Mr. Lin Dongyu, General Manager of Chung Hsing Surveying Company, said, “We have always been committed to providing the highest quality surveying services, and the introduction of the RIEGL VMX-2HA Mobile Mapping System is part of our pursuit of excellence. In Taiwan, there are densely populated metropolises and complex mountainous roads. The use of this technology will bring more value to our customers, allowing us to meet a variety of survey needs, whether it is road facility surveys, highway slope surveys, urban planning or high-definition maps for autonomous vehicles applications.”

LINKFAST Technology Co., Ltd, RIEGL’s authorized distributor for Taiwan, hosted a demonstration of the RIEGL VMX-2HA in collaboration with RIEGL’s Asia Pacific office. The field operation and post-in-house processing solidified the decision by CHS to invest in this technology. LINKFAST was instrumental in the delivery, installation, system operation, and data processing training that allowed CHS to successfully use the VMX-2HA to execute their projects in a short period of time.

Marcos Garcia, Business Development Manager for RIEGL in Asia Pacific commented, “Mr. Dongyu’s commitment to acquiring the most advanced geospatial technologies in the market shows his lifelong dedication to improving data acquisition in Taiwan. I personally admire this drive which spans several decades since the founding of his company back in 1969. Dean Yang (LINKFAST) and his team have once again proven their high level of skills with some of the most complex RIEGL systems. We are proud to have LINKFAST as partners in Taiwan and will continue our commitment to support all their efforts.”

CHS is excited to include RIEGL’s Mobile Mapping LiDAR technology into its service portfolio to meet the growing needs of the surveying and mapping market and to ensure that clients receive the highest quality data. One of the first projects CHS handled successfully by using the RIEGL VMX-2HA Mobile Mapping system was the collection of slope data for the Directorate General of Highway, MOTC.

Central Cross-Island Highway Slope Safety Investigation, Directorate General of Highway, MOTC

For this project, the main focus was on collecting high-accuracy and informative slope data by mobile mapping. The RIEGL VMX-2HA Mobile Mapping System is well suited for this application, as it acquires more than 1,500 points per square meter, its scanning angle is suitable for slope scanning (especially for steep slopes), and it acquires data from the area that may be obscured when using drone aerial photography.

CHS’s multi-functional surveying and mapping patrol vehicle is based on the RIEGL VMX-2HA system.

The delivered outcrop point cloud with absolute coordinates enables 3D viewing, distance, area, orientation measurements, and slope analysis. Change detection can also be performed by overlaying point cloud data from multiple periods. Further analysis on structural geological, interpreting the altitude of surface of discontinuity, and evaluation on hazard area, such as rock-fall mechanism analysis can also be carried out.
