Sat2RealCity: Geometry-Aware and Appearance-Controllable 3D Urban Generation from Satellite Imagery

Imagine looking at a flat satellite photo of a city and instantly getting a realistic 3D model of all its buildings and streets that you can walk through, edit, and restyle. Sat2RealCity is a research system that learns how to turn overhead imagery into detailed 3D urban scenes while letting designers control how the city looks (materials, styles, lighting).

Executive Brief

Business Problem Solved

Urban and architectural teams typically spend many hours manually reconstructing and texturing 3D city models from maps, CAD, and survey data. This research line aims to automate generation of realistic 3D urban environments directly from satellite images, dramatically cutting the time and cost of early-stage city modeling, visualization, and simulation.

Value Drivers

Speed: Rapid creation of 3D city blocks from existing satellite imagery instead of manual modeling.Cost Reduction: Less labor-intensive 3D modeling and texturing for planning, visualization, and simulation workflows.Flexibility: Appearance-controllable models allow easy restyling of cities for different design options or scenarios (future developments, different materials).New Capabilities: Enables at-scale 3D urban twins for analysis, AR/VR visualization, training autonomous systems, and gaming/film environments.

Strategic Moat

If matured, the moat would come from training data (large paired satellite-to-3D datasets), specialized neural architectures for geometry-aware generation, and integration into city-planning and design workflows (sticky tooling).
