GTEC3D Completes High-Accuracy 3D Laser Scanning at Historic Todoroki Suigen in Japan

We are proud to share a recent milestone: GTEC3D was selected to perform high-accuracy 3D laser scanning at the remarkable Todoroki Suigen in Uto, Kumamoto Prefecture, Japan, and the scan is now successfully complete.
 
This project represents a significant contribution to documenting and preserving a vital piece of Japanese cultural heritage using cutting-edge technology.
 
 
3D Laser Scanning in Preservation

A Landmark of Natural & Historical Significance

Todoroki Suigen is not just a natural spring; it’s a revered landmark renowned as one of the “Three Great Springs in Higo.” Its significance extends deep into history, primarily because it is home to Japan’s oldest active waterworks.
This unique combination of pristine natural beauty and functional historical engineering makes it a popular destination for visitors from around the world. Tourists consistently visit the site to tour the waterworks, experience the serene natural scenery, and appreciate this remarkable, nationally recognized site.

Key Historical Facts:

The Role of 3D Laser Scanning in Preservation

Capturing such a deeply meaningful and complex location demands the precision that only high-definition 3D laser scanning can provide. Our team at GTEC3D utilized top-of-the-line survey equipment to digitally document the site with millimeter accuracy.
 
Specifically, the project was executed using a combination of the Leica Geosystems RTC360 laser scanners, the Leica iCON 82 Robotic total station, and the Leica GS18T GNSS RTK Rover.
 
This data acquisition process supports modern historic preservation efforts, creating a detailed digital twin that can be used for future restoration planning, virtual tours, engineering analysis, or Scan-to-BIM (Building Information Modeling) applications.

Our Gratitude

It was a profound honor for GTEC3D to capture this culturally significant location. We are grateful for the opportunity to support the ongoing documentation and preservation of the Todoroki Suigen landmark. We look forward to sharing insights from the finalized data soon.
