City Digital Twin
A geospatial intelligence platform for urban analysis, policy design, and spatial decision-making.
What is CDT?
Every neighborhood, measured and mapped.
5,000+ census sections across Catalunya, each carrying hundreds of data fields — housing, morphometrics, economics, mobility, and research indicators — all queryable, visualizable, and comparable.
Platform
Multi-scale spatial
intelligence
CDT organizes Catalunya into a hierarchical spatial model — from individual census sections up through municipalities, comarques, and provinces — each level carrying aggregated metrics and boundary geometries.
Navigate any scale. Query any metric. Compare any region.
Housing & Real Estate
Cadastral parcels, building heights, land use classification, and property value analysis across 5,000+ census sections.
Urban Morphometrics
Street-level morphological indicators — building density, setback, coverage, and enclosure — computed per section.
Economic Intelligence
INE census data, income distribution, employment patterns, and economic activity mapped at the finest administrative grain.
Mobility Networks
Road hierarchy, transit stops, metro and bus coverage analysis with isochrone-based accessibility scoring.
