SimpliCity: When Automation Meets 3D Urban Reconstruction

Understanding when to use SimpliCity and why automation matters

Urban reconstruction projects are becoming larger, more complex, and more data-intensive. From LiDAR surveys to smart-city simulations, organizations are producing massive datasets that need to be transformed into clean, structured 3D building models.

But not all reconstruction approaches are equal. Manual 3D modeling ensures precision but is slow and expensive. Conventional semi-automated tools improve speed but still require editing and quality control, typically difficult for complex buildings. 

So when does Simplicity make the difference?

Traditional 3D reconstruction vs. automated processing

 

Approach Workflow Advantages Limitations
Manual modeling Hand-crafted 3D creation from raw data High precision for small areas Time-consuming, costly, not scalable

Semi-automated tools

Combination of automation + manual correction Decent balance between speed and accuracy Still requires human validation
SimpliCity Fully automated LiDAR-based reconstruction Scalable, consistent, fast, geometrically compact and ready-to-use outputs. Ideal for large urban zones and national mapping   Prefers that point cloud and the building footprints are aligned 


SimpliCity
stands out by automating the entire reconstruction pipeline. It can process 17,000 buildings averagely per day  on a single CPU with 1 thread while keeping the models watertight, semantically labelled, and lightweight for easy visualization. The process is highly scalable with multiple CPUs and multiple cores.

When SimpliCity is the right choice ?

You don’t always need full automation. But in certain cases, it’s the most effective option:

Nationwide 3D modeling projects where scalability and consistency matter most.
Smart-city and digital twin programs needing frequent and high precision updates of urban data.
High-precision digitalization : tunable configuration to adapt to different level of precision requirements while preserving the topology. For high precision, fine geometry details can be reconstructed without introducing extra complexity for coarse structures. 
Telecom and energy simulations requiring high geometric accuracy at scale.
Government mapping agencies aiming to modernize LiDAR-based workflows.

In each of these scenarios, SimpliCity provides the right balance between speed, precision, and interoperability.

Results that accelerate urban intelligence

By automating the most resource-intensive part of 3D reconstruction, SimpliCity reduces production time and improves standardization across cities and countries.

It generates ready-to-use 3D models in common formats (CityJSON, SHP, PLY, STL and OBJ), fully compatible with GIS, CAD, or visualization tools.

That means:
faster data delivery,
lower operational costs,
and greater consistency for analytics and simulation workflows.

Why it matters?

Urban modeling is no longer just about visualization. It’s about enabling better decisions — from infrastructure planning to environmental impact studies.

By transforming LiDAR into clean, standardized 3D data, SimpliCity empowers planners, engineers, and researchers to focus on what matters most: insight, not data processing.
