LCA-GCS: Large City Architecture - Generated Cityscape Set The Large City Architecture - Generated Cityscape dataset (LCA-GCS) is a comprehensive collection of 585,600 AI-generated images representing architectural features of 5,856 global cities. Created using advanced diffusion models, this dataset offers 100 samples of various architectural types for each city with a population exceeding 100,000. LCA aims to facilitate comparative analysis, synthesis, and learning from AI-represented architecture, providing a unique resource for researchers, urban planners, and AI developers interested in global architectural trends and urban design.

Dataset Description The LCA-GCS-set represents cities by situating architectural features from details to interiors to urban forms uncommon for existing databases in a flat ontology that allows to search and compare architectural representations in various ways. We hope that the LCA-set benefits future research that could identify recurring spatial configurations, material palettes, and design elements characteristic of specific regions, cultures, or building typologies. Building on it, the synthetic dataset can contribute to e.g., training site-specific models, identifying commonalities, or extracting features that are difficult to access in existing data.
