), AFAD (Turkey earthquake data), Google Air Quality API (real-time AQI), EU GHSL (urbanization trends), Google Earth Engine (SRTM terrain, JRC flood risk, Dynamic World land cover), Open-Meteo (climate), and Claude AI (executive summary generation).

The Overall Score is a weighted composite of all category scores. Safety and Education are weighted highest, followed by Transport, Environment, and Livability. It gives buyers a single number (0-100) to quickly compare properties — higher is better. The weighting reflects what matters most to property buyers and investors.

The Safety Score combines earthquake risk data (PGA values, seismic zone classification, fault line distance), terrain analysis (SRTM elevation and slope data), flood risk (JRC Global Surface Water occurrence), and nearby safety infrastructure (hospitals, pharmacies). A terrain adjustment bonus (0-15 points) rewards properties on stable bedrock with low flood risk.

Yes. Scores are designed to be comparable across locations. A Safety Score of 85 in Istanbul and 85 in Athens means similar safety profiles. This is especially useful for agents serving international buyers who are comparing properties across multiple countries and cities.

Standard and Investment reports include dedicated Walkability, Transit Access, and Bikeability scores displayed as SVG donut charts. These scores measure how accessible daily amenities are on foot, by public transit, and by bicycle — calculated from proximity to transit stops, amenity density, and pedestrian infrastructure.
