LiDAR - Creation of a digital spatial 3D/2D model of the Tunnel

Project Details

The project involved the creation of a digital spatial 3D model of a 25-meter tunnel, along with 2D cross-sections and longitudinal sections. The data was processed using Bentley MicroStation and Terra solid, resulting in a highly accurate model suitable for a range of applications including design, construction, and inspections..

Location: Czech Republic

Technology and Software:

Bentley MicroStation: Used for 3D modeling and generating 2D cross-sections
Terra solid: Employed for LIDAR data processing and model refinement

People:
The GisPoint team, with expertise in LIDAR data processing and modeling, delivered this project. Their skills ensured the creation of a precise digital model that meets the needs of structural analysis and future maintenance work.

Process & Challenges

Process:

Data Acquisition: Laser scanning data was collected to capture the tunnel’s geometry.

3D Model Creation: A detailed 3D model of the tunnel was generated using Bentley MicroStation – Terra solid.

2D Section Creation: Cross-sections and longitudinal sections were produced for a comprehensive structural overview.

Accuracy Checks: The models were reviewed to ensure high precision and usability for various infrastructure applications.

Challenges:

Ensuring the 3D model captured the exact structure and geometry of the tunnel with high precision.

Processing detailed cross-sections that align with the real-world dimensions of the tunnel.

Managing large volumes of LIDAR data efficiently within the project timeline.

Result

A highly accurate 3D model of the tunnel, along with 2D cross-sections and longitudinal sections, was successfully delivered. The model provides detailed insight into the tunnel’s structure and can be used for project planning, construction, and maintenance tasks.
