Today I’m sharing a post from a while back about a project I worked on for an architecture firm, looking at Madrid’s urban development since the 19th century.
All existing buildings in Madrid currently listed in the Land Registry database have their year of construction recorded. This map shows, by decade, where the bulk of that urban development took place. For example, in the 1920s it was in the Salamanca district, in the 1930s in Chamartín… shifting from development in the city centre to the outskirts.

CLIFFORD. VIEWS OF MADRID UNDER ISABEL II
The Canal Foundation presents ‘Clifford: Views of Madrid under Queen Isabella II’, an exhibition dedicated to the work of one of the pioneers of photography. It comprises a selection of almost a hundred images organised into four sections: ‘The Pleasures of Photography’, ‘Old and New Madrid’, ‘In the Service of the Monarchy’ and ‘The Construction of the Canal de Isabel II: a project worthy of the Romans’. The exhibition offers a glimpse of Madrid before the arrival of running water – a city very different from the one we know today, to which the most ambitious engineering project of its time managed, almost a century late, to open the doors to modernity.
Added Value of GIS and Geovisualization in Urban Evolutionary Analysis
- Spatiotemporal Data Synthesis: GIS facilitates the integration of disparate cadastral datasets into a unified spatial framework, transforming longitudinal construction records into high-density visual intelligence.
- Dynamic Morphological Tracking: The transition from static cartography to animated geovisualization (e.g., temporal GIF rendering) enables the identification of urban “pulses,” capturing the velocity and direction of sprawl, infill development, and densification cycles that remain obscured in traditional tabular formats.
- Heatmap Analytics & Kernel Density Estimation: By utilizing spatial Interpolation and density-based clustering, GIS highlights hotspots of urban intensity, allowing for a comparative analysis between centralized vertical growth and peripheral horizontal expansion.
- Infrastructure Correlational Mapping: Geovisual tools allow for the overlay of historical urban growth against transport network expansion, providing a technical basis for evaluating the causal relationships between infrastructure deployment and land-use evolution.
- Interactive Chronological Filtering: Modern geovisualization interfaces support granular temporal querying, enabling researchers to isolate specific socioeconomic eras and visualize the physical footprint of policy-driven urban shifts in real-time.
